Recently I treated myself to a new camera lens for my Yi M1 DLSR camera, the Olympus M.Zuiko Digital ED 60mm f/2.8 Macro lens. This lens can make razor sharp images, from far away and extremely close-up.
So to put this lens to the test of what it can do, I’ve decided to 3D scan another tree bark in the forest near my home. This time it was the Pinus sylvestris (or the Scotch pine).
It was an overcast morning and it hadn’t rained in a while, so it was the ideal time for photogrammetry without the need for a powerful flash to override the natural light. I did use a polarization filter for the first time, which made quite a difference in photo quality.
I made a total of 220 photos, close-ups and average distance photos of the Scotch Pine Bark. Once back at home, I let Meshroom do its thing. The raw mesh was high quality and full of details, the real pain was retopology and UV unwrapping.
But the end result, is stunning!
And as usual, I made this high quality Pinus Sylvestris Bark model, for free. The model is retopologized and has 12K (baked) textures to create a stunning asset for extreme close-up renders.
- Darktable for processing the RAW images
- AliceVision – Meshroom for Photogrammetry
- Instant Meshes for Retopology
- Blender for Sculpting and Texture Baking
- Materialize for creating the missing Textures
- Cycles X (Blender) as the Render Engine
- Affinity Photo for 2D editing (Post Processing and Texture Editing)
