godot-fake-planet-demo
a small demo which uses shaders to fake a spherical game world in Godot
online version
(wasd to move, tab to toggle the effect)
all source files are inside the src folder.
how does it work?
the world is warped around the player to make it look as if it is spherical.
if the player walks too far, they are warped to the other side.
internally, the game world is a flat plane, and is rendered as a parabola.
how do i use it?
first, set up your objects with the standard spatial material.
then, convert it to a shader, and replace that shader with the SmallWorld.gdshader included.
make sure to initialize the "warp" parameter, and to pass the player's location to the shader every frame. examples are part of the Planet script.
