mrpt::opengl::CCamera Class Reference

---

Detailed Description

A camera: if added to a scene, the viewpoint defined by this camera will be used instead of the camera parameters set in COpenGLViewport::m_camera.

A camera can be defined to provide a projective or orthogonal view of the world by setting the member CCamera::m_projectiveModel.
