It defines + * a special kind of texture mapping which is composed of a set of six + * 2D images representating the six faces of a cube. The texture coordinate + * (s,t,r) is used as a 3D direction vector emanating from the center + * of a cube to select a particular face of the cube based on the + * largest magnitude coordinate (the major axis). A new 2D texture coordinate + * (s,t) is then determined by dividing the other two coordinates (the minor + * axes) by the major axis value. The new coordinate is then used for + * texel lookup from the selected texture image of this cube map. + * + * The TextureCubeMap image is defined by specifying the images for each + * face of the cube. The cube map texture can be thought of as centered at + * the orgin of and aligned to an XYZ coordinate system. The names + * of the cube faces are: + * + * <UL> + * <LI>POSITIVE_X</LI> + * <LI>NEGATIVE_X</LI> + * <LI>POSITIVE_Y</LI> + * <LI>NEGATIVE_Y</LI> + * <LI>POSITIVE_Z</LI> + * <LI>NEGATIVE_Z</LI> + * </UL> + * + * <p> + * Note that as of Java 3D 1.5, the texture width and height are no longer + * required to be an exact power of two. However, not all graphics devices + * supports non-power-of-two textures. If non-power-of-two texture mapping is + * unsupported on a particular Canvas3D, textures with a width or height that + * are not an exact power of two are ignored for that canvas. + * + * @see Canvas3D#queryProperties + * + * @since Java 3D 1.3 + */ +public class TextureCubeMap extends Texture { + + // TODO KCR : NPOT + + /** + * Specifies the face of the cube that is pierced by the positive x axis + */ + public static final int POSITIVE_X = 0; + + /** + * Specifies the face of the cube that is pierced by the negative x axis + */ + public static final int NEGATIVE_X = 1; + + /** + * Specifies the face of the cube that is pierced by the positive y axis + */ + public static final int POSITIVE_Y = 2; + + /** + * Specifies the face of the cube that is pierced by the negative y axis + */ + public static final int NEGATIVE_Y = 3; + + /** + * Specifies the face of the cube that is pierced by the positive z axis + */ + public static final int POSITIVE_Z = 4; + + /** + * Specifies the face of the cube that is pierced by the negative z axis + */ + public static final int NEGATIVE_Z = 5; + + + /** + * Constructs a texture object using default values. + * Note that the default constructor creates a texture object with + * a width of 0 and is, therefore, not useful. + */ + public TextureCubeMap() { + super(); + } + + /** + * Constructs an empty TextureCubeMap object with specified mipmapMode + * format, and width.
