gsdf

Offshoot from this project. Is WIP.

Features

Heapless algorithms for everything. No usage of GC in happy path.
Generate visualization for your parts as shaders.
Heapless Octree triangle renderer. Is stupid fast.
GPU and CPU implementations for all shapes and operations. CPU implementations are actually faster for simple parts.
- Design your part using one API, switch between CPU and GPU after design.
Extremely coherent API design.

Part design - NPT Flange example.

This was converted from the original example. See README for images.

    const (
		tlen             = 18. / 25.4 // thread length
		internalDiameter = 1.5 / 2.
		flangeH          = 7. / 25.4
		flangeD          = 60. / 25.4
	)
	var (
		npt    threads.NPT
		flange glbuild.Shader3D
		err    error
	)
	err = npt.SetFromNominal(1.0 / 2.0)
	if err != nil {
		return nil, err
	}
	pipe, err := threads.Nut(threads.NutParms{
		Thread: npt,
		Style:  threads.NutCircular,
	})
	if err != nil {
		return nil, err
	}
	flange, err = gsdf.NewCylinder(flangeD/2, flangeH, flangeH/8)
	if err != nil {
		return nil, err
	}
	flange = gsdf.Translate(flange, 0, 0, -tlen/2)
	flange = gsdf.SmoothUnion(pipe, flange, 0.2)
	hole, err := gsdf.NewCylinder(internalDiameter/2, 4*flangeH, 0)
	if err != nil {
		return nil, err
	}
	flange = gsdf.Difference(flange, hole) // Make through-hole in flange bottom
	flange = gsdf.Scale(flange, 25.4)      // convert to millimeters
	renderSDF(flange)
