[comp.graphics] 2 Questions

jclst1@unix.cis.pitt.edu (Joseph C. Lappa) (11/18/90)

I need help with 2 questions that I have:

	1) is there a resonable way to enter 3D points into a window
	(Xwindows)  using only a mouse.  

	2) Right now we're using a product called DI3000 by Precision
	Visuals to do graphics on our VMS mainframes and Cray.  DI3000
	is a collect of subroutines that are linked at run time which can plot
	and manipulate 2d and 3d info.  Does anyone know of any products which 
	has the same capablites, but with a lower price.


						Thanks

I saw an article back in 1987 about a scheme where you use your standard three
views from drafting.  You anchor two of the three dimensions in one view 
(window), and then move two one of the other two views (windows) to get the
other dimension.  I had been thinking about a scheme like this myself for a CAD
package I wanted to write before ever seeing the article, but they published
it first.  Alas, I do not remember WHICH graphics journal I saw it in.
