snowsultan, in classical mathematics, using Cartesian co-ordinates, there are certain academic conventions which Poser doesn't follow. usually in a 2D graph, x is horizontal and y is vertical. in a 3D graph, the xy plane is usually shown as flat to the ground, and the z-axis is then up and down, orthogonal to (normal to) the xy plane. but these are mere conventions, and there's no harm in the unconventional, within reason ;-) mapps, I'm interested in your tutorials. where can one view them?
