General / Re: Agisoft Metashape 1.7.0 pre-release
« on: December 08, 2020, 04:34:58 PM »
version 1.7.0 build 11539.

got some inaccurate results in depthmaps generation. not sure if results from to less image overlap or something else.
Input: 57x  16bit tif files from 61mp raws. 24mm g-master lens.

Hello Exorbitart,

Is it possible to share the complete image set and related project with alignment results to support@agisoft.com?
Also have you checked if 1.6.5 results are better? Probably the surface itself has some reflections which affect the reconstruction results.

Hello Alexey,
I send you some example phtos, the report and the resulting maps that represent the output model. The full project is to big to send (66GB).
Hope you can see anything that help to clarify the issues.

thanks,Benjamin

Feature Requests / Re: displacement/ height map baker
« on: October 04, 2020, 06:19:42 PM »
We've developed a standalone app just for this purpose and it does help a lot when dealing with these resolutions. Not a trivial amount of development is required though :)

Where I can find it?

+1 ! Would be awesome !
Best case: possibility to bake displacement/normal maps from HQ mesh to lowpoly meshes (special: +including quadretopo) :) :o 8)
Would be a gamechanger for the 3d assets industry!

If this happen  I would by the professionell edition immediately !!

Hello Exorbitart,

Is there any reason why you are using Disabled blending mode? I think it causes the visible seams between different parts.

That was the problem, didn't know why I disabled it  :-X ::)..
You can delete the topic if you want.

General / Issue with Texture stitching
« on: March 26, 2020, 10:21:38 PM »
In last time I got more and more problems with my generated textures.
looks like that the camera calibration or texture processing is not correct working. Some of the photos are to dark and generate problematic terrace effects.

Strange is that my camera and MS standard settings was working since 3 months:

Camera mode: manual with fixed aperture, iso, shutter etc.

Any ideas?

Bug Reports / Incorrect Alembic export from Metashape ?
« on: February 27, 2020, 05:41:52 PM »
Hello,
luckily the alembic format is a fast export format for highpoly models.

I experimented with it and saw unfortunatly that the meshes at 100mio+ polygons have a incorrect structure or something is wrong (polygon normals?) It is only visible in the normalmaps, shading and AO Pass. Depthmaps are looks ok and the mesh in open GL mode too. (cinema 4d /corona render)


With decimated meshes like 30mio there is not this issue.

Is there a bug in the alembic export from metashape?
Would be happy to use this format right. Any ideas?

Thanks in advance for a hint!?

Metashape 1.6.1 standard/pro  -windows.

Bug Reports / Re: FBX export ultra slow on Windows !!

I tried alembic export it works mutch faster. just few minutes to export a 300mio model

« on: February 25, 2020, 12:44:23 PM »
 just my experiences.:
I export 130mio fbx with current version in ca 1h but this is nearly the limit. obj support better export within 300-400mio polygons but in this ranges it need always 1-2h+ to export (I have 128gb ram).

A automatic tiled mesh via metashape would a big step for users in future!  ;)

To generate a 300mio mesh is not that big challange throught depthmaps.. but the export and further handling in one file is.

Feature Requests / Re: Ultra high normal map on lower res model
« on: February 21, 2020, 07:18:23 PM »
Thank you Alexey, I'll try it!

*push
no one have an idea?

Short again:
I want to bake or generate details from highpolymesh into a normal map/depthmap in metashape.....

Thanks in advance for some recommendations.

Feature Requests / Re: Ultra high normal map on lower res model
« on: February 20, 2020, 03:39:38 AM »
sorry for digging out this 7 years old topic.

but is it now in the pro version possible to generate normal/depth maps from highpoly scan to use it on dezimated meshes?

Would be awesome and I cant find any more info here in the forum.

thanks,
ben

Hello folks,
one more question from my side for texture building workflows:

I want to have the task "Texture type"(ao,normal occlusion) and "source data" in my batch processing workflow.

 I'm blind or there is only a manual walkthrough? Can't find it in the batch options... ::)

What I exactly plan to do is in theory following:
 
1.Build highres mesh like 500mio polygons from depth
2. bake textures from this hq mesh to normal and ao - to get the detailed mesh informations
3. decimate mesh to 99mio for better handling (keep uvs)
4. get hopefully a 99mio mesh with normal/occlussion maps from the 500mio poly mesh (source data thing?)

I read in the manual that should be possible:

"Source data
Images - allow to build a color texture map (diffuse map) based on the aligned images of the model
or transferred from another model with already generated color texture map.

3D model !: - the normal and occlusion texture maps can be built based on another model and the
relief of the model specified in the Source data field will be transferred to the current model. Usually
it is recommended to use the more detailed model as a source data for the Normal and Occlusion map
generation for the 3D model with the lower polygon count. Normal map option will not be available
in the Source data field, if less than two 3D model instances are present in the active chunk."


How I can realize it with a batch workflow? possible?
(using standard edition)

Thanks in advance!  :)
Ben

General / Re: Generate and export only depth maps as greyscale images
« on: February 12, 2020, 11:34:10 AM »
Depth maps in MS are for each photograph (which includes the perspective of every image), to get a proper displacement map out of the whole surface you need to build the mesh.

that was my question, it should be possible to get out the whole depthmaps as one stitched map beside normal and ao map it would make the texture building process much easier for us.

Hello Ben,

If you wish to save the depth maps that are stored in the project and no render depth based on the mesh model, you can use Python scripting in Professional edition. Some time ago I think I have posted an example on forum, let me know if you are interested and cannot find it - I'll re-post it here.

Hello Alexey,
thanks for you reply and offer. It would be kind if you can post it again. Maybe a reason to change to the pro version.

thanks,
ben
