Examples of javax.media.opengl.glu.GLU

javax.media.opengl.glu.GLU
Provides access to the OpenGL Utility Library (GLU). This library provides standard methods for setting up view volumes, building mipmaps and performing other common operations. The GLU NURBS routines are not currently exposed.
Notes from the Reference Implementation for this class: Thanks to the contributions of many individuals, this class is a pure Java port of SGI's original C sources. All of the projection, mipmap, scaling, and tessellation routines that are exposed are compatible with the GLU 1.3 specification. The GLU NURBS routines are not currently exposed.

    VectorXYZ pos = camera.getPos();
    VectorXYZ lookAt = camera.getLookAt();
    VectorXYZ up = camera.getUp();
    new GLU().gluLookAt(
        pos.x, pos.y, -pos.z,
        lookAt.x, lookAt.y, -lookAt.z,
        up.x, up.y, -up.z);
