Clint, FYI, got the RAM, installed VP3.0, no problems w/installation, ran the tutorial stuff, screwed around a bit…. THIS THING IS GREAT!!! love it!! 8^)

Barry: Glad you like it! <grin> Let me know if you have any questions. Clint <VRLI>

geez… I was just reading an e-mail message when the VP3 rendering in the background got done and suddenly filled the screen!! Talk about not-so-subtle introductions!! I did a Pikes Peak from the ENE w/trees, clouds, 'n stuff, but apparently my camera is too low, as I'm looking at PP through branches (what's the symbol for sh*t-eating grin?? 8^) )… bitchin'…. I showed a quick n dirty PP render to an employee whose an engineering student and is vaguely familiar with the Amiga. His response was "if I were a civil engineer, I'd be on the floor in ecstasy!" Three thumbs up! I haven't quite got the hang of the color IFF file->Alt bit… the tutorial didn't mention the levels had to be *certain* colors, but I tried to run my IFF through the IFF->Alt and back to IFF, then assign the colors in order of elevation and rerun through IFF->Alt…. make sense?? Anyhow, I've had it running for less than 24 hrs, and so far so good. It's fun to play with and fun to watch work… now if I could only have time to *really* tinker w/it…. – Barry Jarrett ** letting my Amiga do all the work…. on Autopilot!! **

Barry: There is a "VideoNoDisplay" command in the script language that will allow you to render to the 24 bit buffer, but doesn't do the display after it's done. I know the screen to front at the end is annoying, and I probably should have changed it to a screen beep, but that was one of the 'wish book' items which didn't get done due to time considerations. Actually, it's color register numbers that are important for the IFF->Alt function. It's described on pages 2-19,2-20 of the manual. I'm glad you're having fun with it! That's what it's there for. <grin> Clint <VRLI>

Clint, I'm having some real SLOW renders on my A4000 on VP3.0. Any suggestions? Clark -|- Williams –O-o-O– Via George

Clark: Grass will slow the rendering time considerably, as well as pushing all of the Crown and Detail values on trees. Tree density is a big factor, as is the proximity to the ground that the camera is placed. (ie … near to the ground will be slower than farther away.) A typical rendering with Altitude texture set to H and Poly size to 1 with trees and clouds should run about 30 minutes on the 4000. If you look at the polygon count (see About Image) you will see about 1,000,000 or so polygons. Some images will come in alot higher for alot of reasons. Rendering rates of 600-1000 polys/second are common on the 4000. Are you running 3.03? Clint <VRLI>

Clint, Got my 3.03 upgrade yesterday and I'm VERY impressed. Render times are a little longer than I'm used to when I render at highest quality but the images are worth the wait. I do have a couple of suggestions for the program though: 1. A small 3 ring binder would be nice for the manual. With the 3.03 update I now have the VisatPro 3.0 manual, the tutorial manual, the script language manual, the terraform manual, the terraform 2.0 suppliment, and the makepath manual. It would be nice to be able to hole-punch the small manuals and put them into the VistaPro binder to keep everything together. It'd also be cheaper for VRLI since they'd only need to change a couple of pages on the manual for the Windoze version. Might be worth suggesting to the management at VRLI. 2. I noticed in the manual that you can't have the camera above the clouds. I've found that punching through a cloud bank is a good transition from an Imagine rendering of a planet to a Vista rendering of an island. You can then drop down to the ground level and do a landscape anim. I understand that this limitation comes form the fact that VistaPro renders clouds first and then the landscape, and that if the camera is above the clouds the landscape will be drawn over top of them. Perhaps it would be possible to modify the rendering routine so that it checks the altitude of the camera and clouds and if the camera is above the clouds they're rendered last otherwise they're rendered first. (Or I could just continue to use AdPro for the transitions.) ;^) 3. I though the forward, port, and starboard camera postions are a neat feature, but why no aft view? If you rotate the camera 180 degrees and do another forward to use as an aft view will the edges still line up? The reason I ask is because this sounds like an easy way to do an anim of a camera rotating in position but you only have to render 4 frames. How about a button to render all 3 (or 4) automaticly? :^o <continued>

Jeff, To get the "rear window" view you need to rotate the Heading 180 degress, and negate the Pitch and Heading. For instance if the forward camera is pitched up by ten degrees the rearward camera is pitched down by ten degress. The same goes for the Bank. Remember the images only "line up" at the Wide lens setting (16). Even so, shifting through the set of four images is not the same as rotating the camera. Vistapro (and all other rendering programs) are designed to render to a flat surface — the screen of your monitor. To do what you suggest (render four images and scroll through them) would require a cylidrical projection for accuracy. On the other hand you may be able to live with the difference under some circumstances. I don't know how noticable the difference is since I have never done it. The main reason for the Port/Forward/Starboard settings was for a travelling demo that uses three large projection screens with the viewer sitting in the center to give a feel of total-immersion. Front +———–+ | | | | Port | Viewer | Starboard | | | | + + The back side is left open so you can get in and out, and so that people standing outside can see what's going on. Under these circumstances it wasn't necessary to generate the rear view. And on the PC version (where all the non-amiga-specific development was going on) there's no left room left on the Lens panel for another button! The biggest problem with having a camera above the clouds is that it requires transparecy in the rendering — too much trouble to add in this version (and it will slow things down). It will probably be in the 4.0 release…. John.

Hope you're feeling better… Have you had any time to dig up the details to tell me how to get that color/elevation info?

4. Save Turbo Silver? I'm surprised that hasn't been changed to save Imagine. With the price of Imagine 1.1 and 2.0 Turbo Silver is pretty much a dead product. Save Imagine would also apply to the Windoze version. I hope you don't think I'm nit picking too much. These are all really minor points and as I said before I'm REALLY impressed with the new version. Of course if you squash all the bugs in VistaPro and you start getting really bored…… :^)
#28622From: Peter GreciApr 7, 1993 4:34 PM
Jeff, even tho Vistapro "Save's Turbo Silver" you can load them puppies right into Imagine. PROVIDING you have the Humongous amounts of RAM this requires. There's ALOT of Polygons in them DEM files when converted to Turbo Silver.
#28727From: jeff HolinskiApr 9, 1993 6:46 PM
I know they will load into Imagine. My point was that probably 99.6% of the people saving landscapes as Turbo Silver are using Imagine these days. Might as well just change the menu and file format a bit and drop the older version.
#28662From: SyndesisApr 8, 1993 4:42 PM
Imagine and Turbo Silver use a very similar IFF-like file format, so Imagine loads TS objects just fine. Imagine objects have a few extra hunks that contain extra info that TS can't use. Turbo Silver 2.0 is a different beast altogether – if you need to take TS 2.0 objects (say, from Impulse's old "Terrain" program) to Imagine, you can use a translator program like InterChange Plus.
