    )

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 slices)

Number of radial divisions.

uint32_t getSlicesCount() const

Number of radial divisions.

virtual void getBoundingBox(mrpt::math::TPoint3D& bb_min, mrpt::math::TPoint3D& bb_max) const

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

virtual shader_list_t requiredShaders() const

Returns the ID of the OpenGL shader program required to render this class.
