Interface GeometryArrayNormal

public interface GeometryArrayNormal

An interface that represents the result of tesselating a parametric surface when the tesselation also returns vectors normal to the surface

Method Summary

Modifier and Type	Method	Description
javax.vecmath.Vector3f[]	normals()	Returns normal vectors Normals are oriented consistently (assuming parametric surface is non-degenerate) Oriented so that following system of vectors in 3D Euclidean space is right handed: "x" -- the direction of the "u", first parametric coordinate "y" -- the direction of the "v", second, parametric coordinate "z" -- the normal vector normals are of unit magnitude

Method Details

normals

javax.vecmath.Vector3f[] normals()

Returns normal vectors Normals are oriented consistently (assuming parametric surface is non-degenerate) Oriented so that following system of vectors in 3D Euclidean space is right handed: "x" -- the direction of the "u", first parametric coordinate "y" -- the direction of the "v", second, parametric coordinate "z" -- the normal vector normals are of unit magnitude

Returns:

array (of length numPoints) of normal vectors
