Hi Gabor,
What I am wondering is if i can know which is the number of a vert that is for example on the fron of a shape.
For example I wrote this code and it shows where is located the verts 12, 13, 14, 15, but in order to discover which was the number of these four verts located at the front face of this cube I had to try with many verts of the cube. So I was thinking if maybe there's another way to know were is each vert and the number of it, specially for more complex shapes?
(clear)
(hint-wire)
(hint-points)
(point-width 10)
(backfacecull 0)
(hint-origin)
(define cubo (build-cube))
(with-primitive cubo
(scale 4)
(display "original vert position") (newline)
(display (pdata-ref "p" 12)) (newline)
(display (pdata-ref "p" 13)) (newline)
(display (pdata-ref "p" 14)) (newline)
(display (pdata-ref "p" 15)) (newline)
(pdata-set "p" 12 (vadd (pdata-ref "p" 12) (vector -1 0 0)))
(pdata-set "p" 13 (vadd (pdata-ref "p" 13) (vector -1 0 0)))
(pdata-set "p" 14 (vadd (pdata-ref "p" 14) (vector -1 0 0)))
(pdata-set "p" 15 (vadd (pdata-ref "p" 15) (vector -1 0 0)))
(display "new position") (newline)
(display (pdata-ref "p" 12)) (newline)
(display (pdata-ref "p" 13)) (newline)
(display (pdata-ref "p" 14)) (newline)
(display (pdata-ref "p" 15)) (newline))
Thanks a lot,
Luis
