Summary: Simple Pixel Shader not working
Product: Mesa
Version: 6.5
Platform: PC
OS/Version: Windows XP
Status: NEW
Severity: normal
Priority: P2
Component: Mesa core
AssignedTo: [email protected]
ReportedBy: [EMAIL PROTECTED]
Please take a look at this example:
http://maddimax.dyndns.org/~maddi/mesabugsample.rar
The pixel shader just looks up the Texture and replaces the red channel with
1.0. With the current cvs version ( I updated today ), the whole thing breaks in
_slang_library_tex2d, because 1. the swrast->TextureSample[] are all zero, and
second, because the parameter "unit" is some invalid value ( 0xe6...... or
something like that )
