coronas should become smaller when moving further away from them, and should
be visible through transparent objects like pp16s or objects with mask=awd5m

Yes, either become smaller or reduce the opacity with
the distance until they're gone (more realistic I think).

Or maybe both - optional - options are always the best :)

Well the first option is not what coronas do, they do increase with
distance. Well, maybe not increase but they do stay the same size. Real
ones they will fade out until they're gone.

This is becuase people use them as general lights... They are meant for
things like realistic lighting from a sun originally and the sun doesn't
shrink when you move backward. I don't think its likely that they will scan
every object between you and the corona and check its opacity, that's a bit
too much work to do.

Yes, generally they fade as the light source fades with distance or obscurity (through fog, for example). I don't think this should be forced, but having it as an option would be great. Also, I have thought for quite some time that it would be great to have the option of making coronas with or without the "glow" effect, and with or without change in size according to distance. This would allow such things as using a corona to simulate an ActiveWorlds 2.x style sprite.

Actually, the "real" sun does decrease it's visual angle (aparent size) as you back away from it, but the effect is too minute to be noticed due to the sun's huge size and extreme distance from Earth. If you could double your distance from the sun, the width of it's image in your visual field would be cut in half. This, however, is not true of a lense flare effect which in cameras or eyes is a function of the optics more than of the light source.

Thanks for renewing this old thread, it's a very important and necessary
wish.

You're quite welcome. I hope my input may also be helpful in some way.

I also posted a reply to the related message by IHNK dated August 12th of 2002 and titled "coronas" where I want into the math a little bit.
