MTTriangleMesh

  
public MTTriangleMesh(processing.core.PApplet pApplet,
                      GeometryInfo geometryInfo)

  

    

      Creates a new triangle mesh.
      
Important: This mesh expects triangles geometry!

      Method Detail
    

  


  
setGeometryInfo

  
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!
      

    

    

      

        
Overrides:

        

setGeometryInfo in class AbstractShape


      

    

    

      

        
Parameters:

        

geometryInfo - the geometry info

      

    

  

  

  
  
setVertices

  
public void setVertices(Vertex[] vertices)

  

    
Description copied from class: AbstractShape

    

      Sets new vertices for that shape. and generates new vertex arrays for opengl mode.
