About this project

What does Photonics: A raytracing engine add?

Photonics: A Raytracing Mod

An Iris extension that adds voxel based raytracing to Minecraft.
With a focus on performance, Photonics is able to deliver performance comparable to that of hardware raytracing.

Shaders that support Photonics:

  • Euphoria Patches (requires 1.9.0+ and Photonics v0.3.4+)
  • Photon (requires latest from Github & Photonics v0.3.4+)
  • Eclipse (requires latest version from Github & Photonics v0.3.4)
  • Shrimple (requires latest from GIthub & Photonics v0.3.4+)

Support patched in by the photonics mod:

  • BSL (Photonics v0.3.0+ requires 10.1+, v0.2.9 or below requires 8.2.9)

Features

By using it's custom voxel raytracing, Photonics adds many visually stunning effects:

Soft Shadows

Every block casts beautiful soft shadows from block lights!
Physically accurate soft shadows

Global Illumination

Tired of how dull the world is in shadow? Worry not! Photonics adds accurate Global Illumination to shadows.
Occluded areas appear darker. Just like in real life!

3D Blocks

Using its voxel raytracing, Photonics can render 16x16x16 block models directly!
Custom Models can also be implemented using MagicaVoxel.
Resourcepacks can define their own 3D blocks!

Colored Glass Lighting

Photonics can tint the color of light that passes through glass, casting colored shadows over objects.
Glass tints light sources

Up to 20 lights per chunk

By default, traces 20 lights per chunk, with shader settings allowing you to increase that number to 100!
Have all the shadows that you want!

Notice

  • Photonics doesn't utilise Hardware Raytracing, and because Minecraft is built on OpenGL, building in Hardware Raytracing is unfortunately not possible
  • This mod is still in Alpha, bugs and compatibility issues are to be expected
  • Any mod that modifies Minecraft Rendering/Chunk loading will affect compatibility
  • MacOS is not supported!
