[opensource-dev] Fwd: Snowstorm Request: Shadow Support for Mac

[Trilo Byte]

I would like to have support for shadows in the Mac client.  I think it would present a more compelling and immersive experience for residents who use Mac, and help draw in new users.

===

I'm not sure if you're a Mac user or not, but the mac client/renderer does not actually work when it comes to shadows.  On any Mac hardware configuration.  I've spent dozens of hours testing on multiple machines, and talked to hundreds of Macintosh SL users (via the in-world Macintosh Users Group and other forums) and come to realize that shadow rendering does not work on any system.

I've also done extensive cross-platform testing on my primary system, a Mac Pro dual processor Xeon workstation w/32GB RAM, an nVidia GTX 285 1GB driving my primary display, and an nVidia GT120 512MB driving my secondary display.  This machine should be more than capable.  Running Windows 7 Professional x64 bit, shadows work just fine using a number of clients, including the SL 2.1 viewer.  Running Mac OS X 10.6, strange artifacts and glitching appears on the screen.

I'm attaching a zip file with three screen shots, showing what the result is in each step while enabling Framebuffer objects, deferred rendering, and then global illumination.  I'm told by Nyx Linden that there may be some tweaks and adjustments that can be made to get this working.

Hopefully this is an easy win.  All of Apple's shipping hardware has been well above "class 0" hardware since early 2009, and all current systems should have the GPU muscle needed to make this work.

Thanks!
