I have a polyhedral object that looks like a piece from the game "Soma". When I display it in Geomview and rotate it around, at certain orientations, the "back" of the object shows through. In other words, there seems to be some problem with hidden surface removal. A file describing the object is below. Thanks, Steve Vavasis OFF 84 12 1 0.000000 0.000000 0.000000 0.000000 2.000000 0.000000 0.000000 2.000000 1.000000 0.000000 1.000000 1.000000 0.000000 1.000000 2.000000 0.000000 0.000000 2.000000 0.000000 0.000000 0.000000 0.000000 1.000000 2.000000 0.000000 0.000000 2.000000 1.000000 0.000000 2.000000 1.000000 1.000000 2.000000 0.000000 1.000000 2.000000 0.000000 1.000000 2.000000 0.000000 1.000000 2.000000 0.000000 1.000000 1.000000 1.000000 1.000000 1.000000 1.000000 1.000000 2.000000 0.000000 1.000000 2.000000 0.000000 1.000000 1.000000 0.000000 1.000000 1.000000 0.000000 1.000000 1.000000 0.000000 1.000000 1.000000 1.000000 1.000000 1.000000 1.000000 2.000000 1.000000 0.000000 2.000000 1.000000 0.000000 1.000000 1.000000 0.000000 1.000000 1.000000 0.000000 1.000000 1.000000 0.000000 2.000000 0.000000 1.000000 2.000000 0.000000 1.000000 2.000000 1.000000 0.000000 2.000000 1.000000 0.000000 2.000000 0.000000 0.000000 2.000000 0.000000 0.000000 2.000000 0.000000 1.000000 2.000000 0.000000 1.000000 2.000000 1.000000 1.000000 1.000000 1.000000 1.000000 1.000000 0.000000 1.000000 2.000000 0.000000 1.000000 2.000000 0.000000 1.000000 2.000000 0.000000 1.000000 1.000000 0.000000 1.000000 1.000000 1.000000 2.000000 1.000000 1.000000 2.000000 1.000000 0.000000 1.000000 1.000000 0.000000 1.000000 1.000000 0.000000 1.000000 1.000000 0.000000 2.000000 0.000000 1.000000 1.000000 0.000000 1.000000 1.000000 1.000000 1.000000 2.000000 1.000000 1.000000 2.000000 0.000000 1.000000 2.000000 0.000000 1.000000 2.000000 0.000000 1.000000 2.000000 1.000000 0.000000 2.000000 0.000000 0.000000 2.000000 0.000000 1.000000 2.000000 1.000000 1.000000 2.000000 1.000000 0.000000 2.000000 1.000000 0.000000 2.000000 1.000000 0.000000 1.000000 1.000000 2.000000 1.000000 0.000000 2.000000 1.000000 0.000000 1.000000 1.000000 1.000000 1.000000 1.000000 1.000000 2.000000 1.000000 1.000000 2.000000 1.000000 1.000000 2.000000 0.000000 2.000000 0.000000 1.000000 2.000000 0.000000 1.000000 1.000000 0.000000 2.000000 1.000000 0.000000 2.000000 0.000000 0.000000 0.000000 0.000000 0.000000 0.000000 2.000000 0.000000 2.000000 0.000000 0.000000 0.000000 0.000000 0.000000 0.000000 0.000000 2.000000 1.000000 0.000000 2.000000 1.000000 0.000000 1.000000 2.000000 0.000000 1.000000 2.000000 0.000000 0.000000 7 0 1 2 3 4 5 6 0.000000 1.000000 1.000000 7 7 8 9 10 11 12 13 0.333333 0.666667 1.000000 7 14 15 16 17 18 19 20 0.666667 0.333333 1.000000 7 21 22 23 24 25 26 27 1.000000 0.000000 1.000000 7 28 29 30 31 32 33 34 0.000000 1.000000 1.000000 7 35 36 37 38 39 40 41 0.333333 0.666667 1.000000 7 42 43 44 45 46 47 48 0.666667 0.333333 1.000000 7 49 50 51 52 53 54 55 1.000000 0.000000 1.000000 7 56 57 58 59 60 61 62 0.000000 1.000000 1.000000 7 63 64 65 66 67 68 69 0.333333 0.666667 1.000000 7 70 71 72 73 74 75 76 0.666667 0.333333 1.000000 7 77 78 79 80 81 82 83 1.000000 0.000000 1.000000 Follow-Ups: problem with hidden surface removal From: mbp Prev by Date: Re: BUG report: weboogl unclean exit Next by Date: problem with hidden surface removal Prev by thread: Re: BUG report: weboogl unclean exit Next by thread: problem with hidden surface removal Index(es): Date Thread
