VulkanRenderer
Installation
To run this project yourself, simply download the source code from GitHub, as well as the latest Vulkan SDK here: https://vulkan.lunarg.com/sdk/home. The solution will automatically try to find the Vulkan SDK installation by its environment variable VULKAN_SDK. Last tested with Vulkan SDK version 1.3.275.0.
! NOTE ! The Release build currently experiences irregular crashes at startup or shutdown, which I am investigating. Could be related to timeline semaphores.
Project
This is my study project, starting from September 2023, for a whole semester. The goal is to utilize the Vulkan graphics API to create a renderer that creates realistic and stunning real-time renders of cars and other objects with clear-coat pbr materials, utilizing raytraced shadows and reflections, rasterization will be used for everything else. This project uses the following Vulkan extensions:
- Vulkan EXT dynamic rendering
- Vulkan EXT descriptor buffer
- Vulkan EXT timeline semaphores
Current features
- Physically-based rendering
- Lambertian/Burley/Oren-Nayar Diffuse BRDF
- Clear-coat materials
- Normal mapping
- Image-based lighting
- Generated BRDF LUT
- Generates from equirectangular to cubemaps
- Energy conserving indirect specular (works for clear-coat specular too)
- Basic post-processing (Tonemap, gamma correction, exposure)
PBR Chess scene, with image-based lighting
Toy car with clear-coat enabled
Toy car with clear-coat disabled
Energy conservation in indirect specular (works for clear-coat specular too) - White Furnace Test
Indirect_Specular_Clear_Coat_Energy_Conservation_White_Furnace_Test.mp4
Planned features
- Raytraced soft shadows
- Raytraced reflections
- Raytraced ambient occlusion
Stretch features
- (Convolution) Bloom
- Dithering
- LODding
- Mesh shaders (and meshlet builder)
