Spark Renderer

Spark is an experimental 3D renderer built with Vulkan, aimed at finding a balance between real-time performance and high-quality rendering. It serves as a test bed for experimenting with modern rendering techniques.

Purpose

Spark is a renderer and testbed for prototyping and implementing new graphics techniques without rebuilding core systems from scratch.

Core Features

• Mix of Raytraced and Rasterised Rendering
• Reservoir-based SpatioTemporal Importance Resampling - Direct Illumination (ReSTIR DI) for efficient ray-traced shadows

Global Illumination

• Probe-based Dynamic Diffuse Global Illumination (DDGI) — real-time indirect lighting via raytraced irradiance probes
• DDGI Resampling — Efficient blending of ReSTIR DI and DDGI for more accurate indirect illumination

Neural Rendering Features

• Nvidia Ray Reconstruction — Real-time Neueal Denoiser

Screen-Space Effects

• Screen-space ambient occlusion (SSAO)
• Screen-space global illumination (SSGI)

Material System

• Physically-based rendering (PBR) workflow
• Metallic-roughness material model
