From SOFAWiki

This engine extrude a surface and returns corresponding triangles.

Input Data's

• triangles

list of triangles of the object to extrude. /!\ It must me a vector of BaseMeshTopology::Triangle

• surfaceTriangles

list of triangles of the surface to extrude. /!\ The type of triangle must be BaseMeshTopology::TriangleID, and not BaseMeshTopology::Triangle

• surfaceVertices

list of positions

Output Data's

• extrusionVertices

list of positions of the new triangles, created from extrusion

• extrusionTriangles

list of triangles from extrusion (vector of BaseMeshTopology::Triangle)

Important Parameter

• heightFactor

extrusion is based on normals. So, this factor defines the final height of the extrusion.

Examples

See multi-engines example. Typically, a line in scene file will be in this form :

<ExtrudeSurface name="extrusion1"  template="Vec3d" triangles="@Topology.triangles" surfaceVertices="@MechanicalObject.rest_position" surfaceTriangles="@SurfaceIWant.indices" heightFactor="2.0"/>
