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. WebBlinn term = H ⇀ · N ⇀ s. The angle between the half-angle vector and the normal is always less than 90 degrees. So the Blinn specular model produces similar results to the …
