vertexshadern

A vertex shader is a type of shader used in 3D computer graphics to determine the final position of each vertex in a 3D model. It is a small program written in a high-level shading language, such as GLSL (OpenGL Shading Language) or HLSL (High-Level Shading Language), and is executed on the GPU (Graphics Processing Unit) for each vertex in a 3D model. The vertex shader takes as input the original position of the vertex, along with other attributes such as color, texture coordinates, and normals, and outputs the final position of the vertex in screen space, along with any other attributes that will be interpolated across the surface of the 3D model. Vertex shaders are an essential component of modern 3D graphics, allowing for complex lighting, shading, and animation effects to be applied to 3D models in real-time. They are typically used in conjunction with fragment shaders, which determine the final color of each pixel on the screen.
