## Dataset Summary
**microgen3D** is a dataset of 3D voxelized microstructures designed for training, evaluation, and benchmarking of generative models—especially Conditional Latent Diffusion Models (LDMs). It includes both synthetic (Cahn-Hilliard) and experimental microstructures with multiple phases (2 to 3). The voxel grids range from `64³` up to `128×128×64`.
The dataset consists of three microstructure types:
- **Experimental microstructures**
- **2-phase Cahn-Hilliard microstructures**
- **3-phase Cahn-Hilliard microstructures**
The two Cahn-Hilliard datasets are thresholded versions of the same simulation source. For each dataset type, we also provide pretrained generative model weights, comprising:
- `vae.ckpt` – Variational Autoencoder
- `fp.ckpt` – Feature Predictor
- `ddpm.ckpt` – Denoising Diffusion Probabilistic Model
