Bahasa Indonesia - Tiếng Việt - 日本語 - 中文版 - 한국어 - Español - Portugues - Français - Italiano - Deutsch - Русский - Polski - English So far we have seen how the GPU manages large numbers of parallel threads, each one responsible for assigning the color to a fraction of the total image. Although each parallel thread is blind to the others, we need to be able to send some inputs from the CPU to all the threads. Because of the architecture of the graphics card those inputs are going to be equal (uniform) to all the threads and necessarily set as read only. In other words, each thread receives the same data which it can read but cannot change. These inputs are called uniform and come in most of the supported types: float, vec2, vec3, vec4, mat2, mat3, mat4, sampler2D and samplerCube. Uniforms are defined with the corresponding type at the top of the shader right after assigning the default floating point precision. You can picture the uniforms like little bridges between the CPU and the GPU
