> Quote - I am curious exactly how do you propose this time coordinate math function isosurfaces be applied to the current crop of poser native females/figures/joints etc??.

The main strength of isosurfaces is that you can define geometry of environment and props etc. using expresions, not with verties and facets. You can compare it with how procedural materials define colour or transparancy without using bitmaps. Resolution of the definition is not an issue because the definition is exact an not an interpolation grid. Scale of the object, depending on how it is defined, can or cannot affect the scale of the object. A typical way of defining a brick wall is to intersect the volume of the wall, say a suitably sized box, with the spatial bricks texture. If you increase the size of the box by a number of brick units, you get, like it should, more bricks in your wall and not, Poser style, a wall with the same number of bricks that are larger.

Complex Solid Geometry between objects by multiplying them (with opposite sign).

The function would not affect the figures directly but be supportive.

The above is of course just a traditional V4 head intersected with a tranaparancy 'spiral'. Poser needs geometry to project the result on. Isosurfaces do same projecting the function into space, and would therefore show enclosed volumes.
