Greetings,
I need to perform Greetings,
I need to perform some basic geometric calculations on my mesh. In particular I'd like to intersect a boundaryPatch with a ray and need to know the coordinates of the intersection. I know I could do it using an octTree based on a triSurface. But is there a) an easy way to convert my boundaryPatch to a triSurface or b) any function that gives me the hitPoint of a line through a patch ? I can obtain the points from primitivePatch but can't find a function to obtain a triFaceList from the faces on the patch. Any help is appreciated. regards Bjoern |

correction:
replace the word correction:
replace the word boundaryPatch with boundaryMesh. Still mixing it up sometimes. Reading source for several hours makes your head spin. |
