silhouette

hi,

sorry, i´ve basic concepts of grasshopper,

there any way to do with grasshopper something like does the command sillouette in rhino?

extract the apparent contour of a surface from a point of view?

the project component gives only the projection of the line that generates the surface or its edge

thanks

I never got around to getting the _Silhouette command to operate inside GH.

I had a go at doing this also, its a kind of single point projection definition that doesn't draw hidden faces based on some simple calculations. Its not perfect but maybe worth a squiz

thanks for your answers,

i think the way is to create a component which includes the order shilouette and run it, something like a rhino script.
is it possible, to call a rhino order as in rhinoscript?

regards

This is possible.

I needed to do it to make a boundary for standard 3-axis CNC undercuts. Having a lot of trouble adding the shadow, though. (The magenta surface was done "manually" in Rhino.)
