The Glide 3.0 is not - compatible with the Glide 2.x so it doesn't work with the current - version of the driver; - - - Visual C++ 5.0 is only compiler test but others should be ok with - changes to the makefiles (CFLAGS/LFLAGS). - - - DirectX 6 SDK (was a MS download but not sure if still available). - - - SoftIce or another debugger that will get DPF's is nice. - - -Tested on: ----------- - Windows 95 - Windows 98 - Windows NT 5.0 (beta 2) - - -What is able to do ? --------------------- - - - the driver will try and use DirectX to rasterize the OpenGL primitives - that are sent to the driver. The driver will fall back to SW if the rendering - context is too big. The fallback to SW still uses DirectDraw. If the driver - fails to support and operation (accum, stencil, etc) then it will try and get - Mesa to render it in SW. DirectX 6 features that are unsupported by the - installed DirectX 6 driver will be mapped to some other best fit feature. - - -How to compile: ---------------- - - These instructions assume you have Visual C++ installed. - - You might need to increase you enviroment space. You can do this by - adding the following statement to you config.sys. - - shell=C:\COMMAND.COM C:\ /p /e:8198 - - Next setup you compiler enviroment by running vcvars32.bat in the Visual C++ - 'bin' directoy. - - c:\DevStudio\VC\bin\vcvars32.bat - - Modify the D3D makefile to point at your SDK install. Example has the SDK - installed on my 'f' drive in the root. - - file: \Mesa-3.0\src\makefile.d3d - - SDKROOT=f:\mssdk - - Now you can simply make the project. If you look in the makefile you can see - I have some different targets like 'install'. - - nmake /f makefile.d3d - - -FAQ: ----- - - 1) I don't think the driver is using my DirectX driver. - - This maybe true as the current version will only select the Primary D3D driver - installed. If you 3D card is the secondary (3dfx) then your out of luck for this - release. - - 2) The driver seems like its not HW accelerated. - - If you have a video card with limited memory then you might want to try and - change your destop resolution to a low setting (640x480x16) so that the 3D part - of the card has more resources. Remeber the driver can't make the card better... - - 3) Nothing works. - - Make sure you have a DirectX '6' driver installed. Check you driver docs for this - info or use the SDK info utilities. - The final 'dll' is named opengl32.dll and is either in the same directory as the - OpenGL program or in your system directory (x:\windows\system or x:\winnt\system32). - Check your destop resolution. Most DirectX 6 drivers will only support 16bit and - 32bit color depth. To find out for sure you can check the DirectX Info Viewer in - the SDK. - - - 4) Rendering doesn't look right. - - Sometimes this is because the card doesn't support a feature that that is required. - This is usually due to unsupported alpha functions (test/blend) or texture mapping. - Some cards suffer from too small of an alpha channel. The driver does its best to - fallback on unsupported features. This is not to say the driver may not have a bug(s). - - 5) Textures look bad. - - No mipmapping in this release. - - -Thanks to: ----------- - -Brian Paul - - - - -Leigh McRae (leigh@altsoftware.com) -February 9, 1999 - |
