Brad already mentioned this idea at https://lists.w3.org/Archives/Public/www-style/2015Dec/0263.html.
I also have a similar idea to use CSS polar properties as CSS transform function:

Here is the Brad's idea:
transform: polar(angle, distance);

In addition, we could use polar-origin and polar-anchor as CSS transform function:
transform: polar-origin (100%, 50%); /* moves the point of origin to the lower center side of the element.*/
transform: polar-anchor (100%, 0%); /* moves the anchor point of the element to the upper right corner of the element.*/

Using CSS polar properties as CSS 3D transform function:
We could apply the polar properties to CSS 3D transforms. In this case, the polar property should have(r, , ) value as follows:
transform: polar3d (r, , );  /*r: radial distance, : polar angle, : azimuthal angle*/

We could transform the element using polar3d(r, , ) function like the above in a spherical coordinate system.

The polar-origin() function could have z-value to set a point of origin in 3D space:
transform: polar-origin3d(x, y, z);

We could also add  and  to polar-anchor in order to make it work in 3d space:
transform: polar-anchor3d(percentage|length, percentage|length, , );

It would be good to talk about this idea in this CSS WG meeting.
