Photogrammetry - Sponge Applicator

Work In Progress / 08 January 2019

More photogrammetry experiments using Reality Capture this time on a 10 cm diameter sponge applicator. Notice the small wire that I used to balance the object in the air for photo capture. 😲 I'm impressed by the amount of detail that is picked up on such a small object without using a macro lens or tube. In this instance, I used my usual fixed 50mm lens but this time I had the photos focus stacked before feeding them into Reality Capture.  You can do the focus stacking in Photoshop (slower & more cumbersome) or in focus stacking software such as Helicon Focus or Zerene Stacker.


Photogrammetry - Spray Bottle

Work In Progress / 01 January 2019

I'm doing some R&D for a possible upcoming job.  The goal is to cut down production time for building out the assets.  I'm testing Reality Capture this time on a slightly reflective object.  If you're familiar with photogrammetry, you'll know that reflective objects are a pain to capture.  I think the results came out great.

I'm using the same method I used on a previous job where I used a matte gray primer to coat the object then adding some detail using an old toothbrush to flick some paint onto the surface.  Use this method at your own risk! 😉



Photogrammetry - Firewood

Work In Progress / 22 December 2018

Doing some photogrammetry exercises using RealityCapture for data processing, Zbrush for scan cleanup and editing, Maya for retopo, and Substance Painter for texturing.  I've found that adding some micro detail via a height map that's blended in combination with the baked normal map helps to punch up the detail a little.  Here's a side by side comparison with and without.
