Tīmeklis2024. gada 14. aug. · This is why random number algorithms are technically called "pseudo-random number" generators (PRNG). They take an input and generate an output based on that input. The trick with PRNGs is that they generate output that (theoretically) is not predictable from the input. Outside of hardware-based random …

Tīmeklis2024. gada 18. maijs · 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. nelsons eye cape townnelson services companyTīmeklis2024. gada 19. dec. · Однако, GLSL не разрешает рекурсивные вызовы функций в любом виде, поэтому приходится развернуть наш алгоритм так, чтобы он работал итеративно. ...
