# castle-model-converter (formerly tovrmlx3d)

`castle-model-converter` is a simple command-line program to convert all supported model formats to X3D, and to pretty-print X3D and VRML. It can also be used to validate models.

Note that in simple cases, `castle-model-viewer` can also be used to convert models. Interactively (just open a model, and then use menu items _"File -> Save As..."_) or from command-line (use `--write` and related options). But `castle-model-converter` has a bit more options and at the same time lighter requirements (it does not depend on any GUI libraries).

The documentation of command-line options to perform convertion is on https://castle-engine.io/castle-model-converter .

## Building

Compile by:

- [CGE editor](https://castle-engine.io/editor). Just use menu items _"Compile"_ or _"Compile And Run"_.

- Or use [CGE command-line build tool](https://castle-engine.io/build_tool). Run `castle-engine compile` in this directory.

- Or use [Lazarus](https://www.lazarus-ide.org/). Open in Lazarus `castle_model_viewer.lpi` file and compile / run from Lazarus. Make sure to first register [CGE Lazarus packages](https://castle-engine.io/lazarus).

- Or use [Delphi](https://castle-engine.io/delphi). Open in Delphi project `castle_model_viewer.dproj` file and compile / run from Delphi. See [CGE and Delphi](https://castle-engine.io/delphi) documentation for details.
