Question

I have a GLSL shader program running my iPhone app (it’s a very very simple shader). I am trying to declare an array of vec2 but I’m having a lot of trouble. My shader is wrapped in a thrid party library, so unfortunately I can’t get any real information about the actual error in syntax is.

My code (not working) to declare an array of vec2 is:

highp vec2 steps[5] = vec2[](
                            vec2(   0.0015625,  0.00208333333333),
                            vec2(    0.003125,  0.00416666666667),
                            vec2(     0.00625,  0.00833333333333),
                            vec2(      0.0125,  0.0166666666667),
                            vec2(       0.025,  0.0333333333333)
                            );

Does anyone have any idea how to create an array of vec2 datatypes in OpenGLES 2.0?

Answer 1

highp vec2 steps[5] = {
                            vec2(   0.0015625,  0.00208333333333),
                            vec2(    0.003125,  0.00416666666667),
                            vec2(     0.00625,  0.00833333333333),
                            vec2(      0.0125,  0.0166666666667),
                            vec2(       0.025,  0.0333333333333)
                            };
