Direct Known Subclasses:

public abstract class Vob

extends java.lang.Object

A two-dimensional renderable, interpolatable object. A Vob is simply an object able to render itself. Instead of just painting we create a temporary structure of Vobs (VobScene) in order to be able to paint all the data in the correct depth-order and to interpolate between views..

Vobs are just renderable things; they do not contain any information about identity. Identity is handled in VobCoorder, where each coordinate system can be given a key.

Method Detail

intersect

public boolean intersect(int x,
                         int y,
                         Vob.RenderInfo info1,
                         Vob.RenderInfo info2)

render

public abstract void render(java.awt.Graphics g,
                            boolean fast,
                            Vob.RenderInfo info1,
                            Vob.RenderInfo info2)

Renders this vob at the given screen coordinates and in given size.

Parameters:

g - The graphics context to draw into The color should already be set to the default foreground color, mixed by the caller.

fast - Whether to draw quickly (true) or beautifully (false)

info1 - General parameters and coordinate systems of cs1

info2 - General parameters and coordinate systems of cs2

addToListGL

public final int addToListGL(int[] list,
                             int curs,
                             int coordsys1,
                             int coordsys2)

putGL

public int putGL(VobScene vs)

For OpenGL: Add the current vob to the given display list, using the given coordinate systems. There are two alternatives: for composite Vobs, this will call vs.put for the components, for "real" GL Vobs, this will return the GL index.
