Detailed Description

A utility to gather raw geometry from a world.

The utility sends plMsgExtractGeometry to world components and they may fill out the geometry information. ExtractionMode defines what the geometry is needed for. This ranges from finding geometry that is used to generate the navmesh from to exporting the geometry to a file for use in another program, e.g. a modeling software.

Member Enumeration Documentation

◆ ExtractionMode

enum class plWorldGeoExtractionUtil::ExtractionMode

strong

Describes what the geometry is needed for.

Enumerator
RenderMesh	The render geometry is desired. Typically for exporting it to file.
CollisionMesh	The collision geometry is desired. Typically for exporting it to file.
NavMeshGeneration	The geometry that participates in navmesh generation is desired.

Member Function Documentation

◆ ExtractWorldGeometry() [1/2]

void plWorldGeoExtractionUtil::ExtractWorldGeometry	(	MeshObjectList &	ref_objects,
		const plWorld &	world,
		ExtractionMode	mode,
		const plDeque< plGameObjectHandle > &	selection )

static

Extracts the desired geometry from a specified subset of objects in a world.

The geometry object is not cleared, so this can be called repeatedly to append more data.

◆ ExtractWorldGeometry() [2/2]

void plWorldGeoExtractionUtil::ExtractWorldGeometry	(	MeshObjectList &	ref_objects,
		const plWorld &	world,
		ExtractionMode	mode,
		plTagSet *	pExcludeTags = nullptr )

static

Extracts the desired geometry from all objects in a world.

The geometry object is not cleared, so this can be called repeatedly to append more data.
