Recently I found this great tutorial on spherical environment mapping which is an easy solution to add some detailed lighting to a visualisation. The great thing about this technique, is that you can use a simple 2D texture to define how the lighting and reflection of you model looks.

Web23 de ago. de 2024 · Unlike IRIS GL, OpenGL has separate functions for setting lights, light models and materials. Keep the following points in mind when porting lighting and materials functions: OpenGL has no table of stored definitions. You can use display lists to mimic the IRIS GL def/bind mechanism.

In OpenGL, to enable or disable lighting, users need to call glEnable (GL_LIGHTING) or glDisable (GL_LIGHTING). When lighting is enabled, colors that are specified by glColor * () will become invalid. Light position is set using GL_POSITION.
