Constructor Detail


public MTTriangleMesh(processing.core.PApplet pApplet,
                      GeometryInfo geometryInfo)
Creates a new triangle mesh.

Important: This mesh expects triangles geometry!


public MTTriangleMesh(processing.core.PApplet pApplet,
                      GeometryInfo geometryInfo,
                      boolean calculateDefaultNormals)
Creates a new triangle mesh.

Important: This mesh expects triangles geometry!

Method Detail


public void setGeometryInfo(GeometryInfo geometryInfo)
Description copied from class: AbstractShape
Sets a new geometryInfo with new vertices for this shape.
If running in OpenGL mode, this also creates new vertex buffers for openGL use and eventually new Vertex Buffer Objects or Displaylists depending on the objects settings! So DONT create them (buffers or vbos) on the geometryinfo yourself manually, prior to setting it here!
Also calls computeDefaultBounds() if setAutoComputeBounds() is true (default) to recreate the bounding shape.
NOTE: Be aware, that an old geometryinfo of this shape may have created VBOs or displaylists on the gfx card which we should delete if not needed anywhere else!

setGeometryInfo in class AbstractShape
geometryInfo - the geometry info


public void setVertices(Vertex[] vertices)
Description copied from class: AbstractShape
Sets new vertices for that shape. and generates new vertex arrays for opengl mode.
