Pathfinder - my toy RHI-agnostic GPU-driven bindless renderer that I'm building to learn graphics and the latest GPU features.

Progress.

• UE4 PBR shading model. Forward+ gpu-driven mesh-shading, reversed Z. Tone-Mapping + Gamma-Correction + SSAO + Bloom + HDR(RGBA16F). As you see I'm completely GPU-bound, 99% load, RTX 3050 Ti laptop kinda weak :(

Features

• glTF model loading.
• Highly utilized ReBAR usage.
• RenderGraph based.
• RHI-agnostic (currently built with Vulkan 1.3 and BDA)
• ECS, scenes system.
• Compute Tiled Light Culling + 2.5D
• PBR HDR Renderer
• Post-processing (Bloom, SSAO)
• Texture compression(BC1-BC7)
• Mesh-Shading(everything is drawn in 1 multi draw indirect call)
• Rapid 2D Batch-Rendering(requires no VRAM).
• Compute Object Culling(gpu-driven)
• ImGui
• Cascaded Shadow Mapping(WIP)
• DebugRenderer(spheres, cones, aabbs, lines, etc..)
• Bindless(descriptor set per frame for images and textures, buffers are used in shaders through BDA)
• Multithreaded pipeline building via efficient C++23 threadpool.
