class CMesh3D : public virtual mrpt::viz::CVisualObject, public mrpt::viz::VisualObjectParams_Lines, public mrpt::viz::VisualObjectParams_Triangles
A 3D mesh composed of triangles and/or quads. A typical usage example would be a 3D model of an object.

void loadMesh(unsigned int num_verts, unsigned int num_faces, int *verts_per_face, int *face_verts, float *vert_coords)
Load a 3D mesh. The arguments indicate:
num_verts: Number of vertices of the mesh
num_faces: Number of faces of the mesh
verts_per_face: An array (pointer) with the number of vertices of each face. The elements must be set either to 3 (triangle) or 4 (quad).
face_verts: An array (pointer) with the vertices of each face. The vertices of each face must be consecutive in this array.
vert_coords: An array (pointer) with the coordinates of each vertex. The xyz coordinates of each vertex must be consecutive in this array.

void loadMesh(unsigned int num_verts, unsigned int num_faces, const mrpt::math::CMatrixDynamic<bool> &is_quad, const mrpt::math::CMatrixDynamic<int> &face_verts, const mrpt::math::CMatrixDynamic<float> &vert_coords)
Load a 3D mesh. The arguments indicate:
num_verts: Number of vertices of the mesh
num_faces: Number of faces of the mesh
is_quad: A binary array saying whether the face is a quad (1) or a triangle (0)
face_verts: An array with the vertices of each face. For every column (face), each row contains the num of a vertex. The fourth does not need to be filled if the face is a triangle.
vert_coords: An array with the coordinates of each vertex. For every column (vertex), each row contains the xyz coordinates of the vertex.

-
virtual void updateBuffers() const override
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.
Note
Thread safety: implementations should lock the appropriate mutexes when writing to shared buffers.
-
virtual mrpt::math::TBoundingBoxf internalBoundingBoxLocal() const override
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.
