Image export size test
-
So as a little first round up it seems that on Windows no one can export higher than 5650 width.
On OSX its almost twice that with 10000 pixels wide.
Has anyone tried increasing virtual memory in Windows to see what effect that has? -
From a theoretical point of view, i dont think changing virtual memory would help, as the limit is in sketchup itself i.e. SU is maxing out before it can use all the RAM available to it.
-
Don't think it's the RAM. It's the maximum single chuck of memory it can address. If you don't have enough RAM it will page it out to the pagefile, but the limit is how much memory (note: not RAM) windows 32bit applications can handle.
-
I know from experience that virtual memory does make a slight difference. In fact, for this excercise, my office computer had VM set at 6,000 mb and the widest image I could get ws 5,000 - I increassed the VM to 200,000 and was able to get a 5,225 wide image.
I'll admit that most of this computer jargon goes over my head, but looking at my own results I have to conclude that it is a combination of the processors and the video card.
-
I think that the results for PC are ca max 5000-5500px wide with AA on. And I think this is where SU hits the max amount of memory it can allocate on 32bit systems. Variation due to environment differences; aspect ratio, background apps etc.
Had it been hardware we should have seen much larger differences. Not just a few hundred pixels.
What's interesting is that OSX SU exports much larger with AA. Is SU 32bit on OSX as well?

it must be.. the second export i posted is from a laptop i bought in 2003.. pre G5, pre 64bit

That's interesting how the architecture between PC ans OSX allows for different max export sizes. Another argument for SU going 64bit. ...at least compiled with Large Address Awareness marker.

well, if you have the following:
-absolutely nothing to do this weekend
-a test machine
-a knack for experimenting
-understand languages such as "memory_info.BaseAddress = g_last->top_reserved;"then you could mess around with this:

I check 3 out of four. Low level C programming goes swoosh! over my head.

Intel Core2 Quad Q9550 2.83GHz Processor
8.0 G RAM
nVidia Quadro FX 3700 512Mb
Windows Vista 64-bit
SU 7.0.8657
5800x3093 (AA on/Shadows on)-Brodie

I know this is a very old thread by now, but I have found a way getting round these limits and exporting at any size you want.
It is here in the Tutorial forum:
"Exporting 2D graphics with NO size limit" http://forums.sketchucation.com/viewtopic.php?f=18&t=26527
I have also posted a second tutorial on exporting Alpha masks for your 2D exports.

Bon appetit!
