Summary: GLSL built-in exp function not functioning correctly
Product: Mesa
Version: 6.5
Platform: All
OS/Version: All
Status: NEW
Severity: major
Priority: medium
Component: Mesa core
AssignedTo: [email protected]
ReportedBy: [EMAIL PROTECTED]
The GLSL exponential function does not generate the correct result. Symptom -
shader working on NV does not perform same on OSMESA. The following line:
float f = exp(-k*gl_FogFragCoord);
was replaced with:
float f = pow(2.718281828, -k*gl_FogFragCoord);
After making the replacement, the shader performed correctly again.
Test codes have verified this problem.
