This weekend we play with Photogrammetry

Hi there! this weekend we decided to invest some time to play a bit with Photogrammetry software and wanted to show you the results; it was very fun and educative hope you like it!
We start by making a serie of photos from common objects, the idea is just to test so we use a basic camera and light setup:

After the images are processed by the Photogrammetry software we have a scene that we could load up in any 3D modeling software, we smooth the mesh and usually here you clean the polygon mesh but we just wanted to make a test to see what will be the final results, so we leave them be.

Now we imported the mesh into the engine and added a opacity mask to the material, just to hide the ground texture from the mesh:

Now we add Normal, Specular, Roughness and Ao maps to the material, to make it look even more realistic:

And this is the final result from the process, a good quality mesh with detailed textures in a record time :slight_smile:

HOPE YOU ENJOY :slight_smile:

Awsome stuff! I gotta check that out. What’s the application called that you use? Thanks for sharing that man! Super cool! :slight_smile:

Thanks a lot! I’m glad you like it :smiley: We used Autodesk 123D Catch pc version for capture and Blender for modeling, both free software :slight_smile:

Those look great. Autodesk also has MEMENTO in Beta phase at the moment. Gets better results for larger objects and is also free(for now). Other than that I can recommend Agisoft Photoscan as they have a 30 trial and you don’t have to upload the pictures you do all locally. I have a tutorial up on our YouTube channel.

For anyone that is interested.

Awesome, thanks for sharing! Yeah i have heard about Photoscan, didn’t tried it yet but it looks pretty handsome :smiley:
Regards

Great but how you made pieces of snowflakes on second asset?

Thank you :slight_smile: that effect was achieved with simple Roughness and Ambient Occlusion maps.

@Sadaleus like this :slight_smile:

Cool will use it for sure :stuck_out_tongue:

A while ago I studied Photogrammetry to a degree for my game. The biggest problem for me though was the UV mapping. How do you go about consolidating your mesh and restructuring the UV map so it looks right? Last I tried, the UV map was all over the place. A major mess of sorts. Thanks Mountains.

Hello my tutorial is divided into 4 parts. Part 01 is just scanning. Part 2 is Retopology. Part 3 I cover basic UV mapping and Texture baking Essentially baking the Scanned models texture onto a lower poly model. Have a look at Part 3 but I suggest watching the whole tutorial series as it is less that 45 minutes.
