Mesh.Prism
Rounded prism configuration module.
type spec = {
}
Rounded prism joint and curvature specification.
In general, joint_
parameters are pairs determine the distance away from the edge that curvature begins, and k
parameters set the smoothness of the curvature.
type holes = [
| `Same | (* the outer path |
| `Flip | (* the outer path |
| `Spec of spec | (* one |
| `Mix of [ `Spec of spec | `Flip | `Same ] list |
]
Specifies how holes in the prism should be treated, either relative to the outer shape, or independantly. When multiple holes are present, `Mix
allows each one to be specified separately, to treat all the same, use the other variants directly. Defaults to `Flip
for the prism
and linear_prism
functions.
flip spec
Negate the top and bottom inwards joints (firsts of the joint_bot
and joint_top
pairs) of caps
. These values govern whether the roundover flare inwards (positive when shape is CCW) or outwards (negative when shape is CCW). Since holes (inner paths) have reverse winding compared the outer path, you'll often want to use opposite polarity inward joints.
