Category: Applet Group: v10.00 >Status: Closed >Resolution: Fixed Priority: 5 Submitted By: Nobody/Anonymous (nobody) Assigned to: Miguel (migueljmol) Summary: Spacefill rendering bug Initial Comment: There is a bug with the spacefill rendering in the last Jmol version 10.00.43. When zoom is high, balls are crush against an imaginary pane. Thank's for looking that. Nico ---------------------------------------------------------------------- >Comment By: Miguel (migueljmol) Date: 2006-03-26 14:53 Message: Logged In: YES user_id=1050060 This problem was fixed in prerelease 10.00.49 by going to a 32 big z-buffer depth. I now see that Nico's report was very good ... but I did not recognize what was happening when he submitted. There is no true performance penalty for the orthogonal projection when 'set perspectiveDepth off;'. However, there is a perceived performance penalty because the atoms become much larger ... so it takes longer to render. The checked-in fix for 10.00.49 increases all screen coordinates to 32-bit integers. Therefore, there is some memory consumption increase. It also includes earlier clipping when rendering large spheres and for cylinders, significantly improving performance when zoomed in closely. ---------------------------------------------------------------------- Comment By: Nobody/Anonymous (nobody) Date: 2006-02-01 11:13 Message: Logged In: NO I just found this problem goes away if one sets the boolean variable "PerspectiveDepth" to be false. There is, however, a significant performance price for this. ---------------------------------------------------------------------- Comment By: Nobody/Anonymous (nobody) Date: 2006-02-01 09:59 Message: Logged In: NO This seems also a bug with Jmol v10 (official release). See this image : http://mw.concord.org/modeler/jmol_bug1.gif When zooming in, the spacefill rendering suddenly malfunctions. Even if the zooming percentage just increases a little bit. In the attached image, the right screenshot is a molecule that has only a slightly bigger zooming percentage than the left one. Increasing the MAXIMUM_ZOOM_PERCENTAGE constant in org.jmol.viewer.Viewer does not seem to improve. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=379133&aid=1358146&group_id=23629 ------------------------------------------------------- This SF.Net email is sponsored by xPML, a groundbreaking scripting language that extends applications into web and mobile media.
