VIEW_3D

This widget creates a 3D view that displays a 3D Scene where 3D Objects can be aggregated and represented as a tree structure. The viewpoint for the 3D scene is set by a translation vector (tx,ty,tz) followed by a rotation defined by Euler angles (rx,ry,rz) which coordinates can be initialized and controlled by exposed parameters.

Inside VIEW_3D you can have one or more GL_OBJECT_3D, GRID_3D, COLOR_SURFACE_3D.
