... well, I suspect it is. What's the 'classic' function for a triangle?
Oh, here's mine:
max(abs(x) + (max(y,0)-1), y*-1)

I have no clue but I hope you don't want to render meshs with isosurface
triangles ;-)

Heh - not quite. A 3d version of a child's drawing of a house. Using a iso
means I can get some nice wobbly edges and reuse the function for the
pigment.... and, no, you don't get a prize for guessing which part of the
house I need a triangle for.

IIRC there's a f_triangle in MegaPOV.
HTH,

f_triangle written in SDL is available in iso-csg. It can be also hardcoded in
custom builds (MegaPOV) as described at
http://www.abx.art.pl/pov/patches/f_triangle.php

Hmm, looking at the code in the iso_csg include, maybe my function isn't so
bad after all. I dunno - I just expected there to be a basic right-angle
triangle function of some elegance (like, say, the sphere function). At any
rate, something a little more elegant than my solution.

Ow.
I can't help but think how much more painful that'd've been had Marc's
name actually been Luke instead.
