How do I export with the Full level of Detail for textures

[Gregchop]

Andrea, send me you email so I can share the drop box with you. I would really be interested if your team can make these images work to produce a good mesh of the coin. So far on my end just looks like a round slug

Greg,

all zephyr versions of course have the stereo wizard, otherwise you wouldn't be able to generate a dense point cloud. You're probably referring to the export dense point cloud feature which is available in zephyr pro and aerial only.



As Roberto mentioned, make sure you're exporting the correct textured mesh when comparing in-zephyr rendering with other software. If you wish to increase the resolution for the generation, use the advanced settings as Roberto mentioned as well.

Feel free to send the images over via wetransfer, dropbox shared link or something similar.

OK...after doing some reading, appears only pro has the name Stereo Wizard during the mesh generation, hate to say this but between the 2 of you this is becoming very confusing over a simple question of HOW to preserve the photo quality on the final mesh with texture. Like i said, I am trying to scan a series of coins, since 3DFlow does not do well with close ups regarding mesh, all I have is a slug with questionable texture, since texture is all I have that adds quality to the scan I am just trying to squeeze all I can out. How about I send you a set of IMAGES, and you see what you can get your software to do ? Just let me know where to upload the images too. The images (72) all register, and are very high quality and dont require masking

Hi Gregchop,

those are the window that appear when you are generating the dense point cloud or mesh.

I think you're referring to the export window, but please note Roberto is talking about the generation.

[Gregchop]

yes you are right, where as the coin goes, you basically get a mesh that looks like a flat slug....does feel wasteful of time considering it takes an hour to process and all your left with is a flat slug with zero features...3dflow does not do well on closeups

[Gregchop]

Roberto, no tsure what version you are using but I dont SEE a Stereo Mesh Wizard

[Roberto]

I do not see these sliders you are talking about, please show

You have to switch to "advanced" mode during the stereo/mesh wizard. It's the "resolution" slider.
When using the presets, "default" set the resolution to 25% and high details to 50%

Interesting that the shape of the nose is noticeably different between the two photos. I have an 1883 that looks a lot like yours. It has the eagle with the outstretched wings on the other side. I have several 1922-ish ones and on some of those the nose looks like your second photo. I was thinking about doing photog on the 1883 one but thought the image might be too flat.

Hi Gregchop,

There are no limitations on export. Just right-click on the textured mesh object from the left panel and select Export. From the screenshot, they seem two different objects. Or maybe the texture might have been disabled / not imported into keyshot? I would also try to export in a different format to check if there are problems reading a specific file format.

As for the image resolution, you mean during the processing or the texturing phase? During the densification, the photoconsistency optimization and the texturing there's a slider to control the size of the images (50%, means that the images are downscaled by two both in width and height). Although it might seem counter-intuitive, since all the pictures usually have pixel level noise, I would suggest not to use a 100% resolution during the mvs phase as you might get more noise in the final mesh. During the texturing phase, you can instead increase the slider to 100% and use a higher number of textures (default is 4, but you can increase that number). The drawback is that the final model will be bigger to handle and render.

[Gregchop]

Also what are the settings to get the absolute highest resolution of the images ?

Why do I loose so much detail on export ? Shown is the 3D view in Zypher compaired to External 3d view (In this case Keyshot)
