Rick, Is Impulse going to have a "Textures.kit" in their next release of Imagine. If not, are they going to release a "Textures.kit" in some other form? I really liked this capability in Turbo Silver SV and hope to continue using it with Imagine. The Silver textures (as I'm sure you already know) are not compatible with Imagine. The Marble texture in particular is sorely missed. The Imagine wood texture is nice, but it's no substitute for marble. Thanks, Terry T.

Terry, I believe a textures kit will be forthcoming, but Impulse will first be completing its paint program for the Firecracker. Did you ever create any textures for Turbo? Which ones? –Rick
#21612From: Terry L. TaborFeb 18, 1991 9:06 PM
Rick, I did some exmentation with the provided wood texture and created some new marble textures. I thought my textures looked better than the ones that came with SV. I'd have uploaded them here if I hadn't lost them in a Hard Drive Crash. I've been waiting for the kit for Imagine before I take the time to recreate them, but with the news that it might be a little while before the kit is available, I might re-do them for SV. I like using the textures better than brush wrapping because they use less memory. Although the brush wrapping capabilities in Imagine are incredible! I'm just scratching the surface of what Imagine can do… Too bad I have to work for a living! Thanks, Terry T.

Terry, what I enjoy most is being able to wrap 24-bit images. These are so satisfying and make creating photorealistic scenes very easy. –Rick

Rick, Hmmmm… I'd never even thought about using 24-bit brushes. Doesn't that eat up your memory awfully fast? I know super bit-maps do. Don't get me wrong, I do like and use brush maps. I've liked the textures though because they don't take as much memory. Terry T.
#21659From: Stan Kalisher (Impulse)Feb 20, 1991 3:18 PM
Terry, I'm using a nine-meg setup, so I haven't gotten in trouble. I've used up to five brushes, all 24-bit 768×482, in a single scene. I suppose if I pushed it much beyond this point I would reach my memory limit. It's a lot of fun, though and the 24bit output is spectacular on a Firecracker or Toaster. –Rick

