金属着色器中的数组声明

Question

It is possible to use array in GLSL like this:

float[4](.5, .5, .5, .5)

Is it possible to use arrays in metal shader, if yes how can I declare it? Thanks!

Answer 1

It works almost like in c++:

float array[3] = float[3](0.5,0.5,0.5);
float array[3] = float[3](0.5);// also works, but you can't initialize the entire array with that number, it's going to be (0.5,0.0,0.0)
