What is an LDM file?
File created by VolumeViz Large Data Management (LDM), a program used to visualize complex volume data sets; contains visualization data amounting up to hundreds of gigabytes in size; used to store large data sets and efficiently render them for real-time display and 3D image generation.
LDM files are used when the entire set of visualization data cannot be loaded into active memory, such as in scientific visualization.