Rick, I'll have to try that. I don't own a 24-bit buffer but I generally render in 24-bit and convert using TAD because I like it's dithering better. The thing that's been keeping me from getting a 24-bit buffer has been that to use it to good advantage you need a single-frame recorder. I noticed recently you said you have done this by "hand" using a Sony 9850 and an edit controller. How much does a 9850 cost? Can this be done with a Panasonic AG-1960 or the new Sony S-VHS unit (SLV-R5, I think)? If I could get into single frame recording for say $1500, then a true buffer ala Toast' or 'Cracker would be feasible for me. I'm not afraid of a little work. I've tried to do single frame with my present recorder (Sony SLV-757UC) and it's close, but not usable. It will work three times in a row and then be off by 2 frames. Also there is sometimes some weird color shifts in a frame. If I can't get into a single frame recorder at a reasonable cost, I'll probably end up with a Ham-E or DCTV pretty soon. Thanks, Terry T.
#21681From: John PendergrassFeb 20, 1991 9:28 PM
Terry, I went thru same dilemma on 24bit boards (wanting one, but realizing that they required frame-by-frame to do anims with). I now have a HAM-E which gets me about 90% satisfaction, for about 10% of the price. I usually use the 256 color mode, which looks pretty darn good, and is easy to animate with. Have the same limitations on real-time anims as you do with hires anims (ie. watch the amount of changes, etc), but its very feasible. Someday I'll likely get a full frame buffer (the FireCracker sounds great), but for now the HAM-E is doing me just fine. Just thought I'd throw my .02 dollars in. ttfn –jp–seattle–
#21689From: Joe KuzmaFeb 21, 1991 3:33 PM
John, I also have a HAM-E, and I find that images I ray-trace in full 24-bit mode turn out excellent in the HAM-E mode (18-bit mode). I've rendered some items utilizing Sculpt-4D in 24-bit 320X400 mode and the results were outstanding. One thing you have to do is turn the DITHERING OFF. If you keep DITHERING on in the rendering, displaying them in the HAM-E 24-bit mode will look less than satisfactory. Try rendering in Imagine with the dithering turned off, and I'm sure you'll see a big difference in the REG modes & HAM-E modes. Joe
#21696From: Stan Kalisher (Impulse)Feb 21, 1991 8:25 PM
Joe, Imagine automatically disables all dithering when rendering in 24 bit. –Rick
#21719From: John PendergrassFeb 22, 1991 11:53 AM
Really Rick? That's great! It's been a pain to keep resetting object attributes for 24bit or standard HAM, etc. (I don't remember that tidbit in the manual?) –jp–seattle–
#21701From: Terry L. TaborFeb 21, 1991 9:13 PM
John, It sounds like we're in the same boat! If I understand what you're saying, it sounds like you prefer 256 color Ham-E to the 262,…? color Ham-E mode because it plays faster? I'm guessing that that's because when there are more colors available and more colors on screen, then each frame has more changes than the same animation with less colors. If this is so, how does 256 color mode compare with straight 4096 Ham as far as appearance goes? When working in the 262,… color mode, how small do your movements end up being to keep full speed animation going? Is it a severe limitation, or merely something to be careful with? I typically work in 352X440 Ham mode and only rarely have speed problems. Have you ever compared Ham-E with DCTV? I've heard some discussion about DCTV's composite output being poor when compared to the Ham-E RGB. But since many people (myself included) want to record the output on a VTR anyway, a better comparison would be a comparison of DCTV's output to a composite encoded output from Ham-E. For my purposes, the DCTV seems to be a better buy assuming the composite appearance is as good and animation speeds are the same. All else being equal, the only draw back for me would be that DCTV can't be Genlocked. I don't yet have a digitizer and that's a plus in the DCTV column. But, appearance and playback speed definitely take priority. Any info you have would be appreciated. Thanks, Terry T.
#21717From: John PendergrassFeb 22, 1991 11:53 AM
Terru, re your questions about HAM-E anims, etc: 1) prefering HAM-E 256 color (Register) over HAM-E 262,000 color (HAM-E). Register usually plays faster in large change anims, as long as the palette is optimized. HAM-E is much more likely to generate larger delta files, and slower anims. But that may be partly due to the fact that there is currently no way to guarantee the same base palette in different HAM-E mode images. That may help (when they put that option in); I won't know till I see it. For now, the Register mode is easier to use for large change anims. When doing DPaint style anims (ie with basically static backgrounds, and animated brushes), however, I haven't seen much speed difference. (HAM-E Paint software has a wonderful ARexx-based animation program that makes this style anim easy) As in all ram-based anims, keeping the delta changes to a minimum speeds things up. How small do you have to be? I don't know. I have no problems with several 1/2 screen brushes moving at once (get 15fps or so), but I have an 030. I don't find it any real limitation at all, except that a full screen anim with tons of changes (ie scrolling background, etc) is going to be slow regardless. I have seen DCTV, first at AmiExpo, and lately at a local dealer. Of the two I prefer HAM-E considerably. Aside from all the questions of recording quality, etc (which Ben or someone else is better qualified to answer than me), there is the software question. I currently use the HAM-E paint and IP software, and it is spectacular. I guess I wonder if DCTV will be able to match that software performance. I've always claimed that the software is only as good as the artist using it, and I suppose I could extend that to say that the hardware is only as good as the software supporting it. DCTV may be the right choice for you, for many reasons. But, as in all things, I'd advise seeing both, trying both, thinking hard about that $300-500, and then deciding. Hope this helps. –jp–seattle– [ MORE ]
#21726From: Terry L. TaborFeb 22, 1991 8:25 PM
John, Thanks for the info. I've "glimpsed" both the Ham-E and the DCTV units, but never side-by-side and never for very long. Unfortunately, the Amiga dealer in this area tends to pull everybody to the Toaster saying things like "Nah, what you really need is …". I've got to admit the Toaster is nice, but currently, I don't think it meets all my needs. He did tell me that Newtek is working on some kind of a Ram system that will allow limited (2 to 4 secs) animations of full resolution 24-bit screens. If that rumour becomes a reality, then maybe the Toaster is in the cards… Thanks again for the info. Terry T.
#21766From: Black Belt SystemsFeb 23, 1991 6:00 PM
When converted to Composite, DCTV and HAM-E will be approximately equal. However… :^) You can use a DigiFEX encoder to convert HAM-E images to S-VHS. These will look considerably better than standard composite – and you can't do that with DCTV., Ben Amateur Radio Callsign is A A 7 A S

