  • fixed texture coordinates
  • fixed thickness calculation for bezier
  • spelling and some code beauty

v.0.1

  • linear interpolation
  • cosine interpolation
  • cubic interpolation

that's huge! thxs for this!

This is amazing, but can you fix one bug- splines don't work on ATI cards, when PS compiled to 2_0. Just compile PS to 3_0 and it's works on ATI. Also, you need to enable antialiasing by default because without it thin lines looks ugly.

nice! super cool!

These look stunning!
I was about to say moving the renderer on to a 2nd screen seems to stop the effects, but it looks like it's just the mesh subpatch needs reapplying.

Very cool.

this looks very nice.
I copied .fx files to vvvv folder/contributions/effects(root.v4p adding).
and I restarted vvvv.
but no .fx effects added in node browser.
I'm using vvvv45beta30x86. what is problem?

sansui: this contribution is a collection of effects so according to nodes and paths you'll have to place the unzipped content into an \effects directory inside your "contribution" directory which you referenced in the root.

also note that this contribution didn't pack its helppatches correctly so you'll not be able to open them by pressing F1 on the respective .fx nodes but you'll rather have to open them manually from the directory.

sansui 11/06/2013 - 11:29

thanks! joreg.
I knew the instruction about paths. lately, because of reinstalling vvvv, I missed targetting contribution directory in root patch.
now after targetting the folder, it works well.
