Spirograph in 3D

[Brian Charles]

Since Write-On uses 2D coordinates, I’m pretty sure that the expression needs to be applied to a particle system with 3D coordinates to make a 3D animation.

In the linked file I created a null named Null: Center as in the script, then I applied the script to the Null’s position property, finally I linked Write-On’s brush position for a 2D Spirograph and Particular’s positions for a 3D one.

The only other way might be to generate the animation in 2D and then wrap it around a sphere using CC Sphere, really pseudo-3D.

Thanks Brian,

Unfortunately I am running CS 5.5 so am unable to open your example. I have recreated my own with the position of Trapcode Particular parented to a null, with the expression copied into the nulls position. The look I am getting is not as per the example, it still appears to operate only in a 2D space.

I just looked at yours and its is 3D, add a camera and rotate it.

Ah! Thankyou!
