http://bugs.winehq.org/show_bug.cgi?id=9888 --- Comment #9 from H. Verbeet <hverbeet(a)gmail.com> 2007-10-20 01:09:16 --- It appears to me you're missing some background information, and misunderstood my comment #5 and its logical conclusion, comment #7. The first step is understanding what PS 1.1 actually means. MSDN has some information on that topic: http://msdn2.microsoft.com/en-us/library/bb219842.aspx http://msdn2.microsoft.com/en-us/library/bb219851.aspx http://msdn2.microsoft.com/en-us/library/bb172917.aspx http://msdn2.microsoft.com/en-us/library/bb219849.aspx What wined3d has to do is map that Direct3D functionality to equivalent OpenGL functionality. The direct equivalents of Direct3D pixel shaders in OpenGL are fragment programs and GLSL fragment shaders: http://www.opengl.org/registry/specs/ARB/fragment_program.txt http://www.opengl.org/registry/specs/ARB/fragment_shader.txt http://www.opengl.org/registry/doc/GLSLangSpec.Full.1.20.8.pdf If either of those is present wined3d can currently use that to implement support for Direct3D pixel shaders. Unfortunately, as you can see at http://www.delphi3d.net/hardware/extsupport.php?extension=GL_ARB_fragment_pr... and http://www.delphi3d.net/hardware/extsupport.php?extension=GL_ARB_fragment_sh..., your graphics card supports neither of those. You can also verify this by looking at the output of "glxinfo". However, the register combiners OpenGL extensions provides much of the functionality that PS 1.1 provides, (http://www.opengl.org/registry/specs/NV/register_combiners.txt & http://www.opengl.org/registry/specs/NV/register_combiners2.txt) and these extension are supported by your graphics card: http://www.delphi3d.net/hardware/extsupport.php?extension=GL_NV_register_com... http://www.delphi3d.net/hardware/extsupport.php?extension=GL_NV_register_com... The problem is that because the interface provided by register combiners is quite different from the one provided by Direct3D pixel shaders, it will take a significant amount of work to implement pixel shaders on top of register combiners within wined3d. This makes it somewhat unlikely anyone will implements this anytime soon. -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching all bug changes.
