Grid Surface

OmfGridSurface

typedef OmfGridSurface {
    OmfOrient2 orient;
    const OmfRegularGrid2 *regular_grid;
    const OmfTensorGrid2 *tensor_grid;
    const OmfArray *heights;
} OmfGridSurface;

A 2D grid or surface positioned and oriented in 3D space.

Attribute Locations

• OMF_LOCATION_VERTICES for per-corner data.
• OMF_LOCATION_PRIMITIVES for per-cell data.

Fields

orient: OmfOrient2

Contains the position and orientation.

regular_grid: const OmfRegularGrid2 *

tensor_grid: const OmfTensorGrid2 *

Exactly one of these must be non-null, defining a grid with either regular or varied spacing.

heights: const OmfArray *

Optional scalar array giving a signed offset from the plane for each grid corner. If null then the grid is flat.

Methods

omf_grid_surface_init

OmfGridSurface omf_grid_surface_init(void);

Initializes or resets a grid surface struct.
