Construction

CDisk()

Constructor.

Methods

virtual void onUpdateBuffers_Triangles()

Must be implemented in derived classes to update the geometric entities to be drawn in “m_*_buffer” fields.

void setSlicesCount(uint32_t N)

Default=50.

virtual mrpt::math::TBoundingBoxf internalBoundingBoxLocal() const

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

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

Ray tracing.
