I have a diamond Viper video card….and i have misplaced the second disk which has the 24 bit driver on it…i was wondering if there were any 3rd party drivers which you were aware of that i could download….320*200 is getting annoying….

Jean-Louis, I _think_ Panacea might have a demo driver here in the libraries that will work for your card. Also, you should be able to use VPRMODE VESA (a Viper utility mode) with rcpvesa.exp using set rcpadi=\3ds2\drivers\rcpvesa.exp to at least get high resolution, although at only 256 colors. John

Thank you i'll try them both……..but if anyone else finds a 24 bit driver please tell me….

Vibrant Graphics has an excellent driver available for your card. Their phone # is (512) 250-1711. You get 24 bit RCPADI for the materials editor and the render/view, which you don't otherwise get. No more 8-bit viewing of 24 bit images! John Tissavary (La Luna cie)

Hello Jean-Louis, Hey! Gotta get that Viper rendering in 24-bit! There is a Diamond BBS that will have those drivers. Call 408.524.9301 and I'm sure that they will have the latest drivers. I believe Panacea has some free ones on this forum. Also, Diamond can be found here on CI$, I think in the GraphDev forum. If worse comes to worse, let me know and I'll Email you the disk! -Alan Iglesias

Alan; I want to buy a new video card. I now have a 256 max color Video Seven VRAM VGA card and an NEC MultiSync 3DS monitor. I want to go to at least 16 million colors at 800×600. Will the Diamond Viper do this with the drivers just discussed for 3D Studio? I have an ISA bus computer. If this board is not compatible to my computer, or 16 million colors are not available at 800 x 600, is there another card that could be recommended? Thanks! Dennis

The Viper VLB card does all that and more, Dennis, but unfortunately it *is* a VESA Local Bus video adapter. There are quite a few 24-bit VGA cards out there (all seemingly very supported by the Vibrant drivers in r3) starting from the 79$ Cirrus Logic unit (24 bit @ 640×480) and moving right up the scale. The Hercules entries seem to be very well received here on the forum, and are capable of some great display options. Many folks I know like the Diamond 24x, but I think that it may top out at 640×480/24 bit as well. Anyone?? FWIW, I find 640×480 to be a great true-color res for 3DS pics, if a little scanty for Windows graphics apps… Maybe others could jump in here with more advice… -Alan Iglesias

Alan; Thanks for responding. I was thinking of getting a less expensive board at this time in hopes of upgrading to a Local Bus Computer within a year. So I particularly like the sound of a $79.00 board. Dennis

I am going to jump in here and mention that LOCAL BUS motherboards are not expensive. Multi-speed and upgradable two slotted (Local Bus) and 6 ISA slots with a 128K cache upgradable to 256K. Can use 33/50/25Mhz 486 cpu. Only drawback is they only hold up to 32MB RAM. However, these can be purchased without the CPU for less than $150.00 AMI BIOS and SIS Chipset. EISA boards with two LOCAL BUS slots start at $400.00. These mothers(boards) have a 256K cache, expandable to 512K and 1MB. Ram is expandable from 4MB to 256MB, 8 EISA slots and 2 VL-BUS slots and a ZIF socket for a Pentium Chip. AMI EISA BIOS and SIS EISA/VL Chipset. I don't mean to be advertising here but from the message thread I got the feeling that you thought the VL boards were very expensive. (In some magazines they are). Merlin G.

Merlin G Farmer; Thanks for jumping in. I'm glad you did. Sometimes I find myself in "tunnel-vision" mode and need to be snapped out of it. In my looking around, even at motherboards, it seems that there are so many to choose from, and the prices vary so much. A local store sells them from $250 to $995. The $995 model is a 66Mhz model with CPU. Yet before I buy a motherboard for that price, I can get a whole computer at 66Mhz with a monitor and a 340 Meg Hd and 8 Megs of RAM for $2000. Supposedly I can put a 66Mhz CPU in my motherboard, but it is an ISA bus board, and the CPU is over $500. So with so many options, it becomes confusing which way is the best way to go. I like the Idea of getting another inexpensive motherboard, and then buying the local bus video card that will be state of the art (for at least a year). 🙂 Thanks again for the input. Does anyone else have some suggestions. I really appreciate comments. The more input I get, the more informed decisions I can make. Dennis
#55391From: merlin farmerAug 29, 1993 11:31 PM
Glad to be of help. Yes I agree, with input from many it can make a decision easier, on the other hand, it can be too much info and make a decision harder. I personally would go for the cheaper motherboard and the higher grade graphics card. I speak of this because I went with a less expensive graphics card and a hi grade expensive motherboard, at that time all 486 motherboards were expensive. I use a Cardinal SnapPlus Video board, it could be better, but it does allow me to output with genlock, the input is what is poor. If I had to do it again now (and I wish I could,) I would have gotten the Targa board and stayed with my 386. Merlin G. Farmer

