Hello,
The Screenshots section of vvvv.org has quite a few beautiful pictures showing dozens of curved lines like grass or hair or confetti paper strings, whose width and color vary - meaning each line itself may have varying width or color. I have been looking in vvvv for a couple of weeks now and could not find a way to draw a curve of varying breadth or color. I tried Line, all of the Bezier nodes etc. Any hints on how to get started in making curved lines of this type?
you could use the Rope (DX9) node to create lines with a width directly. another method would be using bézier or b-spline nodes to create a set of points describing a nice curve, and then using those points to model a line with a width. i patched a demo for you to clarify:
hej,
many of the screenshots you referred to are done with vertexshaders, which is probably the best way of creating curves w/o using too much performance.
browse the shadergallery, you’ll find something there for sure
the rose shots are previews of one .fx to come, as soon as i find the time to fix the normals…
