The unit ROT3D displays three-dimensional data which can be rotated on-screen. The rotation of the data can be achieved either by mouse interaction or by using built-in methods of the class TRot3D. The data can be viewed from any direction, and can be zoomed and panned. Optionally, axes and/or a bounding box may be displayed. More details can be found in the online help pages.
The unit ROT3D is part of the SDL Component Suite.

ExRot3D is a simple application showing how to rotate three dimensional data in order
to create the impression of a 3D view. |
