That’s probably not the case nowadays. It downsamples the image if that is Max Size is turned off, but turning it on allows the full definition of the 16000px version to be visible. At least it’s what it seems.
That might be a good idea, but it will make projecting the image into the terrain surface harder. I was thinking of having the max image size possible and project it in one go. Eventually, on renders, I’ll use the full resolution 3Gb image, but for reference having an high quality image in the model is very handy. Turninv Max Size on and off allows working in the model rather fast or rather accurate.
No. The downsampling is an OpenGL limitation. When the max image size is not checked, SketchUp downsamples to 1024 x 1024 pixels. The effect of the checkbox depend on your graphics card. I understand that the maximum today is 4096 x 4096 pixels.
TIG has made an extension that splits large images to these dimensions.
You might be right, but honestly the increase in resolution seems more than 4096, when I turn max size on. The image doesn’t seems that blurry and I’m talking about an image that covers 570m x 375m. I’ll post a screen shot.
The max I could import at this point is 25000px height. I’m trying a bit more everytime.
That is definetly not right. It might be very outdated. I have a plugin action ongoing in the model right now, but I will post the difference I see with max size turned on and off with the high resolution aerial inserted. I believe it goes far beyond 4096, but I might be wrong.
I don’t know if it’s compressed, but I could check if you tell me how. I can also check if it’s running out of memory but I think it’s not. I simply get a dialog stating that the image is invalid and Sketchup is rather quick at telling me that. I don’t feel it’s a memory issue as the system is snappy. GPU has 12Gb and 32GB Ram.
EDIT: These are the properties of the image. At least what I could find that related with compression.
