Grating Model Computation

Raster model computation is an image processing technique that converts continuous images into discrete pixels, dividing images into grids and mapping each grid to screen pixels. As a fundamental algorithm in computer graphics, raster model computation forms one of the foundational pillars of computer graphics implementation. The computational process involves several key stages including scan conversion (converting geometric primitives to pixel arrays), image texture mapping (applying surface patterns to 3D objects), and perspective transformation (converting 3D coordinates to 2D screen space). This algorithm typically employs mathematical approaches like Bresenham's line algorithm for efficient pixel plotting and uses interpolation methods for smooth texture mapping. The technique finds extensive applications in computer graphics systems, game development engines (for real-time rendering), and virtual reality platforms where efficient pixel manipulation is crucial for performance optimization.
