Curving SVG

Hello,

I am new to SVG and was wondering if there is a way to draw a curve in SVG without using a control point. For example, if I need to draw a curve from (x0, y0) to (x1, y1) to (x2, y2) where (x1, y1) is at the cusp(top) of the curve, is there a way to do it without defining a control point for (x1, y1)? I tried a polyline but it only draws straight lines and I need them to curve. Please help.

Thank you,
Victor.

You can use arc between points, but best is Bezier cubic

Hi Victor,
I don't know if there is a way to do that. But, what is the problem to use the Bezier curve? You have only to write a code such
<path d="M x0 y0 Q x1 y1 x2 y2" fill="none" stroke="blue" /> and that's all...
Sorry, but I don't know more...
Bye Fable

Hello,

Thank you very much for your replies. I don't mind writing in Bezier format, it's just as I understand the control point is not the actual point where curve would intersect it. So if I have points p0, p1, p2 on which the curve lies, I'd have to find out a point pX according to Bezier format in order that it will be a smooth path p0, p1, p2. Or am I wrong?

Thank you.
Victor.

Hello,

I just want to thank once again for providing that website link. I found what I needed under "Cardinal Spline" topic.

Thanks a lot!
Victor.

Victor,
