SnapCore and Intersect
-
Hi all,
I tried the code described in this thread: https://developers.maxon.net/forum/topic/6626/7199_r14-snap-system/10
This code inside the liquitool example work as expected.
But if i try to use SnapCore::Intersect instead SnapCore::Snap, to get the normal at point, this code don't work.This is the line that I changed to:
if (snap->Intersect(pos, norm, false, res)) instead if (snap->Snap(pos, res))Seem that the intersection don't work anymore.
Any help?
Thanks in advance

DrawViews(DRAWFLAGS_ONLY_ACTIVE_VIEW|DRAWFLAGS_NO_THREAD|DRAWFLAGS_NO_ANIMATION); // Update viewport } win->MouseDragEnd(); // Reset viewport status EventAdd();

Seem that the normal is returned by SnapCore::Snap in SnapResult::mat.v2. I'm verifying

Hi @RenatoT, I don't think there is an issue,
just in case Intersect is supposed to work only for guide and spline see Modeling Settings - Intersection Snap. So maybe you are looking for GeRayCollider::Interesct.

Hi Maxime. Thanks for reply. At last I used the BVHTree for that.
