Custom Shaders

The PlayCanvas Engine supports custom shaders for Gaussian Splats, allowing you to create advanced visual effects and customize the rendering behavior beyond the standard implementation.

Examples

Here are some examples demonstrating different custom shader techniques:

Animation Effects

Simple Sinusoidal Animation - Applies a simple shader to animate Gaussian color and position using a sine wave. This example demonstrates how to create dynamic, procedural motion effects by modifying splat properties in real-time.

Transition Effects

3D Gaussian Splat Statues - Uses custom shaders to transition splats on and off screen via a hot, plasma-type effect. This showcases how custom shaders can create dramatic visual transitions and material effects.

Lighting and Relighting

3DGS with Physics and Relighting - Uses custom shaders to relight a splat to implement a night mode with multiple moving point light sources. This example demonstrates advanced lighting techniques and how to dynamically modify splat appearance based on scene lighting conditions.
