glGetActiveUniformsiv: find uniformIndices[] when Uniform Block Object contains an array of Struct Objects? [closed]
سؤال
For example,
struct A{
GLint a1;
GLint a2;
GLint a3;
};
Uniform X{
A a[8];
}x;
GLchar* uniformNames[]={"x.a"};
GLuint uniformIndices[1]={0};
Now,
glGetUniformIndices(programID, 1, &uniformNames, &uniformIndices);
-- doesn't return uniformIndices[]? I think I am making an obvious mistake which I am not able to figure out. Please help me out.

I think I got where I was going wrong, to get the indices the names had to be of the form, x.a[0], x.a[1] and so on.
However, I am not able to get the UNIFORM_ARRAY_STRIDE, if the case is something like this:
uniform X{
A a;
}x[8];
How do I find the array strides in this case? Because I am not able to populate data for all the instances of X. Please help me with that. Thanks.
