Head-replacing breath

[lamefun]

Make tyrants have breath that replaced human head with cow head and reduces their vision to this:

Should be only possible to revert with medistation.

I suppose you'd like the antisymmetry of the image to be based on the direction of the tyrant breath?

If yes it would be waaaayyy to performance intensive to have a practical implementation of it, only AAA ames can afford this.

Is computing the angle between A, B and C in 3D, drawing two circles and blurring them so hard :O?

Yes, especially the blurring part as suggested in [1][2][3]

I made blur effect in GLSL once, was OK. If it's still not OK, you can make pre-blurred circles in an image editor. Difference in blur radiuses due to scaling both circles differently shouldn't be too noticable in-game, as with a giant cow head, tunnel vision and a tyrant attacking you, you won't have time to notice that.

As for measuring angle between AB and AC in 3D, you can use magical Microsoft code: just code an angle measurement server in C# XNA, then launch it when UNV server starts, then the server can send measurement requests to it and get the results via IPC. That'd constrain UNV servers to Windows, but it's Windows that is perfect and good for servers, not Linux.

P.S. Also, the blurred colored clouds (if you haven't noticed) in the black area are intentional, are they hard to do too?
