## class csFogInfo

> Information for vertex based fog

### Public Fields

csFog* fog
  The structure describing the fog.
bool has_incoming_plane
  If this is false then there is no incoming plane (the current sector has fog).
csPlane incoming_plane
  The incoming plane (plane of the portal).
csFogInfo* next
  Next in list (back in recursion time).
csPlane outgoing_plane
  The outgoing plane (also of a portal).

## Documentation

> Information for vertex based fog. There is an instance of this structure in the csRenderView struct for every fogged sector that we encounter. It contains information which allows us to calculate the thickness of the fog for any given ray through the incoming and outgoing portals of the sector.

`csFogInfo* next`
  Next in list (back in recursion time).

`csPlane incoming_plane`
  The incoming plane (plane of the portal).

`csPlane outgoing_plane`
  The outgoing plane (also of a portal).

`bool has_incoming_plane`
  If this is false then there is no incoming plane (the current sector has fog).

`csFog* fog`
  The structure describing the fog.
