You are going to model something that will be 2D? Or were you going to use
a ready-made photo? If the latter, image_map is all you'd need.
Yes, in the beta of 3.5 and MegaPOV, both have splines. It isn't very
difficult to use at all. Just a list of points (vectors) with a time value
attached to each, then when you run a variable through it via clock or loop
it increments according to that. Interpolating a series of vectors called
by MySpline(Time) for example which in reality is <1,2,3> format as
recognized by the keyword you apply it with, i.e. translate MySpline(Move)
[those words being whatever you declare them to be, of course]. Move would
be the clock or loop variable.
See section 6.1.9 of the v3.5 docs.
I thought that was available online separately but I fail to find it now.
Check out the creators (I think he is anyway) tutorial on it:
