Hi Jo: I have read the conditional syntax definitions in the documentation section as well as your related comments in this thread. Is the function of the scalar and bolean nodes to sequentially feed the computer/program a set of solution related theoroms? Are the returned yes, no, and null answers to these questions intended to combine and ultimately yield the required scalars, vectors, variables and constants that will describe the color, geometry, and 3 dimentional logic of the graphic image?
I remember a time befor the HP hand held computer when we did compound trig functions by hand to obtain locations for structural steel connections, and it was hell to spend ones day in a mountain of paper. Then came those little canned programs on a strip of tape that you just plugged in the values and that math jungle suddenly was swept away, and what a relief it was!. To me the solution that I see described in that fellow's tutorial on sand ripples is something that could be given like a tgo but in a clip file, and then I could more easily move on to other problems like getting those ripples into certain defined locations within my graphic geography.
I am mainly suggesting that an archive of TG2 primative shapes such as a cone, a torus, or even possibly some useful curved flat sheets sections be made available in clip file form along with a placement description of setting up all the required nodes to get the shapes/colors on site via masks, displacement, ect. within a default plane of my tgd. I am perhaps shooting in the dark here, but I would like to see TG2 grow into a more useful artistic tool without getting a math induced brain freeze by having to keep track of a mountain of trig functions and the zillions of ones and zeroes in the conditional calculus. Then maybe I can make a picture of mount Fujiama blowing cute little smoke rings.
