Hi, I'm currently developing a software using Open CASCADE. the softwae generates points radomaly using a radom generater in VC++, these points are handled by Open CASCADE using the transformation function to display a vertx relative to a defaul co-ordinates. the only thing I need to understand is gp_dir(?,?,?) exp. what is gp_dir(0,0,1), or can someone provide me with a list of each possiblity?
Can anyone help me with this please?