Terry, I understand that the Panasonic 7500(?) is the only SVHS recorder they sell which is frame accurate. It 's a shame, because at present you really can't get into single frame recording for under $6000 in video gear. The 9850 was around $8K, I believe. –Rick
#21700From: Terry L. TaborFeb 21, 1991 8:48 PM
Rick, Sigh… It looks like you lucky guys get to have all the fun! Maybe a single frame recorder is around the corner for the "prosumer". There seems to be a good demand for one. In the meantime, it sounds like I'll have to get one of the quasi 24-bit boards (Ham-E or DCTV) and ease into the 24-bit waters. Thanks for the Info, Terry T.
#21798From: BRAD HAYESFeb 24, 1991 11:30 PM
Terry: I just got TAD today. ofcourse the very first thing I tried was a 24-bit Imagine file. I dont think I got it right though… In the Project editor (of Imagine) I selected RGB8, but dose it matter what presets I select ( Hi Res or Ham ) ??? And once I got to TAD my image lost most of it's dithering. It looked much better as a Ham image. What's the correct procedure…. Any help is good help. Brad Hayes
#21802From: John PendergrassFeb 25, 1991 10:06 AM
Brad, the RGB8 you created in Imagine had NO dithering. So TAD/ADPro did right to not put any in (unless you tell it to). Remember that when you render an Imagine pic in 24bits (RGB8) and choose show, it automatically reduces it to an Amiga HAM mode with dithering, but the actual source has more color info, and no dithering. Imagine is just trying to let you take a peek at an otherwise undisplayable image (24bits). Rick (of Impulse) recently posted here that Imagine automatically shuts all dithering OFF when you select a 24bit image format. (even if you have it on in the objects, etc). You should be able to use the TAD/ADPro Floyd-Steinberg dithering, (or another) to get your nicely dithered image back. –jp–seattle–
#21824From: Terry L. TaborFeb 25, 1991 8:15 PM
Brad, I generally render in ILBM-24Bit mode rather than RGB8-24Bit so that might have some affect, but I think it should be the same only you should use the Impulse loader for RGB8 and the IFF loader for ILBM. As John P. pointed out, the Auto Dither box in the projects menu only effects the show command in Imagine and does not effect the image data itself. Also, as near as I can tell (ask Rick Rodriguez to be sure of this), when renderring in 24-bit, the HAM switch doesn't affect the image at all. The HiRez switch (I think) affects the display mode. That is if your image size is 640 by 400 and HiRez is set, then it is a HiRez display mode and the size of a normal display. With HiRez not set, the same sizes would yield a LoRez display mode, but in a super bitmap size (i.e., bigger than the display). I'm not sure what happens when both HAM and HiRez are set as that really doesn't make sense. In any case, using the scale and screen controls in TAD you should be able to take in any image from Imagine and generate (in TAD) the exact size, display mode, and number of colors you want, subject, of course, to the limitations of the Amiga's display. I think, as John P. also pointed out, that you probably didn't use any of the ditherring options when you were in TAD. I personally favor the Floyd(1), Burkes(2), or Random(6). Hope this helped you some. For more info on wrapping, see my message to Mike Egan about Imagine Altitude Mapping. Terry T.
#21709From: SCOTT BUSSEFeb 22, 1991 9:33 AM
Rick, speaking of reaching memory limitations, I have just run into the old problem of having objects missing from ray trace renders, the way it happened with Turbo Silver. The object setup was filling an area just approaching – and + 600 on the X axis, so I put in a size line in the globals increasing the universe to 2048. When I did the traces, the man, his desk and chair were all gone from the scene. Subsequently, I shrunk the ground axis so it would fit into + and – 512, and then removed the global size line. The image then rendered fine. Something tells me that the same bug that plagued Turbo and its world sizes is back again… What do you think? BTW, when the world size is set in globals to 2048, does that effectively mean "up to 2048 on all axes", or does it mean "up to 1024 on all axes", for a cubed area of 2048? Thanks! Scott
#21742From: Brian MaguireFeb 23, 1991 7:29 AM
Scott, could you explain that bug a little more? That is exactly what is happening to me with one of my images and it is driving me nuts! Do you have to shrink your larges axis in order to get around it? -Brian
#21857From: SCOTT BUSSEFeb 27, 1991 3:34 PM
The bottom line seems to be that everything must fit within a 1024 area centered around the 0,0,0 axis point, and no increase in the world size (on the globals size line) is functional… Scott
#21589From: Karl SparklinFeb 17, 1991 2:33 PM
