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? david blythe ontario centre for large scale computation drb@clsc.utoronto.ca
