Method Detail

computeInverseVertexMasses

static float[] computeInverseVertexMasses(de.javagl.simplemesh.MeshPrimitives meshPrimitives,
                                          float massPerSquareMeter)

Compute the inverse masses of the vertices of the given MeshPrimitives.

Parameters:

meshPrimitives - The mesh primitives

massPerSquareMeter - The desired mass per square meter

Returns:

The inverse vertex masses

computeBendingEdges

public static java.util.List<de.javagl.simplemesh.Edge> computeBendingEdges(de.javagl.simplemesh.MeshPrimitives meshPrimitives)

Compute all bending edges for the given mesh primitives. That is, for all pairs of triangles that have a common edge, this method creates an edge between the vertices of the triangles that are not part of the common edges. It is made sure that no double edges are contained in the resulting list.

Parameters:

meshPrimitives - The mesh primitives

Returns:

The list of bending edges

computeEdgeRestLengths

static float[] computeEdgeRestLengths(java.util.Collection<? extends de.javagl.simplemesh.Edge> edges)

Compute the rest lengths for the given edges. This method assumes that the vertices of the given edges are in their rest state, and the array will simply contain the current lengths of the given edges.

Parameters:

edges - The edges

Returns:

The rest lengths
