Update:
After some more testing, I found out that varying parameters are not passed
correctly between the vertex and fragment shaders. Using the following vertex
shader:
uniform mat4 MV;
uniform mat4 MVP;
uniform mat3 N;
varying vec3 blue;
varying vec3 green;
void main() {
gl_PointSize = 1;
gl_Position = MVP * gl_Vertex;
blue = vec3(0, 0, 1, 1);
green = vec3(0, 1, 0, 1);
}
and fragment shader:
varying vec3 blue;
varying vec3 green;
void main() {
gl_FragColor = vec4(green, 1);
}
I see everything rendered blue, NOT green. If I do
gl_FragColor = vec4(blue, 1);
I see nothing, i.e. a black screen.
Additionally, using the software renderer, everything works.
