I. C0/C1/C2 Continuity for Sweep Splines (on the top bar):

1. C0: polylines, linearly interpolation

2. C1: smooth tangent, cubic spline (Catmull-Rom) -> default

3. C2: smooth second derivative (smooth reflection), cubic spline (B-Spline)

Unlike C0/C1, the spline doesn't go through the control points with C2 continuity.


II. Groove Blend

The new Groove blend mode allows you to apply Boolean operations within a certain thickness around the surface (i.e., you can use primitives to extrude the surface).

You can also add blend factor or fillet/chamfer blend to this mode.

If you only want to apply this on the intersected edges, you can add hole/shell to the primitive.

A feature request, if possible: Ambient Occlusion. It'd be great if you could give a color to the concave parts of an object. As long as there are no textures, AO would help to give more definition to MCSG objects. It would be no problem to only see this in the rendering.

AO is part of global illumination (e.g., when you only use diffuse material, you'll see the concave parts being dark)

I love the new groove blend ! one request ; would it be possible on "sweep spline" mode to scale the sphere shaped only on one axis ? right now it only scale on both axis ...

Groove Blend is really useful for adding a thick "coating" to objects, like adding a layer of fabric. Sometimes, though, I *only* want the coating but not the underlying strokes. It would be cool if I could make those strokes invisible, but at present, the only way to do this is to duplicate those strokes and then set them to Subtract.
