      Method Detail
    

  


  
setUseDirectGL

  
public void setUseDirectGL(boolean drawPureGL)

  

    
Description copied from class: AbstractShape

    

      If set to true - which is the default if using the OpenGL render mode - this shape will bypass processings rendering pipeline and use the OpenGL context directly for performance increases.

      Setting this to false forces the use of the processing renderer.
      
If this is set to true, and additionally, setUseVBOs() is set to true, the shape is drawn by using vertex buffer objects (VBO).

      By calling setUseDisplayList(true) it is drawn using display lists.

      

    

    

      

        
Overrides:

        

setUseDirectGL in class MTPolygon


      

    

    

      

        
Parameters:

        

drawPureGL - the draw pure gl

      

    

  

  

  
  
setTexture

  
public void setTexture(processing.core.PImage newTexImage)

  

    
Description copied from class: AbstractShape

    

      Sets a texture for this shape.

      Uses the texture coordinates in the provided vertices for drawing.

      If openGL mode is used, it also creates a GLTexture object.

      For best compatibility, power of two texture dimensions should be provided. If the provided texture is non power of two and you are in opengl mode, we try to use the RECTANGULAR texture extension.

      If textures were disabled for this component, they are being enabled again.
      

    

    

      

        
Overrides:

        

setTexture in class AbstractShape


      

    

    

      

        
Parameters:

setAnchor

  
public void setAnchor(MTRectangle.PositionAnchor anchor)

getCenterOfMass2DLocal

  
public Vector3D getCenterOfMass2DLocal()

  

    
Description copied from class: MTPolygon

    

      Calculates the center of mass of the polygon. NOTE: works only if the last vertex is equal to the first (polygon is closed correctly) NOTE: polygon needs to be coplanar and in the X,Y plane!
      

    

    

      

        
Overrides:

        

getCenterOfMass2DLocal in class MTPolygon


      

    

    

      

        
Returns:

        
the center or mass as a Vector3D

      

    

  

  

  
  
getCenterPointLocal

  
public Vector3D getCenterPointLocal()

  

    
Description copied from class: AbstractShape

    

      Gets the center point in local object space. This should always return a COPY of the centerpoint of the implementing shape since the point may get transformed afterwards.
      

    

    

      

        
Overrides:

        

getCenterPointLocal in class MTPolygon


      

    

    

      

        
Returns:

        
the center point of this shape in untransformed local object coordinates.

      

    

  

  

  
  
setSizeLocal

  
public void setSizeLocal(float width,
                         float height)

  

    

      Sets the size locally, meaning that not the transformation of the rectangle is changed, (as setSize/setWidth, scale etc. would do) but the vertices of the rectangle themselves. This is useful if we dont want the rectangles children to be scaled as well, for example.

      Note: The scaling is done from the rectangles upper left corner - not the center!
      

    

    

      

        
Parameters:

        

width - the width

        

height - the height

      

    

  

  

  
  
setHeightLocal

  
public void setHeightLocal(float height)

  

    

      Sets the height locally, meaning that not the transformation of the rectangle is changed, (as setSize/setWidth, scale etc. would do) but the vertices of the rectangle themselves. This is useful if we dont want the rectangles children to be scaled as well, for example.

      Note: The scaling is done from the rectangles upper left corner - not the center!
      

    

    

      

        
Parameters:

        

height - the new height local

      

    

  

  

  
  
setWidthLocal

  
public void setWidthLocal(float width)

  

    

      Sets the width locally, meaning that not the transformation of the rectangle is changed, (as setSize/setWidth, scale etc. would do) but the vertices of the rectangle themselves. This is useful if we dont want the rectangles children to be scaled as well, for example.

      Note: The scaling is done from the rectangles upper left corner - not the center!
      

    

    

      

        
Parameters:

        

width - the new width local
