Constructor Details

Cube

public Cube(Panel3D panel3D,
 float xc,
 float yc,
 float zc,
 float length,
 Color color)

Create an unframed cube.

Parameters:

panel3D - the owner 3D panel

xc - x coordinate of the center

yc - y coordinate of the center

zc - z coordinate of the center

length - side length

color - fill color

Cube

public Cube(Panel3D panel3D,
 float xc,
 float yc,
 float zc,
 float length,
 Color color,
 boolean frame)

Create a cube, optionally framed.

Parameters:

panel3D - the owner 3D panel

xc - x coordinate of the center

yc - y coordinate of the center

zc - z coordinate of the center

length - side length

color - fill color

frame - if true, also draw a wireframe outline

Method Details

setLighted

public void setLighted(boolean lighted)

Enable or disable Phong-style lighting for this cube.

When enabled, each of the six faces is drawn with its own face normal via Support3D.drawShadedRectangularSolid(com.jogamp.opengl.GLAutoDrawable, float, float, float, float, float, float, java.awt.Color, java.awt.Color, float, boolean, boolean), so shading visibly changes as the cube (or the scene around it) rotates. Disabled by default, matching the flat-colour appearance existing callers already expect.

Parameters:

lighted - true to enable lighting; false for flat colour

isLighted

public boolean isLighted()

Whether Phong-style lighting is enabled for this cube.

Returns:

true if lighting is enabled

draw

public void draw(com.jogamp.opengl.GLAutoDrawable drawable)

Description copied from class: Item3D

The custom drawing method

Specified by:

draw in class Item3D

Parameters:

drawable - the OpenGL drawable

getSortPoint

public float[] getSortPoint()

Description copied from class: Item3D

A representative point for transparent sorting, in world coordinates. Default is origin. Override in items with a natural center (Sphere, Cube, Cylinder, etc.).

Overrides:

getSortPoint in class Item3D

Returns:

the sort point as [x, y, z]
