C Specification

The XrSpatialPolygon2DDataEXT structure is defined as:

// Provided by XR_EXT_spatial_plane_tracking
typedef struct XrSpatialPolygon2DDataEXT {
    XrPosef               origin;
    XrSpatialBufferEXT    vertexBuffer;
} XrSpatialPolygon2DDataEXT;

Members

Member Descriptions

  • origin is an XrPosef defining the origin of the polygon. All vertices of the polygon are relative to this origin in the X-Y plane.

  • vertexBuffer is an XrSpatialBufferEXT that provides the ID for a buffer of type XR_SPATIAL_BUFFER_TYPE_VECTOR2F_EXT and represents the vertex buffer of the entity this component is on. The vertices must be returned in counter-clockwise order. The polygon represented by these vertices must not be self-intersecting and may be concave.

Description

XrSpatialBufferEXT::bufferType for vertexBuffer must be XR_SPATIAL_BUFFER_TYPE_VECTOR2F_EXT.
