Hi Cyrille,
you wrote:
what i usualy do, is : -put points in a table -interpolate between this points in an other bigger table (using tabread4 / tabwrite for a simple and slow solution) -draw the big table with a vertexbuffer
It's very interesting. Do you have sample patch for this?
i just made one, in attachement
i don't like the look of tabread4 interpolation, but you can make an other cubic interpolation for smoother result.
cheers, Dario
PS: your work Egregore is fantastic
thanks
cheers c

So high order Bezier curve are not very common. the curve object compute the interpolation by the GPU, so the limit is a hardware limit (the "GL: invalid value" is a hardware error, not a Gem one). Usually, people prefers splines. According to wikipedia, the most common spline is cubic B-spline : a piecewise 3rd order Bezier curve. unfortunately, there is no "spline" object in Gem. what i usualy do, is : -put points in a table -interpolate between this points in an other bigger table (using tabread4 / tabwrite for a simple and slow solution) -draw the big table with a vertexbuffer cheers C Le 09/02/2017 à 23:13, Federico Camara Halac a écrit : Hi, I’m on OSX 10.11.6, Gem working (via deken) When rendering is on, this prints out “GL: invalid value” to the console: [gemhead] | [curve 11] (or any number above 10) The curve object with its inlets create accordingly, but there is nothing displaying on the gemwin.
