Research / Toy Renderer
Building Renderer requires the following:
- Windows 11
- CMake 3.28
The steps for Visual Studio 2022 are:
- Clone the repository:
git clone https://github.com/rtryan98/renderer.git --recurse-submodules --shallow-submodules. - Call CMake inside the cloned repository:
cmake -B build -G "Visual Studio 17 2022". - Open the solution file:
cmake --open build. - Build the project inside Visual Studio.
Windows 10 and older Visual Studio versions are not tested and may not work. Build was tested using MSVC via both cl.exe and clang-cl.exe.
- Inverse Fast-Fourier-Transform (IFFT) based ocean surface simulation:
- Utilizes oceanographic spectra presented in C. Horvath's 'Empirical directional wave spectra for computer graphics'.
- The synthesized spectra are packed together to halve the amount of IFFTs required and thus double the performance of the simulation.
- Physically based rendering:
- Implemented microfacet BRDFs:
- Cook-Torrance.
- Image based lighting (IBL).
- Implemented microfacet BRDFs:
- Tone mapping:
- Implementation of GT7 tone mapping operator as presented in 'Driving Toward Reality: Physically Based Tone Mapping and Perceptual Fidelity in Gran Turismo 7'.
- Parallelized asset baking into runtime format.
- Pipeline and shader runtime precompilation and hot reloading (F5).
- Simple resource barrier tracking for single-queue use.
- Wide color gamut (WCG) and High dynamic range (HDR) display support (via PQ inverse EOTF).
