Hi!
I don't have to much knowledge about the math I need. So I hope my
explanation what I want to achieve is right.
I want to use a curve-function (f.e. a cubic-bezier) which is defined
through points laying in the x,y-plane (2D-curve) in a function for a
texture. Where the curve runs, the function should give back 1 and it
should have a fallof described through a factor f (fallof maybe like when
using an airbrush) so the function gives back 0 when the texture-point to
be calculated is away f.e. 0.01 povray-units.
If 1 povray-unit would be 1 meter, this function should draw a texture which
would be a line defined by the points of the bezier-curve and a fallof to 0
in a distance of 0.01 units to both side of the curve.
The goal would be, that one could just draw text using a bezier-curve for a
letter in a program, export the points, and by just putting the point-list
in to the povray-function could use the drawn-text as texture.
I hope it's not do difficult.
Greetings
Dieter
