renderöintipolun

Renderöintipolku, often translated as rendering pipeline or render path, refers to the series of steps a graphics processing unit (GPU) takes to transform 3D scene data into a 2D image displayed on a screen. This process is fundamental to computer graphics and real-time rendering, such as in video games and simulations.

The pipeline typically begins with the application stage, where the CPU prepares geometry data and issues drawing commands. This data then enters the GPU's graphics pipeline. The geometry stage involves processing the vertices of the 3D models, including transformations and lighting calculations. Following this is the rasterization stage, where the GPU converts the geometric primitives (like triangles) into pixels, determining which pixels are covered by each object.

The fragment processing stage then occurs, where the color of each pixel is determined. This involves texturing, per-pixel lighting, and other shading effects. Finally, the output merger stage handles tasks like depth testing (ensuring objects closer to the viewer obscure those further away), stencil testing, and blending to produce the final color for each pixel before it is written to the framebuffer, which ultimately becomes the image displayed on the monitor. Different rendering techniques and hardware architectures can lead to variations in the exact stages and their order, but the core concept of a sequential processing path remains consistent.
