ProcessDataGrids
This struct contains additional information for operations on grid based nodes (channels, volumes..).
Usually it is filled by Effex and passed to the processing functions of custom plugin nodes.
The values should never be altered if not explicitly stated.
VecInt3D start
The starting cell coordinate in a multiprocessor context.
VecInt3D end
The ending cell coordinate in a multiprocessor context.
VecInt3D xyz
The currently processed cell coordinate.
unsigned long center_index
The cell coordinate given as an array index. Only used for collocated grids.
std::vector< long > indices
A container of cell indices used for staggered grids. Can be empty!
double frac_c
A volume center fraction telling you how much an obstacle is overlapping the current collocated cell.
double frac_u
A volume fraction telling you how much of an obstacle is overlapping the current staggered cell along the x-direction.
double frac_v
A volume fraction telling you how much of an obstacle is overlapping the current staggered cell along the y-direction.
double frac_w
A volume fraction telling you how much of an obstacle is overlapping the current staggered cell along the z-direction.
double const
If the operating node that has filled this struct uses constraints, then this value gives you the final constraint value.
vector3d physical_position
The currently processed position in physical space.
vector3d world_position
The currently processed position in world space.
vector3d op_result
A result variable that can be changed. Currently only used by custom force plugins.
