Tony - 12 / 27

Probably not news to anyonelse but I here's some notes on the 'ol cube again.  I tried to draw / animate the cube tumbling in the air in perspective but failed pretty miserably.  Thus prompting me to go back and study the cube 1 frame at a time.

I think you guys know how to handle the cube in 1 / 2 point perspective.  In 1 point perspective you have two edges that line up at the same depth thus creating a face that's "closest to camera".  From that face the edges converge away.  In 2 point perspective you just have an edge that's "closest" and the lines from there converge as it goes away from that edge.

In the case of a tumbling cube, you're going to have a lot of times where there is only a point that is "closest to cam".  When for whatever reason the face or the edge fits in with the 1 / 2 point perspective on a particular frame, then you'll have to apply those rules accordingly.  But otherwise it'll turn into sort of a 3 point perspective.  This is just through observation though and if it's wrong someone please correct me.  But from that point the edges going away from the camera will converge.

So I think a good rule of thumb to start with would be to determine what is closest to camera and build your edges from there.  In the drawing, the point becomes the main hub, the edges connecting to it become the "center" of the three converging edges.  How do you guys usually go about doing this?

Might try recording a cube in the air and studying that a bit - then probably try animating it again.

P.S. I just realized how redundant our posting-the-dates is.  The blog has the date written as well :)
