public class Teapot
extends Geometry

A simple teapot that is a low-level geometry primitive.

Internally this uses the OpenGL evaluators to work through the bezier patch data for rendering. The code is liberally stolen from the GLUT source which is copyright SGI. Converted to the JOGL API methods and different calling conventions.

Constructor Detail

Teapot

public Teapot(float scale,
              int gridSize)
Construct a default instance of the teapot with the given scale factor.

Parameters:
scale - The scale of the teapot to use
Method Detail

render

public void render(net.java.games.jogl.GL gl,
                   net.java.games.jogl.GLU glu)
Issue ogl commands needed for this renderable object.

Parameters:
gl - The gl context to draw with
glu - The utility context to draw with

postRender

public void postRender(net.java.games.jogl.GL gl,
                       net.java.games.jogl.GLU glu)
Restore all openGL state.

Parameters:
gl - The gl context to draw with
glu - The utility context to draw with

updateBounds

protected void updateBounds()
Update this node's bounds and then call the parent to update it's bounds. Used to propogate bounds changes from the leaves of the tree to the root. A node implementation may decide when and where to tell the parent(s)s that updates are ready.

Overrides:
updateBounds in class Geometry

recomputeBounds

protected void recomputeBounds()
Internal method to recalculate the implicit bounds of this Node. By default the bounds are a point sphere, so derived classes should override this method with something better.

Specified by:
recomputeBounds in class Geometry

markBoundsDirty

protected void markBoundsDirty()
Mark this node as having dirty bounds due to it's geometry having changed.

Overrides:
markBoundsDirty in class Geometry
