Hi,

I want to create an animation of transparency of a circle. The filled circle should be revealed with angle (not with radius). Transparency should be changed along circumference.
I have search a while in internet but without success. I am newbie in field of 3D graphics.

Thank you
Wojtek

I have sketched some steps of the animation. Black border is only depicted on the image to show the border of the circle. The animation should be continuous from invisible circle to full filled circle.

Is it going to a like a radial wipe for transitions between video scenes? What is the application?

Yes.

For example like the following video

This is a quick and dirty one with only nine segments obviously the more segments the better it’ll look:

One way would be to add a filled (Triangle fan) circle and then add a build modifier to it.
