vertexkäsittelyn

Vertexkäsittelyn, often translated as vertex processing, is a fundamental stage in the computer graphics rendering pipeline. It's where the geometric data of a 3D scene is transformed and prepared for display. The input to the vertex shader consists of vertices, which are points in 3D space typically defined by their coordinates. The primary task of the vertex shader is to manipulate these vertices.

During vertex processing, transformations such as translation, rotation, and scaling are applied to move objects within the scene. Furthermore, projection transformations are crucial, converting the 3D coordinates into 2D coordinates that can be displayed on a screen. This process also involves calculations for lighting, where the intensity and color of light interacting with the surfaces are determined at each vertex. The output of the vertex shader is a modified set of vertices, often with additional attributes like color, texture coordinates, and normal vectors, ready for the next stage of the rendering pipeline, which is typically rasterization. Efficient vertexkäsittely is essential for real-time graphics applications like video games and simulations.
