Strong work, Luke!

I'm sorry I didn't fill in more of the geometric considerations. Looks like you have them in hand. When the step offset is d, then the 45 degree step travel will be sqrt(2.0) * d. Looks like you have the starting positions parallel which was the intent but I did not specify the mathematics. I didn't know what origin or reference point and direction you would like to use. _______________________________________________ arm-netbook mailing list [email protected] http://lists.phcomp.co.uk/mailman/listinfo/arm-netbook Send large attachments to [email protected]
