So I am afraid I opened a can of worms at the beginning of this long and very active thread ;-)

Yes. But now that you're done bug hunting, it's time for you to upgrade to an 8800GT :)

Certainly, this is overdue and I will not buy anything less than a G80. But I need a whole new machine to host the card and an excellent not too slow widescreen (24") ... Since I have my computers always custom built, I still need to do some research first. But in a month or two, I guess the system will be all new.

Cheers,

Unfortunately NOT!

I discovered a few days ago that the CVS code now breaks the VT display at high zoom BADLY. I have done nothing to my 64k VT's for Earth and 32k for Mars. So this is certainly a new "code-fix" effect!

I'll submit a concise bug report to the tracker, as soon as I got a little spare time. You may contemplate already what it could be... It's really disruptive once the zoom level is high enough (tiles are "vanishing" leaving black squares etc)

Speaking of VT closeups, there's also the issue with VT boundary seams that I reported a bug on a while ago.

NO Idea! She just had the right glance into my direction ;-) and I fell in love with the shape of her eyes ...

This is actually a good little example of the use of layers in GIMP. He he Bob! ;-)

Actually, this granny looks as if she's from northern Burma!? Mandalay region (Shan states...), I would guess.

I just did a cvs build with VS2005 and noticed that the Help OpenGL Info tab contains some more info. Not sure when this started.

Code: Select all

Vendor: NVIDIA Corporation

Renderer: GeForce 8600 GTS/PCI/SSE2/3DNOW!

Version: 2.1.2

GLSL version: 1.20 NVIDIA via Cg compiler

Max simultaneous textures: 4

Max texture size: 8192

Max cube map size: 8192

Point size range: 1.000000 - 63.375000


I wonder if this Max cube map size is what caused the blocks on the older cards.

No, the cube map size has nothing to do with it. The code uses a cube map with 128x128 faces. I think the thing to do is just use dynamic cloud shadows for cube map cloud textures. This is very easy to implement and we don't need to do anything tricky.
