[java] sawtooth when loading a self-made data using Java3D...

24 May 2010 - 08:53 PM

Hi, all: I'm trying to load a 3D data at http://www.visionopen.com/input_sample_sphere_radiation.dat. However, when loading, by using Java3D, I always obtain those sawtooths, please refer to file http://www.visionopen.com/input_sample_sphere_radiation.jpg If using "tecplot" (refer to http://www.tecplot.com/ ), I'm able to obtain much better result as http://www.visionopen.com/input_sample_sphere_radiation_trecplot.jpg Can anybody help to load the 3D data file "input_sample_sphere_radiation.dat" without too much sawtooths? In addition, be kind enough to leave your code as well? BTW, my code to load it is attached:
gi = new GeometryInfo(GeometryInfo.POLYGON_ARRAY);
gi.setCoordinates(getNodesVertices1());
int[] element = getElements();
gi.setCoordinateIndices(element);
gi.setStripCounts(getStripCount1());
gi.setColors(getColor1());
gi.setColorIndices(element); 
Looking forward to your reply. Best Regards JIA Pei

Hi, gamedev: How to check "some user's topics"? Say, if I just want to check all the topics that the user "abc" has participated in, better to separate those topics started by "abc" and those topics that "abc" followed up??? Best Regards JIA

[java] java3d in Ubuntu 9.10 can't update screen promptly...

27 April 2010 - 06:49 AM

Hi, all:

Urgently need your help.

I met this problem long time ago and till now, I couldn't have managed to solve it. Unlike in Ubuntu 8.10, Java3D seems to be incompatible with my current Video driver in Ubuntu 9.10.

I uploaded a video at
http://www.visionopen.com/java3d_ubuntu910.ogv

As shown, Java3D is not able to erase the old leftovers whenever I move the canvas to a different place.


Did anybody meet the same problem and is there a way out to eliminate this terrible problem of display?

Looking forward to your kind and prompt help.

Best best Regards
