Rust Constructive Solid Geometry

Rust CSG

WARNING UNDER DEVELOPMENT. Don't use this library just yet. It has a bug that is being rooted out.

Constructive Solid Geometry in Rust. Create 2D and/or 3D objects using nothing but Rust code. Combine boolean operations like union, subtraction and intersection.

This library started as a port of pycsg. With added operations for 2D objects.

The Csg structure

The rscsg::dim3::Csg consists of vertices bound together to form polygons.

The struct has basic transformations; translate, rotate and scale.

Sample

execute the real time OpenGL sample with:

cargo run --example gl

Roadmap

• Basic 3D CSG.
• Basic 2D CSG.
• Real time 3D sample.
• 2D to 3D extractions.
• Add shared date component to CSG obejcts.
• Export to known format(s).

rscsg's Issues

Holes in shapes after CSG operation

Something has gone wrong after porting the source code of pycsg.

When combining shapes with CSG operations, the resulting shapes often have missing polygons. As I'm not an expert on the subject. I'm having a hard time finding the bug.

I've created a example which easily can reproduce the error. Run the example like this:

cargo run --example gl

If anyone in the open source community has the possibility to look at the bug I'm very grateful. And don't hesitate to ask me for help.
