Image export size test

Thomthom, interesting to see that you with double the amount of RAM and 64bit OS you can export approx the same max size as I can (with AA). One would think it would be much higher.

Note that since SU is (only) a 32 bit application, it cannot utilize anything that's beyond it.

Since SU is a 32bit application I'm still under the 32bit limitations even though I have a 64bit system...

the old workhorse...

mac 17"powerbook
Processor: 1.33 PowerPC G4
RAM: 1gb
Graphic card and memory: ATI mobility Radeon 9600 64MB
OS: tiger 10.4.11
SketchUp version: 6.4.120 p

Width and height of your maximum exported image in pixels.

9500 x 7055

(in just over 20 minutes )

this pretty much shows the items in the list are irrelevant to image export size... well, except one of the entries

weird thing though: lots of different aspect ratios coming out..
what's dictating that?

[edit] nevermind.. it's just using the same aspect ratio as the sketchup window on whoever's computer. if you really wanted to get into it, everyone should be exporting at a certain ratio instead of locking to their window..

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?

remus · 21 Mar 2009, 08:29

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.

thomthom · 21 Mar 2009, 10:58

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.

Daniel · 21 Mar 2009, 11:39

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.

thomthom · 21 Mar 2009, 12:01

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

thomthom · 21 Mar 2009, 15:10

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 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.

"Creating an Alpha mask of your model for 2D graphic export" http://forums.sketchucation.com/viewtopic.php?f=18&t=26530#p228664

Bon appetit!
