GLNODE Create a GL Node

Section: OpenGL Models


Define a GL Node. A GL Node is an object that can be displayed in a GL Window. It is defined by a triangular mesh of vertices. It must also have a material that defines its appearance (i.e. color, shininess, etc.). The syntax for the glnode command is

where material is the name of a material that has already been defined with gldefmaterial, pointset is a 3 x N matrix of points that define the geometry of the object. Note that the points are assumed to be connected in triangular facts, with the points defined counter clock-wise as seen from the outside of the facet. FreeMat will compute the normals. The name argument must be unique. If you want multiple instances of a given glnode in your GLWindow, that is fine, as instances of a glnode are created through a glassembly.
