On The Bubble
PROJECT SUMMARY
Goal:
Create a cross-platform (PC, PS5) custom engine for a Monkey Ball successor game. The engine should support path-tracing as well as custom physics and a level editor.
Time Bounds:
1 year
Team Size:
11 programmers, 3 graphics programmers, one DX12 programmer.
My Role:
Graphics Programmer
Steam Link:
My Contribution:

- NEE and Russian Roulette Implementation.
- Stochastic PBR with GLTFs materials.
- Temporal Reprojection.
- SVGF Denoising.
- ReSTIR DI.
- Transform Animations.
- Ultralight UI library to graphics connection.
- Cone Tracing
BEAR
- Wraps DX12 (with DXR), PS5 AGC (with PSR).
- Co-developed with Angel Angelov.
- Allows the creation of platform-agnostic rendering code.
- Speeds up the graphics development process.
- Learn more in a separate article...
Wavefront Path-Tracing
- Uses modern wavefront approach to GPU path-tracing.
- Is written fully with BEAR.
- Uses NEE to separate direct and indirect illumination.
- Uses Russian Roulette for the optimization.
- Learn more in a separate article...
GLTF based PBR
- Uses KHR extensions:
- ior
- unlit
- emissive strength
- clearcoat
- specular
- transmission
- volume
- Works with 1spp
- Handles glass, diffuse, specular, and metallic materials
Temporal Reprojection
- Uses history buffers for the accumulation.
- Checks for mesh ids, normals, and world position.
- Goes from a single check to a 2x2 then to a 3x3 filter to preserve history.
- Uses plane-based reprojection to find the position in the world for the camera.
ReSTIR DI
- Codeveloped with Angel Angelov.
- Based on the original paper.
Transform Animations
- Uses GLTF animations.
- Supports parenting, all transform animation types and channels.
Cone Tracing
- Referenced from RT Gems II chapter 20.
- Used for Mip Level selection.
- Calculates Mip based on texel density per triangle, cone width based on bounced distance, and takes normal and spread angle into account.
