A small tool to generate 3D planets, using native WebGPU. The goal of this tool is mainly to train myself on WebGPU, various graphics programming techniques, and procedural generation.
- clone the
glfw,glfw3webgpu,glmgit submodules to theexternalfolder - clone the
imguirepo and add to it theCMakeLists.txtfound here: https://eliemichel.github.io/LearnWebGPU/basic-3d-rendering/some-interaction/simple-gui.html#setting-up-imgui
- Procedural shape and normal generation with noise
- Post-process ocean on a ray-traced sphere
- Triplanar texture mapping
- Shadow map
- Skybox from https://tools.wwwtyro.net/space-3d/index.html
More important is on top (or not)
- add some textures ?
- would be nice to have a drag and drop to test a texture
- atmosphere
- ocean shader
- the transparency of the ocean when there's no light is ugly
- actual waves
- add a slow rotation of the planet: can give a better idea of the of the looks of the shadows
- shadows:
- how to make the shadows less "blocky" ? is there other methods to do the shadows ?
- view frustrum of the shadow rendering should change depending on the planet radius (breaks if planet too big)
- could add percentage-closer filtering
- improve the terrain edition for more "earth-like" aspect
- more variety of shapes: plateau, crests...
- less regular "wavyness" with a lot of flat parts but also some high and some deep parts ?
- add props on the surface
- trees, rocks, grass/vegetation
- compute the geometry on a compute shader ?
- add LOD
- add flight simulator
- spawn from camera
- simple collision with the mesh ?
- add a bike/car drive on the surface ?
- Improve GUI
- Show a timer of the time taken to build the planet
- show the current amount of polygons/vertices
- Get rid of the seams between faces ? (They are invisible on high res)
- Could improve the vertex normals computation (maybe not worth the hastle and computations)
