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. WebUsing vec3 seems ideal because it would theoretically save a lot of memory. But perhaps that temporary vec4 (position,1.0f); costs some runtime performance at the savings of memory. I'd imagine creating a vec4 from a vec3 attribute would be a small cost, but was curious if anyone had thoughts. 10. 12. southwestern distillery cornwall
