A shader program consists of vertex and fragment shaders. A vertex shader defines the geometric attributes of vertices, whereas fragment shader defines their color. In this post, I’ll address how to create the vertex and fragment shaders and how to use them. Vertex shader In vertex shader, w...
GLSL (OpenGL Shading Language) is a programming language for simple program, Shader, that describes the color attribute of each vertex in parallel computation. Thus, all vertices do not know the status of other vertices nearby, i.e., vertices are blind to the others. But, if we use a uniform v...
A shader material is rendered with a custom shader. It requires vertex and fragment shaders which are written in GLSL (openGL Shading Language) code and depict the position of a vertex and its color, respectively. Since these codes run on the GPU using WebGL, a ShaderMaterial is rendered prope...
