Default X Y Z

Is there any way to find the dimensions of a generated object useing AC3D in terms of X,Y,Z (using DX's scale)? I find it hard to find these numbers. I have been trying to make a game, but I have to render the image in my DX engine, and move around it to get its size.

Within AC3D, select the object and read the size from the info. at the top of the control panel.

You can also use this to get distances - select any two vertices and it will show you the distrnce between them.

Sorry to bring up such an old post; however, I would like to know if there is a way to get the ACObject's dimensions through the SDK. If so, how do you do this?

Thanks

Try:

Code:
Prototype int ac_object_find_bound(ACObject *ob, Point3 *max, Point3 *min); // returns 0 if no geometry (therefore bb is invalid)
then something like this:

Code:
 
Prototype void find_box_size(Point3 *max, Point3 *min, Point3 *out)
{
Point3 diff = *max;
 
SUBTRACTPOINTS(min, &diff);
ABSPOINT(&diff);
*out = diff;
}
