Purpose

Testing performance of adjusting which slicing plane to pick while building the BSP tree in CSG.js

How to test

git clone https://github.com/AllwineDesigns/csgjs_test.git
cd csgjs_test
npm install
cp trees.js node_modules/@jscad/csg/src/trees.js
src/stl_boolean.js -a stl/torus.stl -b stl/sphere.stl -u out.stl

Make adjustments

Change the index that is chosen on line 485 of node_modules/@jscad/csg/src/trees.js to see how it affects performance. The torus and sphere provided show the most dramatic performance improvement that I've seen, but other models often see an improvement as well.
