What is an LDM file?

LDM files mostly belong to VolumeViz by Visualization Sciences Group. The LDM file extension is mainly associated with the VolumevizLDM data format used to interactively visualize complex and large datasets that cannot be loaded in memory. Such LDM files are made up of multi-resolution volume images with 2D or 3D dimensions. VolumeViz and Open Inventor leverage the efficiency of the Large Data Management (LDM) API to efficiently render very large datasets as 3D graphics in real-time. The LDM filename extension is also related to PowerDesigner, a Windows-based data modelling software. LDM files created with PowerDesigner contain data models. Ludek Maker, a legacy image editing program used the LDM format to store bitmap images.
