Additional topics

In this chapter we mainly considered representing and drawing 3D objects using openFrameworks. For further learning, we suggest studying the following topics:

• Working with the ofLight class to control lights, that is, the type of light (spot light and point light), its position, light direction, and color parameters. See openFrameworks examples examples/3d/normalsExample and examples/3d/advanced3dExample.

• Working with the ofCamera and ofEasyCam classes to control the camera, that is, the position of the observer of the 3D scene. The camera lets you move easily through the virtual 3D world and also change perspective parameters. See openFrameworks examples examples/3d/cameraRibbonExample and examples/3d/easyCamExample.

• Using 3D model files with the .3ds and .dae extensions. You can load and draw such files as static or animated objects. Note that you can use 3D file models as a source of vertex data for further manipulation and processing. See openFrameworks examples examples...
