Project Breakdown
I was inspired by modern day footwear advertisements and product rendering and is something I wanted to explore further in 3D.
1. 3D Scanning
Step 1 of the process was to capture both the top and bottom of my shoe as clean as possible within my current limitations. All photos were taking with an iPhone 13 Pro at a fixed shutter speed and ISO in DNG Raw.
2. Reconstruction
Model reconstruction was done in RealityCapture. I first processed the top and bottom separately in order to generate masks that could help when bringing the two halves together. However, as is usually necessary, I had to go in and manually tweak some things. This was a good exercise in learning how to use multiple control points to align both sides of the model. It was a bit tricky due to the angle of the shoe in the bottom side photographs, so there weren't as many clear feature points that were visible from both sides. With the extra attention, I was able to merge the components and create fully closed and textured 3D model.
3. Retopology and Texture Reprojection
The high poly model was retopologized within Instant Meshes with the low poly models vertices reduced to 123k down from 2.2M. With the new low poly model, I projected the textures and normal data from the original high poly model to the low poly model within Reality Capture.
