List of dependencies

MeshLib is modular by design. Our goal is to provide only what you need, so you can avoid what you do not and keep your project lightweight. The only mandatory module is MRMesh. All others are optional.

Below is a summary of all modules and their dependencies, so you can see what each requires before including it in your build

Module	Task	Required modules	Optional?
MRMesh	Core geometry	-	No, Mandatory
MRIOExtras	Input/Output	MRMesh	Yes
MRSymbolMesh	Text-to-mesh	MRMesh	Yes
MRPython	Python	MRMesh	Yes
MRVoxels	Volumetric	MRMesh	Yes
MRCuda	GPU acceleration	MRMesh and MRVoxels	Yes
MRViewer	Rendering and user interface	MRMesh, MRVoxels, MRSymbolMesh and MRIOExtras	Yes
