[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [ REQ 5386]: Bounding Box and Geomview ... here is the workaround
Dear Sirs, I have reported that Geomview and its derivatives (cyberview-x,cyberview3d), generate a huge bounding box oversized, for an object having coords 21 < X < 38 17 < Y < 35 1 < Z < 8 The effect can be observed by loading http://www.embl-heidelberg.de/ExternalInfo/CG/Cyberview-x/start.html and load the chromosome.off I have then observed the examples provided and found that the object ikarab.oogl that is correctly displayed, has the following minmax ranges 0 < x < 10 0 < y < 10 0 < z < 10 I just tried that out on my data, and the result can be observed if you load smallchromosome.off Perhaps you could make a note in your documentation and put a warning on the WWW page about this workaround. There still a problem that is bugging me a bit, that is the number of triangles that is specified in the header must be equal to the number of vertices/3. That makes no sense, is not shown anywhere in the doc, and is not shown in the examples as well. Therefore I am investigating on it ... The object shown in the smallchromosome.off is made from AVS using a WRITE_OOGL module that I have written. As soon as I will have it "stable" than I will put it on the WWW and let you know. The object has 52815 points and 29368 triangles with shared vertices. What I do not understand is why I must put in the header of the OFF file the magic number 17605 (that is #/3) ... nowhere is described in the docs that triangles cannot share vertices ... ?!? best regards Luca Ida Giovanni TOLDO (Ph.D) European Molecular Biology Laboratory Computer Group Heidelberg Germany
