Crashes with large images.

I assume by the half decade since last update, it will no longer be updated to support larger images?

@DuckersMcQuack The add-in is definitely in need of an update! But is the large image limitation with the add-in or for Fusion? With last testing, it was Fusion that had the limitations. Also, what size images are you wishing to use? Cheers!

@hanskellner The image i wished to use was 6000x1500. Or as large as i have ram/vram for. As i got 64GB ram and 24GB vram. But the tool crashed, as in white screen and no response after that until i restarted fusion.

You wouldn't know of a different program/method to achieve just "image to plane height map"? As i'd then throw it into blender, select pixels around, and add a simplistic square surface to 3d print.

@DuckersMcQuack To clarify, does the crash occur in the Image2Surface add-in or within Fusion once you've sent the image to it? From the tests I've done, it's the expense within Fusion of converting a large mesh to a T-Spline. And that's when I have had crashes or had to terminate Fusion.

Note, the process of creating a T-Spline from a mesh allows for a nice surface for 3D printing. And if you've reduced the mesh density, the T-Spline conversion brings back some of the detail. So you might be able to scale your image down to a smaller resolution and then see if it converts cleanly to a T-Spline in Fusion. Also, when you add your image to the Image2Surface add-in, you may also try changing the stepover value to skip pixels to reduce the density.

I don't have a recommendation for other tools.

First image i loaded image. If i wait too long, it freezes, and eventually turns white screen. Fusion worked otherwise fine. Tried a second time to load image and click generate immediately, then fusion crashed.

@DuckersMcQuack ok, let me do some further testing. This is a new issue to me. Thx.

@DuckersMcQuack -

I did testing with the current version of Fusion (as of this post's date) on my MacBook Pro M1. I created a 1600x1500 image using a photo I captured of the moon (attached). Using the Choose File button, I selected the image file. It opened and displayed in the add-in without delay. I then adjusted the Max Height setting to 20. Finally, I clicked the Generate Surface button. The surface was quickly generated and displayed in Fusion. I also tested a few other large images and had similar results.
