GodotGpuConwaysLife

This project is an implementation of a growing forest, inspired by Conways Life, running on a fragment shader

Tested with Godot 3.5-stable

Constrains

• using only GLES2 features to allow web/mobile operation
• gdsript only (no custom modules needed)

Main principle

• There are two Viewports (Front and Back)
• Each is containing a sprite, which displays the viewport-texture of the opposite VP.
• That way, the shader can read the texture of previous frame for current frame. (with 1 frame delay)
