# Need this type of sine wave animation without the cuts as like it is a wire. How to make?

The answer you posted was similar to the required animation by me. But The spline is in square shape, I need a circular one. Can u help me with that.

and also how can we decrease the speed or increase the length of the spline.

• What cuts? Do you want a continuous spline? – Omar Emara Jun 12 '19 at 9:51
• yes, i need a continous spline. – Brahmdeep Singh Jun 12 '19 at 10:53
• Use the Spline From Points node. – Omar Emara Jun 12 '19 at 10:57
• ok, then can i use the above method to animate it? – Brahmdeep Singh Jun 13 '19 at 6:41
• Yes, extract the locations of your matrices and use them as the input vectors of the node. Just like the example in the documentation. – Omar Emara Jun 13 '19 at 7:24

$$\begin{bmatrix} p\\ \alpha p \sin({\beta t + p}) \end{bmatrix}$$
Where $$\beta$$ and $$\alpha$$ are arbitrary constants, $$t$$ is the time, and $$p$$ is the parameter. We can implement this in Animation Nodes as follows:
• @BrahmdeepSingh Increase the value of the Bevel Resolution in the Curve Object Output node to get a circular shape. Change the values of $\beta$, $\alpha$, and the end value of the range node, see what they will produce. – Omar Emara Jun 13 '19 at 12:22
