public class TSphere3D

extends TEntity3D

This object is inherited from TEntity3D. It contains a 3D model for a sphere. At the moment the projection is just a flat circle with the radius and position projected correctly. TODO: make the sphere phong shaded

Method Detail

Sphere3D

public TSphere3D Sphere3D(double _x,
                          double _y,
                          double _z,
                          double _R)

A constructor like routine. Changes the variables of the sphere.

Draw

public void Draw(TCamera3D _cam,
                 Viewport _viewport)

Description copied from class: TEntity3D

Draws the vissible parts of this object onto the viewport, as if it where projecting itself on a camera.

Overrides:

Draw in class TEntity3D

Tags copied from class: TEntity3D

Parameters:

_cam - The camera.

_Viewport - Viewport object. This viewport object handles clipping and transformation of real world coordinates to screen coordinates. It does the real drawing on the screen.

TCamera3D, Viewport

Depth

public double Depth(TCamera3D _cam)

Description copied from class: TEntity3D

This routine prerenders the objects and calculates the distances from the object to the camera (depth). If more than one 3D object is inside this object, it returns the average depth. This depth can be used by a a parent TEntityList3D object to sort all TEntity3D's according to depth.

Overrides:

Depth in class TEntity3D

Tags copied from class: TEntity3D

Parameters:

_cam - The camera.
