Web20 de out. de 2024 · In Open GL ES 2.0, uniforms are the mechanism to supply constant data to individual shader programs. This data cannot be altered by the shaders. Setting a uniform typically involves providing one of the glUniform* methods with the upload location in the GPU along with a pointer to the data in app memory. WebOpenGL itself defines this to a degree, but the layout qualifier modifies the definition. OpenGL is very clear about how each element within a uniform block is laid out. Floating-point values are just the C++ representation of floats, so you can copy them directly from objects like glm::vec4.
