hi there,

I'm trying to create a texture to be applied to a long, thin box. The
texture needs to consist of alternating black and yellow/orange stripes.
Perhaps a piece of ASCII art would help.

The lines represent the stripes. The area in between them is black. The
stripes should be yellow in the centre and orange towards the edges.

I can create straight horizontal stripes using a combination of a scaled
checker overlaid with a gradient / color_map combination to produce the
orange/yellow tinges - that's straightforward enough. What I cannot figure
out is a way to warp the stripes in the centre so that they have that
"grooved" effect.

I could do it by creating intersections with CSG objects passing through the
box and texturing the intersected areas differently, but this seems like a
pretty horrible, inelegant solution, as I need perhaps 50 or 100 stripes. I
could also of course use a GIF or something, but really I would much rather
try to keep things within the scene files and not use anything external.

I'm reasonably new to POV-Ray, so there may be an obvious answer.

Thanks,

DJG
