Rendering FW

A rendering framework inspired by lighthouse2. This framework uses a very similar architectural design, but was re-implemented from the ground up. The Vulkan RTX core for lighthouse2 was developed by me and the Vulkan RTX renderer in this project shares most of its code with the Vulkan RTX rendercore of lighthouse2.

Building

This project requires the following dependencies:

OpenGL, version >=3.3 for any non-Vulkan based renderers, >= 4.5 for Vulkan based renderers (for interop)
GLEW
OptiX 6.5 (included)
OptiX 7.0 (included)
GLFW 3.3
FreeImage
Vulkan-Memory-Allocator
Assimp
Embree
Cpp-Taskflow
Vulkan SDK
ImGui
tinygltf

I recommend using vcpkg as it can provide all the libraries listed above. To install the dependencies for this project, run: vcpkg install glew glfw3 freeimage vulkan-memory-allocator assimp embree3 cpp-taskflow imgui tinygltf after installing vcpkg. This project has only been tested on 64 bit platforms. You may be able to get certain renderers working on 32 bit architectures but it is not guarenteed.

Features

Overall performance-oriented renderers
gLTF with animations
Anything Assimp supports including animation through file formats like Collada and FBX
Dynamic lighting, point lights, spot lights, directional lights & area lights

Available renderers:

Vulkan RTX path tracer
OptiX 6.5 RTX path tracer
OpenGL Renderer
CPU ray tracer using Embree
CPU ray tracer using custom BVH implementation (relatively fast as it uses simd packet traversal, but Embree is still a lot faster)
CUDA (non-RTX) Path tracer using custom BVH implementation

Planned renderers:

Vulkan PBR Rasterizer
