Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1.Run visualRBM on AMD GPU
2.glGetError() returns error code on glTexParameteri() calls
with last parameter = GL_CLAMP
3.

What is the expected output? What do you see instead?
Graphs tab shows lines at zero. Visible tab show no digit images.

Change all calls in \QuickBoltzmannNative\OpenGLCommon.cpp to:
glTexParameteri(GL_TEXTURE_RECTANGLE, GL_TEXTURE_WRAP_S, GL_CLAMP_TO_EDGE);
glTexParameteri(GL_TEXTURE_RECTANGLE, GL_TEXTURE_WRAP_T, GL_CLAMP_TO_EDGE);
...etc...
