问题
I use Three.js ver. 65 The browsers are Firefox ver. 27.0.1 and Chrome 32.0.1700.107 m. I tested the app on Windows Xp, 7 and 8.
My problems are the following (http://jsfiddle.net/j8DN6/4/):
1) What I can not understand is why the sprites are not centered respect to the center of the Cartesian axes.
I.e:
spritey.position = (0, 0, 0);
2) The sprites unlike other objects, which rotate properly around the z axis, they follow strange trajectories different from those expected.
3) If I turn the 3d radar-chart along the x-axis the sprites, which were in front of the circles of the radar chart, changing position by moving back.
I hope I was clear. Thanks in advance.
