Bug?: sphere SOP > carve SOP

carve.toe (3.5 KB)

in the attached file I would except the carve to be “parallel” to the x axis
→ but its rotated a few degrees?

Yeah, seems to shift orientation based on the number of Columns, not very nice to work with. We’ll see about improving it (its probably been like this forever).

I just bumped into this bug today when trying to make quarter-capsule shapes and need to merge a piece of a sphere with a piece of a tube, but I can’t get the carve sop to perfectly align with the x and z axis. Is there a workaround?

edit: Found a workaround: make a tube, followed by a rounded cap and then carve it.

edit again: workaround failed, adding a cap to a tube also produces a bug, where the U coordinates are offset from the original center:

The issue here is that the Sphere SOP (mesh mode) does not begin U=0 on the axis, but one step rotation later.

One workaround would be to append a Transform SOP after the Carve SOP, and set the Rotate Y parameter to:

-360/op('sphere1').par.cols

We’ll look into making the starting point of the Mesh Sphere SOP align with the axis.

Cheers.
