looping textures in limit SOP?

Hey,

i use a mouse chop > record chop > limit SOP chain to draw some geometry on the screen.

Is there a way to have the texture coordinates not being streched over the whole lengthening stroke/geometry? Instead I’d like to repeat/mirror the uv cordinates/textures after a certain spatial distance has been drawn.

hope that made sense. Basically it should look like you are unrolling an infinate texture …

cheers

The Resample SOP will give you evenly-spaced points. Then maybe you can use a Point SOP to assign U value based on point number ($PT) times a constant.

Alternately, do a SOP to DAT, then get the length between adjacent points into a new column “length” (Evaluate DAT). Then get the cumulative length into another column (Evaluate DAT), then scale that into a new column that represents U and convert DAT to SOP. You will have to handle the first or last row specially, but that can be done via the Evaluate DAT’s second input containing the formulas.

Hi achim,

just thinking the same thing for this …
