Detailed Description

A MetaWorldFragment is the basic building block of the world.

it has its own IsoSurface which is used for rendering. When created, an IsoSurface should be created..The MetaWorldFragment will also contain portals to other MetaWorldFragments for visibility culling (todo).

Member Function Documentation

§ update()

void MetaWorldFragment::update ( IsoSurfaceBuilder * builder )

Updates IsoSurface.

Zero data grid, then add the fields of objects to it.

Member Data Documentation

§ m_bNeedUpdate

bool ParaEngine::MetaWorldFragment::m_bNeedUpdate

protected

whether the grid is modified and needs update in the next draw call.

§ mYLevel

int ParaEngine::MetaWorldFragment::mYLevel

protected

position in y, counted in tile-sizes.

this value is only useful when we are trying to manage a pool of metaworldfragments nearby according to their Y level. so that we can group by height. This is usefully when doing voxel based terrain.