Dennis, I like the Hercules cards for this resolution. Veery simple and stable card .. but very fast! Look for the Graphite Pro 2MB VL. Now if you in the mood to really spend some money, you could get the Matrox MGA Impression 3MB/Z (list price around $1,500). Now this card will do 1024x768x24bit AND has a realtime shading chip onboard for realtime Goraud shading. They have implemented this in thier ACAD driver and I think it's only a matter of time until they have a 3DS port of the software. Ang
#55242From: Dennis FenskeAug 28, 1993 12:42 PM
Ang; I was looking at that board. I got some specs on it and it sounds good, but I haven't heard much talk about it on the board. I believe that some were talking about a different version or model that had limited 3DS drivers. I was hoping that someone would know about it. It's a bit more than I want to spend at this time, but I am keeping it in mind. Thanks for mentioning it. Does anyone have more input on the capabilities/limitations of this board? Dennis
#55258From: MARTIN G FOSTERAug 28, 1993 3:53 PM
Dennis, I think the Matrox MGA is somewhat ahead of its time, at least for 3ds users/Windows graphics users. Sounds very appealing to Acad users who may be more willing to spend a lot for interface speed and fast shading. It's very expensive and I think most people, including me, will settle for 1/2 the speed, for 1/5 to 1/10 of the price.
#55298From: Dennis FenskeAug 29, 1993 9:57 AM
Martin; Thanks for your reply to the MGA cards. I was wondering if this was in competition with the Targa boards. If so, then maybe it is not too expensive. There is an option for an output to tape directly from the card. Dennis
#55332From: MARTIN G FOSTERAug 29, 1993 3:09 PM
Dennis, I don't think the MGA boards are meant to be competition for the targa+/vista board series – that would be the Matrox Illuminator Pro series. They are more like extra hot Acad/Windows display cards. You see you need a framebuffer _in addition_ to your main display board to accomplish frame-by-frame output. A frame buffer is simply a memory location on a card (or in an external box) which can store a frame, while you are doing other things with your main interface. That frame will stay in the framebuffer until you replace it with another, allowing you to record it, edit it, or whatever you like. >> There is an option for an output to tape directly from the card. This is probably a real-time, vga-to-ntsc type converter, as apposed to a true framebuffer. Although, with some slick programming I wouldn't doubt that it would be possibly to split the memory on the card and allocate, say 2mb for display and 1mb-2mb for framebuffering. The targa+64 is programmable to do something like that, where it has the function of 2 32-bit framebuffers on board (each with 1mb of memory). FWIW.

Dennis, It's a great board! 1024x768x24bit display and 60M WinMarks are nothing to sneeze at (and no "monkey business" involved getting the WinMarks high). With the added "Z-buffer" you can get the realtime rendering in ACAD. I'm going to talk to the MGA Manager this week about the expected capabilities for 3DS users. I think they maybe trying to the whole "ball of wax" where I think if they simply provided a DynaView "pop-up" like in ACAD … we'd go for the board en'mass Ang
#55327From: Dennis FenskeAug 29, 1993 2:36 PM
Ang; The Matrox MGA sounds like a great board. Dennis
#55414From: John TissavaryAug 30, 1993 4:10 AM
If they pull off the Dynaview-like option, I'll sell my beloved racing motorcycle to buy one! Aargh… I hope I get some more paying jobs befor they finish the 3ds interface <g>. John Tissavary (La Luna cie)
#55459From: Angelo Guarino [DTI Inc]Aug 30, 1993 11:50 AM
JT, I just talked to Matrox this morning and they are thinking about getting something … maybe by winter. They weren't sure of the market "pull" for such an item. I told'em if they shipped a DynaView-like capability that could either be used inside 3DS _or_ shelled out to to look at atleast realtime shaded geometry, that I wouldn't put any other card in my customers systems AND that I thought 3DS people would upgrade their VGA cards just for that feature alone (the card also offer 1024×768-24bit .. at 60M WinMarks .. so this would not be the only reason). If I'm right, what we need are more people calling in and telling them that we'll buy it if they build it so that they will puch it up in the Queue. Ang

My fingers are poised over the phone as we speak <g>. BTW, what's the phone number over there? Thanks, John Tissavary (La Luna cie)

Thanks, Ang. I just read David Stinnett's depressing message (one past this one on the thread). Now I'm really motivated to call Matrox. I can't understand having a hardware rendering engine on a card and not implementing it for the number one selling 3D package around. Regards, John Tissavary (La Luna cie)
#55666From: Ana Francisca GervasAug 31, 1993 3:02 PM
Ang, If they don't see the market that can generate they are simply CRAZY or BLIND. "They weren't sure of the market "pull"??????? What I'm sure is that my money is ready to go to Matrox if they release the realtime gouraud driver for 3ds. BTW, thanks for the info, hope they have something for Santa 🙂 Ana
#55716From: David StinnettAug 31, 1993 11:23 PM
I talked to them about three weeks ago inquiring about this, and the tech support guy told me that dispite the fact that they have had "hundreds" of requests, they simply have no plans on implementing realtime shading with 3DS. I told him that I'd stick with my Chrome unless they changed this, and that I'd call back in a couple of months to see if they had reconsidered. It's a shame, because I'd like to get the MGA VLB to take advantage of the empty VLB slot in my system (the Chrome is running in an ISA slot), but I can't justify the cost. Realtime shading is a real good justification in my book.<g> David
#55893From: John TissavarySep 2, 1993 3:47 AM
It's just incomprehensible and depressing that a company with a hardware rendering engine would not write an application for the #1 selling 3D package. I'm gettin' on the horn tommorrow… John (one more of the hundreds of requests) Tissavary (La Luna cie)
