List of usage examples for org.lwjgl.opengl GL11 glOrtho
public static native void glOrtho(@NativeType("GLdouble") double l, @NativeType("GLdouble") double r, @NativeType("GLdouble") double b, @NativeType("GLdouble") double t, @NativeType("GLdouble") double n, @NativeType("GLdouble") double f);
(lb – n)T and (rt – n)T specify the points on the near clipping plane that are mapped to the lower left and upper right corners of the window, respectively (assuming that the eye is located at (0 0 0)T). From source file:org.free.jake2.render.lwjgl.Main.java
