Construction

CSphere(float radius = 1.0f, int nDivsLongitude = 20, int nDivsLatitude = 20)

Constructor.

Methods

virtual void renderUpdateBuffers() const

Called whenever m_outdatedBuffers is true: used to re-generate OpenGL vertex buffers, etc.

before they are sent for rendering in render()

virtual bool traceRay(const mrpt::poses::CPose3D& o, double& dist) const

Simulation of ray-trace, given a pose.

Returns true if the ray effectively collisions with the object (returning the distance to the origin of the ray in “dist”), or false in other case. “dist” variable yields undefined behaviour when false is returned

virtual mrpt::math::TBoundingBox getBoundingBox() const

Evaluates the bounding box of this object (including possible children) in the coordinate frame of the object parent.
