Class TextureCoords

java.lang.Object

com.jogamp.opengl.util.texture.TextureCoords

public class TextureCoords
extends Object

Specifies texture coordinates for a rectangular area of a texture. Note that some textures are inherently flipped vertically from OpenGL's standard coordinate system. This class takes care of this vertical flip so that the "bottom" and "top" coordinates may sometimes be reversed. From the point of view of code rendering textured polygons, it can always map the bottom and left texture coordinates from the TextureCoords to the lower left point of the textured polygon and achieve correct results.
