HI I am sorry. There was a mistake in my mail of the point. > The color change of 2500 Attributes takes about six seconds. -> Not 2500 changes, 10000 changes properly. Then, I was forgotten to specify my executive environment. My executive environment is WindowsNT4.0(SP4)+jdk1.3+j3d1.2.2 OpenGL. And, Mr.Ito gave me reply. With his executive environment.... In case of 10000 Shape3D attribute change --- about 3 sec. In case of 2500 Shape3D attribute change --- about 0.3 sec. Incidentally, his executive environment is Athlon 800MHz, 512MByte, GeForce256DDR jdk1.3, Java3D 1.2 OpenGL WindowsNT 4.0 SP6 Is this measuring value reasonable?
