DtVortexPagedTerrainExtension Class Reference

Detailed Description

This extension manages the paged terrain system in Vortex, creating and destroying the terrain producer and interface as needed during application mode changes. It handles efficient terrain collision geometry generation for physics simulation.

Constructor & Destructor Documentation

DtVortexPagedTerrainExtension()

DtVortexPagedTerrainExtension::DtVortexPagedTerrainExtension

(

VxSim::VxExtension *

iProxy

)

Constructor.

Creates a new terrain extension with the given proxy.

Parameters

iProxy

The extension proxy to associate with

~DtVortexPagedTerrainExtension()

virtual DtVortexPagedTerrainExtension::~DtVortexPagedTerrainExtension ( )

overridevirtual

Destructor.

Cleans up terrain producer and related resources.

Member Function Documentation

onApplicationModeChange()

virtual void DtVortexPagedTerrainExtension::onApplicationModeChange ( VxSim::eApplicationMode previous, VxSim::eApplicationMode next )

overridevirtual

Handles application mode changes.

Called at the beginning of the update loop before the new mode is actually set. Used for creating and deleting the terrain producer:

• Creates when previous == editing && next == simulating
• Deletes when previous == simulating && next == editing
• Does nothing otherwise

Parameters

previous	Previous application mode
next	Next application mode

createTerrainProducer()

void DtVortexPagedTerrainExtension::createTerrainProducer ( Vx::VxUniverse * universe )

protected

Creates the terrain producer and adds it to the universe.

The terrain producer's responsibility is to feed the Vortex collision detection with parts and collision geometries that represent the terrain. It performs queries on a terrain database via the paged terrain interface in regions where terrain collision representations are required by the physics simulation.

Also creates the paged terrain interface (DtVortexPagedTerrain) which answers these queries and creates the requested collision geometries from the terrain database.

Parameters

universe

The Vortex universe to add the producer to

deleteTerrainProducer()

void DtVortexPagedTerrainExtension::deleteTerrainProducer ( Vx::VxUniverse * universe )

protected

Deletes the terrain producer and related resources.

Removes the terrain producer and interface from the universe and cleans up resources.

Parameters

universe

The Vortex universe containing the producer
