Round3DPortraits is a new player/target portrait addon designed to blend with the default Blizzard UI elements.
Designed to work well with my UI compilation, Round3DPortraits allows you to either augment the original Blizzard unit frames with 3D portraits or to make other unit frame addons look more like the originals. I have included functionality to anchor the round portrait frames to the PitBull4 player and target frames.
The player portrait is a SecureUnitButton, so it can be used to pull up the player menu and do targeting. I am planning to make it work with click casting as well in the near future, to provide a more seamless experience with Clique.
You can also use the portrait separately, and the configuration options allow you to change the border textures so that the portraits work as a standalone frame. They can be moved, and locked, to any place on the screen. The frames are scalable as well.
You can see screenshots on the Round3DPortraits page.
These are not intended to be full unit frame replacements, but to enhance whatever unit frames you happen to be using.
If you have any other ideas for functionality that would fit, I'd like to hear it.
Thanks, and I hope somebody finds this useful, or at least cool. 8)
