Does a convex hull modifier work on a cylinder collision?

[Leadwerks]

Does the Newton convex hull modifier work with a cylinder collision shape?

[JernejL]

AFAIK Only convex hulls, but you can build a convex hull shaped like a cylinder.

[Julio Jerez]

yes convex hull modiers works on cylinder. they work on all convex shapes (spheres, cylinder, boxes, cones etc)

That's new info to me, why did it say everywhere it only works on convex hulls? O_O

[Julio Jerez]

Because I keep calling convex hull to all other convex collision shapes.

the reason is that cylinders, spheres, cubes, ect are special case of convex hulls is because the collision can be calculation from a close from formulee.
bacuse of that they provide arbitratlly smooth behaviuor that can not be achived if we making convex hull by decretizing them into polygons, other than that they are continuestlly smooth convex hulls.

Does it work on compound convex hull shapes? Everything except a collision tree?

Last time I have test here, yes it working good and normally.
