class mrpt::opengl::CSetOfTexturedTriangles

A set of textured triangles.

This class can be used to draw any solid, arbitrarily complex object with textures.

Methods

virtual void onUpdateBuffers_TexturedTriangles()

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

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

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
