Dataset description

This dataset contains synthetic RGB images of randomised α-LGA crystal structures, including noisy and clean renderings, 3D keypoint and wireframe heatmaps, randomised surface bumpmaps, and ground-truth 3D mesh vertices. It also includes full scene configurations, crystal growth parameters, randomised texture and lighting details, summary statistics, and a predefined training/testing split. Included alongside this are the experimental data (images and manual measurements) and result videos.
