Dear Jean,
I am trying to feed the 3d-objects into the 3d-viewer box. It seems that the patch was constructed in a wrong way, so that I got some error message by double-clicking or evaluating the 3d-viewer.
(for example this one: ERROR: No applicable methods for #<standard-generic-function (setf vertices-colors) 41D0134524> with args ((nil nil nil nil nil nil nil nil) #<3d-cube 40300C9093>))
I wonder if there are some tutorial patches or examples of using this box?
By the way, is there an easy way to create new types of 3d-objects beside the 3d-lines, 3d-cube, 3d-sphere? I am learning the cl-opengl at the moment, it looks very related to this subject.
Thank you so much for your help!
Best regards,
Jialin
