Class GLModel

java.lang.Object
  codeanticode.glgraphics.GLModel

All Implemented Interfaces:

GLConstants, processing.core.PConstants

public class GLModel
extends java.lang.Object
implements processing.core.PConstants, GLConstants

This class holds a 3D model composed of vertices, normals, colors (per vertex) and texture coordinates (also per vertex). All this data is stored in Vertex Buffer Objects (VBO) for fast access. This is class is still undergoing development, the API will probably change quickly in the following months as features are tested and refined. In particular, with the settings of the VBOs in this first implementation (GL.GL_DYNAMIC_DRAW_ARB) it is assumed that the coordinates will change often during the lifetime of the model. For static models a different VBO setting (GL.GL_STATIC_DRAW_ARB) should be used.
