class mrpt::opengl::CRenderizable

The base class of 3D objects that can be directly rendered through OpenGL.

In this class there are a set of common properties to all 3D objects, mainly:

Its SE(3) pose (x,y,z,yaw,pitch,roll), relative to the parent object, or the global frame of reference for root objects (inserted into a mrpt::opengl::COpenGLScene).
A name: A name that can be optionally asigned to objects for easing its reference.
A RGBA color: This field will be used in simple elements (points, lines, text,…) but is ignored in more complex objects that carry their own color information (triangle sets,…)

Default constructor:

Methods

virtual void render(const RenderContext& rc) const = 0

Implements the rendering of 3D objects in each class derived from CRenderizable.

This can be called more than once (one per required shader program) if the object registered several shaders.
