setUniformiv( name, list)
- Sets a uniform integer vec2 or vec3 or vec4 variable that is being passed to the Vertex or Fragment program
name:
- Type: string
- your name for the uniform integer vec
- Type: List [ integer ]
- vec2 list: [2, 5]
- vec3 list: [0, 4, 1]
- vec4 list: [1, 0, 8, 1]
Note:
- Shaders work with Viewport Shading GLSL and Viewport Shading Multitexture.
- Shaders don't work with Viewport Shading Singletexture.
