Methods

void setSlicesCount(uint32_t slices)

Number of radial divisions

uint32_t getSlicesCount() const

Number of radial divisions

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

Must be implemented by derived classes to provide the updated bounding box in the object local frame of coordinates.

This will be called only once after each time the derived class reports to notifyChange() that the object geometry changed.

getBoundingBox(), getBoundingBoxLocal(), getBoundingBoxLocalf()

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
