Image export size test
-
Hi Jan, hi folks.
Shadows on, no problem.
Antialiasing on, which one ? The one in OpenGL preference ? on the one in the export option ? I presume that this is the one you are refering to.
Which file format ? I presume that you want JPG.
Which position for the JPG compression cursor ? Max. quality or min. file size or in between ?
Just ideas.

I've edited first post with jpg compression and shadows.

Without AA: 9500x5180 pixelsI found that when SU failed to export I often had to restart SU in order to successfully export again afterwards.

That might matter. Compressing the image require exptra calcualtiuons. And different compressions methods might give different results.
That would also be interesting to see. If saving to a raw uncompressed bitmap allows you to export larger... -
Made the topic sticky. Will chime in (and test) when back home.
-
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...

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? -
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.
