From SOFAWiki

For each point defined in an .obj file, this engine computes a set of rigid points using the normals. Normal vector will be collinear to the Z axis and orthonormal to X and Y as showed bellow:

Y
|       
|   / X
|  /
| /
|/_ _ _ _ _ Z/normal

Input Data's

• normals

normals defined in the .obj file.

• vertices

vertices defined in the .obj file.

Output Data's

• frames

Set of rigid types oriented as described before.

Examples

Examples using this engine can be found in :

examples/Components/engine/vertex2Frame.scn

where the engine is used as follow:

	<MeshLoader name="meshLoader"  filename="mesh/icosahedron.obj"/>
	<Vertex2Frame name="vertex2frame" template="Rigid" vertices="@meshLoader.vertices" texCoords="@meshLoader.texCoords" normals="@meshLoader.normals" facets="@meshLoader.facets"/>
	<MechanicalObject name="dofs" template="Rigid" position="@../vertex2frame.frames" />
