bitangent void bitangent(Vector3d v1, Vector2d uv1, Vector3d v2, Vector2d uv2, Vector3d v3, Vector2d uv3, Vector3d dest): Calculate the surface bitangent for the three supplied vertices and UV coordinates and store the result in <code>dest</code>.
normal void normal(Vector3d v0, Vector3d v1, Vector3d v2, Vector3d dest): Calculate the normal of a surface defined by points <code>v1</code>, <code>v2</code> and <code>v3</code> and store it in <code>dest</code>.
normal void normal(float v0X, float v0Y, float v0Z, float v1X, float v1Y, float v1Z, float v2X, float v2Y, float v2Z, Vector3d dest): Calculate the normal of a surface defined by points <code>(v1X, v1Y, v1Z)</code>, <code>(v2X, v2Y, v2Z)</code> and <code>(v3X, v3Y, v3Z)</code> and store it in <code>dest</code>.
perpendicular void perpendicular(float x, float y, float z, Vector3d dest1, Vector3d dest2): Compute two arbitrary vectors perpendicular to the given normalized vector <code>(x, y, z)</code>, and store them in <code>dest1</code> and <code>dest2</code>, respectively. <p> The computed vectors will themselves be perpendicular to each another and normalized. So the tree vectors <code>(x, y, z)</code>, <code>dest1</code> and <code>dest2</code> form an orthonormal basis.
perpendicular void perpendicular(Vector3d v, Vector3d dest1, Vector3d dest2): Compute two arbitrary vectors perpendicular to the given normalized vector <code>v</code>, and store them in <code>dest1</code> and <code>dest2</code>, respectively. <p> The computed vectors will themselves be perpendicular to each another and normalized. So the tree vectors <code>v</code>, <code>dest1</code> and <code>dest2</code> form an orthonormal basis.
tangent void tangent(Vector3d v1, Vector2d uv1, Vector3d v2, Vector2d uv2, Vector3d v3, Vector2d uv3, Vector3d dest): Calculate the surface tangent for the three supplied vertices and UV coordinates and store the result in <code>dest</code>.
tangentBitangent void tangentBitangent(Vector3d v1, Vector2d uv1, Vector3d v2, Vector2d uv2, Vector3d v3, Vector2d uv3, Vector3d destTangent, Vector3d destBitangent): Calculate the surface tangent and bitangent for the three supplied vertices and UV coordinates and store the result in <code>dest</code>.
