Define 1. 3D objects

3D objects are objects that occurs on a three-axis Cartesian coordinate system.

Cocos2D-x is, as you might infer from its name, a 2d gaming library. But, as it usesOpenGL internally to draw its stuff, we might leverage it to create some 3D objects onthe mix.

Cocos2D-x use vector 2D but with C++ we can define vector 3D.

Define 2. Vector3D

Typedef struct {GLfloat x ;GLfloat y ;GLfloat z ;} Vector3D ;

But it has some issues like :

1 Doesn’t allow you to draw sprites on top of the boxes.

2 The gluLookAt call shouldn’t be inside the Box class draw method.

3 The color shading is hardcoded.

4 And so on, so on...

Define 2. Vector3D

Although I don’t recommend using Cocos2D-x for making a complete3D game, adding some 3D objects might bring some interestingeffects.
