Hi Mr June
I appreciate the fine work you did on 3D rotation XYZ axis , the perspective aspect adds realism to the images that can be formed.
There are a wide variety of structures that can be rendered in this format.
Please continue to "push the envelope" in this space.
I like to link relational database(MS Access) to MS Visio , using VBA coded SQL to import the image information's coordinates from the underlying database tables. Thereafter encode VBA routines to automate the drawing of shapes using your 3D formula constructs.
