I want to write an AutoLISP routine to help me unfold some 3D assemblies into flat (exploded) layouts. Yes, there are software packages out there that can do this automagically for 3D solids, but I ...

I have two points with x,y, and z coordinates in 3d space. How can I derive the separate angles of the x,y, and z axes?<BR><BR>In case you're curious, I have a direct3d assignment, and I already have ...

Brush up on your knowledge of working with vectors, including how to evaluate scalar product and determine the angle between two vectors ...

The scalar product \(a.b\) is defined as \(\textbf{a.b}=\left|\textbf{a}\right|\left|\textbf{b}\right|\cos\theta \) where \(\theta\) is the angle between \(\textbf{a ...
