Constructor.

Methods

virtual const mrpt::rtti::TRuntimeClassId* GetRuntimeClass() const

Returns information about the class of an object in runtime.

virtual mrpt::rtti::CObject* clone() const

Returns a deep copy (clone) of the object, indepently of its class.

void setLineCoords(float x0, float y0, float z0, float x1, float y1, float z1)

Deprecated (MRPT 2.3.1)

void getLineCoords(
    float& x0,
    float& y0,
    float& z0,
    float& x1,
    float& y1,
    float& z1
    ) const

Deprecated (MRPT 2.3.1)

virtual void updateBuffers() const

Called by the rendering system to update internal geometry buffers.

Derived classes should override this to populate their data buffers (triangles, points, lines) when the object geometry changes.

This is called automatically when hasToUpdateBuffers() returns true, which happens after notifyChange() was called.

The base implementation does nothing; derived classes should override.

Thread safety: implementations should lock the appropriate mutexes when writing to shared buffers.

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.
