Member Function Documentation

DrawDebugGeometry()

void Urho3D::TerrainPatch::DrawDebugGeometry ( DebugRenderer *  debug, bool  depthTest  )

overridevirtual

Visualize the component as debug geometry.

Reimplemented from Urho3D::Drawable.

DrawOcclusion()

bool Urho3D::TerrainPatch::DrawOcclusion ( OcclusionBuffer *  buffer )

overridevirtual

Draw to occlusion buffer. Return true if did not run out of triangles.

Reimplemented from Urho3D::Drawable.

GetLodGeometry()

overridevirtual

Return the geometry for a specific LOD level.

Reimplemented from Urho3D::Drawable.

GetNumOccluderTriangles()

i32 Urho3D::TerrainPatch::GetNumOccluderTriangles ( )

overridevirtual

Return number of occlusion geometry triangles.

Reimplemented from Urho3D::Drawable.

GetUpdateGeometryType()

UpdateGeometryType Urho3D::TerrainPatch::GetUpdateGeometryType ( )

overridevirtual

Return whether a geometry update is necessary, and if it can happen in a worker thread.

Reimplemented from Urho3D::Drawable.

OnWorldBoundingBoxUpdate()

void Urho3D::TerrainPatch::OnWorldBoundingBoxUpdate ( )

overrideprotectedvirtual
