- The movie.byu geometry file format looks like this:
-
- write(iunit,80) npn,njn,nptn,nedge
- write(iunit,80) ((npl(i,j),i=1,2),j=1,npn)
- write(iunit,100) ((x(i,j),i=1,3),j=1,njn)
- write(iunit,80) (jp(i),i=1,nedge)
- 80 format(10i8)
- 100 format(6e12.5)
-
-
- where npn = number of parts (geometric objects)
- njn = number of nodes (total number of vertices)
- nptn = number of polygons (total over all parts)
- nedge = number of edges (total over all polygons in all parts)
- npl = array of pairs of indices into connectivity array for
- start polygon node and end polygon node for each part
- (if there is 1 part then it is a single line = 1 and nedge)
- x = array of 3D vertices
- jp = connectivity array - indices of vertices in x array
- making up a polygon with a negative index indicating the last
- vertex of a polygon (an n-sided polygon would have n entries in
- the connectivity array and the n-th entry would be negated).
-
- I have seen a number of programs that understand this format so its probably
- worth knowing. So does anybody know the file formats for the personal
- visualizer?
