Class NormalGenerator
java.lang.Object
com.jme.util.geom.NormalGenerator
public class NormalGenerator
- extends java.lang.Object
A utility class to generate normals for TriMeshes.
The generator generates the normals using a given crease angle up to which
the transitions between two triangles are to be smoothed. Normals will be
generated for the mesh, as long as it uses the default triangle mode (TRIANGLE
) -
the modes TRIANGLE_FAN
and TRIANGLE_STRIP
are
not supported.
The generator currently only supports a single set of texture coordinates in
a mesh. If more than one set of texture coordinates is specified in a mesh,
all sets after the first one will be deleted.
Please note: The mesh must be manifold, i.e.
only 2 triangles may be connected by one edge, and the mesh has to be
connected by means of edges, not vertices. Otherwise, the normal generation
might fail, with undefined results.

public void generateNormals(TriMesh mesh,
float creaseAngle)
- Generates the normals for one TriMesh, using the specified crease
angle.
- Parameters:
mesh
- The TriMesh to generate the normals forcreaseAngle
- The angle between two triangles up to which the normal between
the two triangles will be interpolated, creating a smooth
transition
