Surface

OmfSurface

typedef struct {
    double origin[3];
    const OmfArray *vertices;
    const OmfArray *triangles;
} OmfSurface;

A triangulated surface.

Attribute Locations

• OMF_LOCATION_VERTICES for per-vertex data.
• OMF_LOCATION_PRIMITIVES for per-triangle data.

Fields

origin: double[3]

An offset to apply to all vertices, along with the project origin.

vertices: const OmfArray *

Vertex array.

segments: const OmfArray *

Triangle array. Each row contains the three vertex indices of one triangle, ordered counter-clockwise around an outward-pointing normal vector. Values must be less than the length of vertices.

Methods

omf_surface_init

OmfSurface omf_surface_init(const OmfArray *vertices, const OmfArray *triangles);

Initializes or resets a surface struct.
