Could you say what sources you used when making csg.js? I see that some of it looks like O'Rourke (Computation Geometry in C). But the BSP-based booleans still remain largely...

2D booleans are an absolute mess.

## Expected Behavior Reasonable retention of precision. ## Actual Behavior Some of these numbers are off by 4 times EPS!!! ```javascript [ [ 2.999997997037038, 1.499998998518519 ], [ 3.999997329382717, 1.499998998518519 ],...

## Expected Behavior That's the really odd part, if you think about what reverse would do, that is what you would get. It's a really bad idea to have such...

## Expected Behavior You're going to hate this as I haven't found one that fails under jscad! None the less, you really should take a look at the original Earcut...

"subtract" gives bad output.

## Expected Behavior ## Actual Behavior Meshlab reports 12 non manifold vertices 64 faces over non manifold edges. (I've seen this several times, here's a simple example.) ## Steps to...

3D Primitives cylinder improvements

The CSharpCAD version of cylinder which used cylinderElliptic, was already about 10% faster than JSCAD. My new version of cylinder is 10x faster. It uses extrudeSimple, which we discussed in...

Problems with use of Math.Floor and with comparisons of inexact data.

## General Bug Report I recently experiment with making my CSharp port of JSCAD using single precision arithmetic. (This was in hopes of using some special Microsoft features that would...
