C Specification

The XrSpatialMeshDataEXT structure is defined as:

// Provided by XR_EXT_spatial_entity
typedef struct XrSpatialMeshDataEXT {
    XrPosef               origin;
    XrSpatialBufferEXT    vertexBuffer;
    XrSpatialBufferEXT    indexBuffer;
} XrSpatialMeshDataEXT;

Members

Member Descriptions

  • origin is an XrPosef defining the origin of the mesh. All vertices of the mesh must be relative to this origin.

  • vertexBuffer is an XrSpatialBufferEXT that provides the ID for a buffer that represents the vertex buffer of the entity this component is on. The position of vertices must be relative to origin.

  • indexBuffer is an XrSpatialBufferEXT that provides the ID for a buffer that represents an array of triangle indices, specifying the indices of the mesh vertices in the vertexBuffer. The triangle indices must be returned in counter-clockwise order and three indices denote one triangle.

Description

The component type using XrSpatialMeshDataEXT must specify the XrSpatialBufferTypeEXT of the vertexBuffer and indexBuffer.
