Mels is an open source library and component set, written in Delphi, and designed for Embarcadero RAD studio and Lazarus, that allows to include 3D models in your projects in a few clicks, just as any other graphical components.

• Simple shapes: surface, cube, sphere, cylinder, cone, torus and parabola
• Texturing for shapes
• Animated 3D models
• Ray picking, allowing e.g a mouse cursor to know on which part of the model it hovers
• Music player (.wav format)

Mels also provides you a direct access to to the component scene, allowing thus to customize it as you want.

The Mels library supports the following model formats:

• Quake I (.mdl)
• Quake II (.md2)
• Quake III (.md3)

Several plugins exist to export such models from Blender, you may find them on the following websites:

• Quake I (.mdl): https://quakeforge.net/files.php
• Quake II (.md2): https://www.rockraidersunited.com/topic/8175-md2-blender-importexport-add-on-early-release/
• Quake III (.md3): https://github.com/neumond/blender-md3

NOTE several versions of Blender may provide a .md2 importer/exporter natively.

For the beginners, here is also an interesting article about how to create a Quake I model with Blender: https://pnahratow.github.io/creating-models-for-quake-1.html

Mels depends on the following third-party libraries to compile:

• OpenGL
• OpenAL
• Glew

For Lazarus, the following module is also required:

• Generics.Collections

A copy of these libraries was added to the project, you can find them in the Library\Prerequisites\ folder.
