Help with GDI method

[Deleted]

I've read the SVPOW tutorial for graphic double integration and want to try it out on my own reconstructions, as well as a few others such as Scott Hartman's skeletals, etc.

But how exactly do I deal with body parts held at non-orthogonal angles, especially parts that are curved?

Do I take the angle and curve into account (slices angled accordingly and the length used for the GDI calculation is the total length along the curve)?



Or do I treat it as if it were straight (orthogonal slices, and length used for calculation as the orthogonal straight-line length of the part) ?



Help would be appreciated.

Standard procedure would be the second one (depending on how erect the neck is, you could do it with horizontal lines and vertically stacked slices), but you should probably use shorter segments to capture the shape better.
The first one could work too though, but you would have to use the right measure of distance between the two lines (since the lines aren’t precisely perpendicular, the distance between their centers might do), so that the length measure you use isn’t overestimated by measuring along the curve and/or off-center.
