About L3DT

What is L3DT?

L3DT is a Windows application for generating terrain maps and textures. It is intended to help game developers and digital artists create vast high-quality 3D worlds.

What does it do?

Take the visual tour of features ยป

L3DT does quite a lot. A brief list of features would include:

Generating and editing heightmaps

Generating textures, light maps, bump maps, alpha/splat maps, etc.

3D display

  • Real-time 3D rendering and editing of maps in the Sapphire plugin, as well as support for Terragen, VTP Enviro, and other popular renderers.

Calculations and optimisations

  • An automated calculation pipeline that allows you to queue-up some or all of your calculations, set the relevant settings, and then walk away while L3DT does its thing. No program baby-sitting is required.
  • An automatic disk paging system that supports heightfields up to 128k × 128k pixels in size (16 gigapixels) and textures up to 4M × 4M pixels (16 terapixels). Want to make megatextures? No problem!
  • Support for multi-core processing.
  • A batch generation engine for making multiple map projects automatically.

File formats

    • Image formats, including BMP, JPG, PNG, TGA, DDS, PGM, PBM, PCX and RAW.
    • Mesh files, including DAE (COLLADA), OBJ, X, 3DS, B3D, and TIN (export only).
    • Terrain exchange formats, including TER (Terragen), BT (Virtual Terrain Project), GeoTIFF (import only), and HFZ.
    • Game engine terrain files, including TER (Torque 3D), SD7 (Spring) and HTF (GLScene).
  • Support for more formats may be added by plugins.


  • A graphical interface for performing custom calculations by connecting together multiple 'filters'.
  • Support for scripting using the Python and ZeoScript languages (via the cdPython and ZeoScript plugins).
  • An extensive plugin API that allows developers to directly access L3DT data, perform calculations, load or save files, add new file format options, etc. The source code for many examples are provided.

User support

Please note that some of these features are only available to registered users of L3DT Professional. Please consult the comparison of editions page.
