I am new to this news group and to the graphics world in general, so
let me apologize in advance if I ask something stupid or use graphics
terminology incorrectly.
I have to write a program that will:
(1) Accept a wireframe representation of a solid object as input.
(2) Next, the program will determine the solid object from its wireframe.
(3) Finally, it will output a certain number of slices of that object.
What I mean by wireframe is that the solid is broken into a
representation of lines, points, arcs/circles, and splines. But, there are
no relationships given between these different parts (i.e. no surface
representations.) You could probably determine surfaces by transversing
all the given data. For example, if the starting vertex of a line is
the same as the ending vertex of a different line, then the two lines
must form a point. By the way, all the data is given in three-dimensions.
I feel that (1) and (3) will be trivial. The part I'm having
problems with is (2).
My biggest question is:
Is it possible to determine a solid if your only given its wireframe
representation?
If you have any comments or suggestions or know of references that
may be helpful please let me know.
