Tinyrenderer is a C++ library designed as an educational tool for building a 3D graphics pipeline from scratch. It provides a software-defined rendering environment that executes all geometric transformations and rasterization tasks on the central processor, intentionally avoiding reliance on external hardware acceleration or graphics libraries.
The project serves as a pedagogical resource for understanding the fundamental mathematical principles of computer graphics. It enables users to implement custom shader pipelines and core rendering techniques, such as barycentric coordinate calculation, depth buffering, and coordinate projection, to transform 3D models into 2D pixel buffers.
Beyond basic rasterization, the library covers a broad range of advanced rendering capabilities. These include surface illumination simulation, texture mapping, and visibility resolution through techniques like back-face culling and z-buffering. It also supports complex visual effects such as normal mapping, ambient occlusion, and various shadow rendering methods, allowing for the creation of detailed 3D environments within a custom-built software framework.