Terry, I just got a mailing this week from MicroSearch offering a new package of high-res (704 x 480) HAM images for brush-wrapping, including stone, marble, brick, etc. They note that future releases will have wood, cloth, and organic textures. They have a pic in the literature of 5 bowling pins of various map rendered with Imagine. Though in B&W, it looks very good. My order went out yesterday. Karl
#21611From: Terry L. TaborFeb 18, 1991 8:43 PM
Karl, Thanks for the info. I'll have to check them out. My main interest though is in the "structured" textures as they use much less memory and provide (in a way) more resolution than the brushes. I have been experimenting alot with brushes in Imagine however. Especially now that we can put multiple brushe on the same object. One of my favorite techniques is to use the same brush as both an altitude map and a color map on a sphere… Instant planet complete with surface contours. Good brushes for this technique are Marble, Wood, and Fractals. Terry T.
#21613From: Karl SparklinFeb 18, 1991 9:07 PM
Terry, Hmm, sounds interesting! I'll have to try that! Ever think of UL'ing an image or two? I'd like to see one. Karl
#21636From: Terry L. TaborFeb 19, 1991 6:06 PM
Karl, I hadn't thought of uploading, but that's just because I never have. I'll try uploading a sample or two in the next day or so. The results are very striking (at least to my eye)… Terry T.
#21640From: Karl SparklinFeb 19, 1991 8:40 PM
Terry, Great! I'll be looking for them. Karl
#21648From: Terry L. TaborFeb 19, 1991 11:42 PM
Karl, I just uploaded a frame from a recent animation I did that has a good example of an altitude and color mapped planet. It also contains a brief summary of the tools and techniques I used. The animation is quite nice (and quite big-4 Meg) at least by the standards of things I've seen. It depicts some Star Wars vehicles flying away from a small planet while the camera kind of follows the vehicles on their flight. The planet is slowly rotating. Too bad I can't upload the whole animation, but at 4 Meg that's pretty farfetched. Tell me what you think of this image. It's my first upload so go easy on me if you think it stinks! I'm pretty proud of it. The animation is VERY impressive on my 27" JVC. George Lucas might even be pleased! Oh, by the way, I uploaded the file (named PLANET.LZH) in the AmigaArts section under "Raytraced Art". Download time should be about 3.5 minutes at 2400. Terry T. P.S. The Sysop should post it in the next few days.
#21661From: Karl SparklinFeb 20, 1991 6:34 PM
Terry, Terrific! I'll be drooling to download! Karl
#21615From: John PendergrassFeb 18, 1991 9:20 PM
I also vote for a texture creator. (or better yet, an editor, but that's a bit much) I experimented with the texture kit of Silver, but never really got anything…. oh well. You sound like you are having great success with brushes. I have tried the multiple brush stuff too, with minimal success. Individual maps work ok, but combining them seems to create a real muck at times. Any particular hints? –jp–seattle–
#21637From: Terry L. TaborFeb 19, 1991 6:23 PM
John, Hints? Well, I'm not sure what it is I'm doing that seems to be working. I think one of the things I found (Impulse might want to correct me as to the details) is that when using "Wrap Z", the X size should be 1, and likewise, when using "Wrap X", the Z size should be 1. Additionally, when using "Wrap" as opposed to "Flat", the axis likes to be at the center of where you want to wrap around. As an example, for a sphere at (0,0,0), I would use both wrap X and wrap Z with X size of 1 and Z size of 1. It seems to me that the sizes when using the "wrap" mode relate more to the number of times your brush will wrap around the given axis. Oh, I didn't finish my example! I would then put the brush at position (0,0,0) also. To sum up, it seems to me that the sizes (of the brush) mean different things for "Wrap" and for "Flat", and also, the brush axis location wants to be at different locations for "Wrap" and "Flat". I told Karl I would upload some sample images. You might look at these and if what I've told you above doesn't make sense, I'll upload an object example. Terry T.
#21658From: John PendergrassFeb 20, 1991 1:28 PM
Thanks, and you did make sense. 🙂 I noticed that Rick from Impulse uploaded a brush wrapping tutorial, Wrap.lzh, so between the two of you I hope to solve the multiple-brush technique. Thanks again. –jp–seattle–

They do indeed look nice, picked them up a couple of weeks ago. The info enclosed says that you can special order the original 24 bit images from them too. Bill Carey – via Whap!

Bill, Were you referring to those MicroSearch textures? (I'm not sure what thread this was) Karl
#21781From: Bill CareyFeb 24, 1991 10:09 AM
Yep, the Micro-Search.
