I have used already the 'in' command, the 'make' command is my mistake when I was writing the mail. This is the Appendix C, of course. :) > It would be great if someone(tm) would work on a consolidated > document that describes each primitive in detail or a tutorial that > documents selecting and specifying parameters to primitives. There > are lots of opportunities to contribute. ;-) I would like to work on a tutorial that documents selecting and specifying parameters to primitives. Say, for the Right Elliptical Cylinder (rec) in this future tutorial I would like to write down the following: >>*** Right Elliptical Cylinder (rec) >>A,B,V,C,D >>-Vertex, V (the center of the geometrical body) >>-Height vector, H >>-Major axis for the ellipse, A,C >>-Minor axis for the ellipse, B,D >> >>Stored as a tgc, where vectors A and C have equal lengths, B and D >>have equal lengths, and all vectors are perpendicular to H. An example follow how to create 'rec' with 'in' command: >>the button: >>mged> in btn.s rec 8 30 36 0 3 0 4 0 0 0 0 2 >> >>The meaning of these 12 number is: >>********************************** >> >>**** the (x y z) coordinates of the Vertex (8 30 36) >>**** the (x y z) coordinates of the hights end point (0, 3, 0) >>**** the (x y z) coordinates of the A vectors end point (4 0 0) >>**** the (x y z) coordinates of the B vectors end point (0 0 2) What do you mean about this schema? -- Regards, Paul Csanyi http://www.freewebs.com/csanyi-pal/index.htm ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ BRL-CAD Users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/brlcad-users
