What is the spline’s ‘t’ parameter in http://wiki.synfig.org/wiki/Outline_Layer#Homogeneous ?

Is it the théta of the tangent of the vertex ?

‘t’ is the variable to evaluate the position on the Bezier curve. Synfig uses cubic bezier curves:

en.wikipedia.org/wiki/B%C3%A9zie … ier_curves

and so, the ‘t’ describes one unique 2D point on the curve when it goes from 0.0 to 1.0

-G

Yep genete…

Ok i see, ‘t’ is a current position in the bezier curve between 0 and 1 .

But how to explain that in doc ?

With this kind of explicit image ?

Better, i will link directly to some bezier’s wikipedia page.
