Crate csgrs

A fast, optionally multithreaded Constructive Solid Geometry (CSG) library, built around Boolean operations (union, difference, intersection, xor) on sets of polygons stored in BSP trees.

Features

Default

• f64: use f64 as Real
• stl-io: .stl import/export
• dxf-io: .dxf import/export
• chull-io: convex hull and minkowski sum
• metaballs: enables a CSG implementation of metaballs
• hashmap: enables use of hashbrown for slice, related helper functions, and is_manifold
• sdf: signed distance fields (sdf) using fast-surface-nets
• offset: use geo-buf for offset operations
• delaunay: use geos spade feature for triangulation

Optional

• f32: use f32 as Real, this conflicts with f64
• parallel: use rayon for multithreading
• svg-io: create CSGs from and convert CSGs to SVG’s
• truetype-text: create CSGs using TrueType fonts .ttf
• hershey-text: create CSGs using Hershey fonts (.jhf)
• image-io: make 2d CSGs from images
• earcut: use geos earcutr feature for triangulation
• bevymesh: for conversion to a bevy Mesh

Modules

bsp

This module contains the implementation of the BSP tree data structure

convex_hull

The convex hull of a shape is the smallest convex set that contains it. It may be visualized as the shape enclosed by a rubber band stretched around the subset.
