But in terms of coloring your .obj models before hand:
If you have a .mtl (materials) file associated with the .obj (the start of the mymodel.obj file should read like # mtllib mymodel.mtl ) the model will be coloured accordingly. The .mtl file contains descriptions of materials applied to geometry groups in the .obj file e.g. .mtl color newmtl aqua Ka 0 0.2653 0.2653 Kd 0 0.5 0.5 Ks 0 0.6163 0.6163 Tf 0 0 0 Ns 60 Ni 1 illum 2 sharpness 0 d 1 can be applied to a part of mymodel.obj g myaquagroupname usemtl aqua s 1 f 8096 8095 8064 8061 f 8095 691 8072 8064 f 691 8093 8074 8072 f 8093 8094 8076 8074 f 8094 750 8084 8076 ... =========================================================================== To unsubscribe, send email to [EMAIL PROTECTED] and include in the body of the message "signoff JAVA3D-INTEREST".
