The goal of this project is to use the Rust language to implement a Research-Oriented rendering system. Compared with other Research-Oriented renderers, we pay more attention to software engineering and code simplicity instead of extreme performance optimization, so for those who want to enter the field of graphics, this may be a better platform.

Motivation

Modern rendering system with proper software design

There are many successful rendering systems out there, the most notable one being:

• mitsuba
• PBRT

However, Mitsuba 0.6 suffers from poor dependency selection and PBRT v4 follows problematic software design methodologies.

The Rust language offers excellent software engineering features and a complete toolchain which makes future development and maintenance more convenient.

Target

As portable as possible

We are ready to support the following platforms:

• MacOS our development platform
• Windows platforms we must support
• Linux platform we must support
• FreeBSD platform we must support
• WASM platforms we may consider supporting

Project structure

• src/ directory contains all the source files
• src/core the renderer core, basically anything related to how the image being rendered.
• src/utils containing all the utility code used by other utility folders in src/
• other dirs in src/ are featured utility used by core.
• in each folder in src/ has a tests/ folder for containing all the tests, and using the same file name as the file should be tested.
• each test function should be easy to identify (or looks like) the original function or part of the function.

for example:

// src/geometry/ray.rs
fn point_at();
// src/geometry/tests/ray.rs
fn test_point_at();
