Member Function Documentation

checkOrientation()

void checkOrientation ( )

private

check the orientation of the patches in the triangulated surface

sort all surface facets into groups consisting of facets with consistent orientation. Do not cross non-manifold edges

check the orientation of triangles at this edge check the sign of the angle if the orientation is not consistent

find the octree leaves containing each triangle

check the orientation of all facets in a group and collect their votes

find the OUTSIDE octree cubes in the vicinity of the triangle and check the orientation of the triangle

check whether the ray casted from the centre of the triangle intersects the cube

found an intersection in the positive direction

found an intersection in the negative direction

determine whether a group is oriented outward or inward

Finally, set the orientation of the normal

Here is the call graph for this function:

classifyEdgesTypes()

void classifyEdgesTypes ( )

private

classify edges based on the orientation of the surface facets

set feature edge types

Finally, check the edges and assign flags

this is not a manifold edge

surface is a manifold at this edge

facet is outward oriented

this is a convex edge

this is a concave edge

facet is inward oriented

this is a convex edge

this is a concave edge
