I'm not quite sure what I'm doing wrong here, but I suspect I'm making a silly buffer error. I've got a
uniform float weights[numWeights] array in a GLSL fragment shader. I can successfully get the location, type and length in my Java code and all is good.
However I can't seem to update them properly - I'm doing:
buffer.rewind();
buffer.put(dataArray);
buffer.flip();
ARBShaderObjects.glUniform1ARB(location, buffer);Where dataArray is a float[] and buffer is a FloatBuffer. In my fragment shader I can get correct values out of my uniform array for indices 1 to numWeights-1, but weights[0] is always 0. :shock:
Is there something special about
- ? Or is my buffer tinkering somewhat off? Anyone any suggestions?
No, there's nothing special about
- . It must be something else in your code.
