Examples with BooleanHolder maspack.util.BooleanHolder used on opensource projects

Example 1 with BooleanHolder

use of maspack.util.BooleanHolder in project artisynth_core by artisynth.

the class SurfaceMeshIntersector method createContourVertices.

/**
 * Creates mesh vertices corresponding to each contour intersection point in
 * a ContactInfo structure. These vertices can then be used in the formation
 * of a CSG mesh associated with the intersection. The vertex associated
 * with each intersection point is stored in the point's
 * <code>myVertex</code> field. A single common vertex is created for points
 * which are very close together. Also, for points which are very close to
 * an original vertex on one of the intersecting meshes, the newly created
 * vertex is projected onto the original vertex and an association from the
 * original to the new vertex is recorded in a vertex-vertex
 * <code>HashMap</code> which is returned by this method. Other new vertices
 * which are not associated with original vertices are stored in the
 * argument <code>contourVtxs</code>.
