I am a newcomer to the world of gaaphics. We are trying to simulate
a manipulator on Sun 3 workstation using SunCore 3-D graphics library.
For this purpose, we want to create several solid objects and transform
each of them independently in 3-D.
I am trying to get some SAMPLE PROGRAM that can create atleast
one solid object (cylinder, filled polygon, box etc) and perform
simple transformations about all 3-axis.
Also I have a few questions for people who might be familiar with
SunCore.
1) Can I change the projection of object, i.e. angle of x, y and z axis
with respect to the screen from the default orientation of
y

|----------> x and z-axis going straight into the screen.
2) Is there any easier way (other than giving 3-D coordinates for the
whole object) to create a solid symmetrical objects?
(like creating a 2-D segment with all coordinates and then applying
translation or rotation of this newly created segment to produce
a 3-D object before closing the segment for displaying on the screen?)
3) how to prevent transformation on one segment (object) from erasing
other segment (object) from the screen. I can redisplay every objects
for movement in any single object but that will be very slow.
Any pointers and source code(in C or FORTRAN) would be most appreciated!
Thanks a lot.
