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. Webround returns a value equal to the nearest integer to x. The fraction 0.5 will round in a direction chosen by the implementation, presumably the direction that is fastest. This includes the possibility that round(x) returns the same value as roundEven (x) for all values of x. Version Support. OpenGL Shading Language Version ...
