I’m using a GL_RGBA_FLOAT32_ATI texture (accessed in a vertex shader), out of which the RGB part is being used, but the A part is free for other uses. I want to calculate a normal on the CPU, and somehow pack it into that single float (A). WebMay 18, 2024 · Uniforms are intended to be set by the user from OpenGL, rather than within the shader. However, you can initialize them to a default value using standard GLSL initalizer syntax : uniform vec3 initialUniform = vec3(1.0, 0.0, 0.0); This will cause the uniform to have this vector as its value, until the user changes it.
