Camellia is a pathtracer shader for Minecraft. It's my take on Quad Raytracing in Minecraft, using the state of the art techniques from the H-PLOC paper to build a BVH directly on the GPU. While I tried my best, performance is still suboptimal and not yet suitable for real-time gameplay. Camellia is intended for research, experimentation, and learning. It may also straight up not work on AMD. I don't have an AMD card to test it with, sorry!

Camellia in-game preview

Features

  • Reference pathracer with spectral-like caustics and DOF.
  • QuadRT allows all geometry to be captured and traced correctly, unlike traditional voxel raytracing which compromises with hardcoded models.
  • Supports all kinds of blocks, including custom models, entities and players.
  • Probably very good mod support, not fully tested.

BVH debug

Requirements

  • Minecraft with Iris installed.
  • A GPU and driver supporting GLSL 460, compute shaders, SSBOs, custom images, and GL_KHR_shader_subgroup_*.
  • NVIDIA is fully tested (on a 5080), while AMD and Intel are best-effort targets and are not tested.

Installation

  1. Download the repository ZIP or from Modrinth and extract it.
  2. Place the extracted Camellia folder in .minecraft/shaderpacks/. The pack folder should contain a shaders/ directory.
  3. Select Camellia in Iris's Shader Packs menu.
