Re: GR_CLIP_COORDS Inverted Axis

Posted on 2024-03-10, 22:04

Hi Dege, I put together a quick demo scene for you and tested it (working) on a Voodoo 2. Attached it to this post. Hopefully you are able to log the Glide calls and notice something interesting, because it would be difficult for me to extract the code needed for a minimal repro. I'm still not 100% …

Re: Glide Games and ALT + TAB (Multitasking) Support

I ended up throwing in the towel on this. I tried quite a few different things but as far as I can tell there just isn't a good workaround. I ended up just disabling task switching for Glide mode and called it a day. There's an old Microsoft KB on how to do this - Q226359. On Windows 9x it's pretty …

Glide Games and ALT + TAB (Multitasking) Support

Hi all, I've been writing a Glide backend for my game and I noticed the Voodoo cards don't really handle multitasking very well. It always freezes for me when tabbing back in. I've tried totally closing the glide context and re-initializing everything (uploading textures again etc) but it never …

GR_CLIP_COORDS Inverted Axis

Posted on 2024-02-15, 03:01

Hi there, Not sure if bug reports are welcome here, if not please feel free to disregard. I noticed a problem with dgvoodoo which I believe has to do with the use of homogeneous coordinates in Glide 3.x. I grabbed the latest version from github. Basically the Y axis gets flipped, not really sure why …

Re: AMD 3DNow! Documentation

Anything of use in the k6-2+ datasheet? https://www.amd.com/system/files/TechDocs/23542a.pdf Thanks! Most 3DNow instructions are just early variants (designed to work with MMX registers) of integer instructions that were later included in SSE or SSE2. If you know SSE it should be easy enough to …

Any help from 3dmark? They advertised support for these instructions. Hmm, probably not - unless the source is available for the tool. Although one of the pdfs in the archive RetroGamer posted is very helpful, was almost exactly what I was looking for. "3DNow! Instruction Porting Guide" from August …

Interesting question, whatcha tryin to do? :-) I'm working on a game engine with Windows 9x support. For some critical routines I'm also writing SSE implementations and the SSE instructions are very well documented online. For example, culing a leaf in the BSP tree with an AABB test is something …

The only official thing left is the manual for SimNow, an ancient piece of development software that used it, with the Athlon/Opteron 64-bit CPUs. https://developer.amd.com/wordpress/media/2012/10/SimNowUsersManual4.6.1.pdf And there are some archived materials here..... https://kib.kiev.ua/x86docs …

AMD 3DNow! Documentation

Posted on 2022-07-28, 12:46

in Milliways
Hi there, I was wondering if anyone knew of any additional documentation for the 3DNow! instruction set (or analysis). I've found the official documentation published by AMD (https://www.amd.com/system/files/TechDocs/21928.pdf) but was wondering if anything else was floating around out there. They …

Re: MiniGL Specification

Posted on 2022-02-22, 19:57

in Windows
There might be some useful info here: https://fabiensanglard.net/3dfx_sst1/ MINIGL "STANDARD" Even though MiniGL was a subset of the OpenGL 1.1 standard, there was never a spec for it. MiniGL was "whatever functions Quake uses". Utility objdump running against quake.exe binary makes it easy to …
