CelestiumPT 0.2: A CUDA-based Interactive Pathtracer







WORK IN PROGRESS ⚠

The library is not yet usable for external applications



CelestiumPT is a CUDA based hobby pathtracer that is being developed for learning purposes and to be suitable for realtime applications.


CelestiumPT can work on GPUs without hardware ray-tracing acceleration (tested on GTX 1650 4GB).




Building:

For now, the project can only be built via  visual studio(recommended: visual studio 2022); the .sln file is included in the project.


Dependencies:

CUDA 12.4 toolkit




Features:



Two-level acceleration structure

A-SVGF denoiser

Diffuse materials

Albedo texturing

Multiple Importance Sampling

Basic random light sampler

Solid sky

COD:Advanced Warfare style bloom

AgX tonemapping

Histogram-based auto-exposure





Plans:

The plan is to make the pathtracer somewhat closer to the kind used by Quake2RTX.


Planned features:

Metallic, glossy opaque dielectric materials

Full PBR textures input support

HDR environment map

FSR 2

Volumetrics

ReSTIR
