#loryruta's voxelizer (3d Model to Octree)
raven raft
Hello!
Many many years ago I found myself struggling with 3d Conservative Rasterization in order to create a tool that converted a 3d Model to a Minecraft schematic (subsection of the Minecraft world). After years I've not (completely) accomplished the task but I found out there were much useful code that I could modularize. This is a piece of it: a 3d Conservative Rasterizer + Octree Construction/Traversal algorithms written in modern OpenGL. Shaders are embedded within the executable using shinji, a CMake utility of mine.

no screenshots smh 😄

It's possible to use it as a tool or as a library 🤷♂️ And yes, the API is a little bit too verbose (or awful) but please mind me, it's the first version (a little bit rushed also 😅 )...

no screenshots smh 😄
uh? There's a screenshot

its very possible that i'm blind 😮

the readme has none

oh
raven raft
the other one is a CMake utility, yeah it's confusing linking two github repos
raven raft
as you can see I'm currently dealing with rgba textures 😅
but yeah, it still gives the idea

I am trying out voxelization too currently and I think you can preserve detail with those small triangle areas by using conservative rasterization. It's pretty easy to do in geometry shader

I’m already doing conservative rasterization in the geometry shader! I project the triangles over the axis that maximises its area

That's not conservative rasterization. I meant this thing. #opengl message.
For example currently if a triangle is smaller than a pixel it will not generate any fragments/voxels which will be fixed by "enabling" conservative raster. And the missing voxels in the screenshot I sent should be filled too.
