Data Structures
class	Visual3d_ViewOrientation
	This class allows the definition of the manner in which an observer looks at the visualised scene. It defines a coordinate system called VRC (View Reference Coordinates) with 3 axes U,V,N Summary of 3D View Orientation -- -- The view orientation transformation defines -- the relationship between World Coordinates -- (WC) and View Reference Coordinates (VRC) -- -- To define a view orientation transformation -- you must define : -- -- The View Reference Point (VRP) -- The View Plane Normal (VPN) -- The View Up Vector (VUP). -- Optionally, it is possible to specify anisotropic (axial) scale factors. This allows to scale the scene using individual scale values along each coordinate axis. More...
