Tinyrenderer
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.
Features
- Depth Buffers - The renderer tracks the depth of each pixel during rendering and discards fragments that are obscured by previously drawn surfaces to ensure accurate hidden surface removal.
- Software Renderers - Executes the entire graphics sequence on the central processor without relying on external hardware acceleration or graphics libraries.
- Software Rasterizers - Implements a complete software-based 3D graphics pipeline that performs all geometric transformations and rasterization on the CPU.
- 3D Graphics Pipelines - Implements a complete software-based 3D graphics pipeline for rendering geometry.
