Just released a simple open-source tool that uses classical ML to blend regions from multiple 3D meshes into new ones
Pick source meshes, paint regions, interpolate in latent space.

Great for learning how ML can work with geometry.

3️⃣ PCA for Generating New 3D Faces (Eigenfaces for Meshes)

Use PCA to reduce the dimensionality of 3D facial data, then generate new faces by interpolating in the reduced space, and then convert it back to the original space for a brand new face.

2️⃣ K-Means for Vertex Clustering by Position and Normals

Use k-means clustering to group vertices based on spatial proximity and normal direction. This helps segment parts of a mesh automatically (e.g., head, torso, limbs).

1️⃣ Linear Regression for "Smart" Driven Keys:
Use linear regression to model the relationship between a driver (e.g., joint rotation) and a driven (e.g., blendshape weight). Instead of setting keys manually, train the relationship using example data and let the model interpolate for unseen values.

Here are some pseudo-code images.
🎯 Modular and easy to extend:
✅ Add constraints with loss functions.
✅ Assign weights to losses for flexibility.
✅ Add new types of losses dynamically.

Perfect for tasks like mesh fitting, alignment, or other approximations

💡 Did you know? Neural network libraries like PyTorch can act as general-purpose approximators without building a network.

Just optimize a tensor with losses to solve tasks such a mesh matching with constraints. Continue on🧵
