C Specification

The XrPassthroughLayerMeshANDROID structure is defined as:

// Provided by XR_ANDROID_composition_layer_passthrough_mesh
typedef struct XrPassthroughLayerMeshANDROID {
    XrStructureType          type;
    const void*              next;
    XrWindingOrderANDROID    windingOrder;
    uint32_t                 vertexCount;
    const XrVector3f*        vertices;
    uint32_t                 indexCount;
    const uint16_t*          indices;
} XrPassthroughLayerMeshANDROID;

Members

Member Descriptions

  • type is the XrStructureType of this structure.

  • next is NULL or a pointer to the next structure in a structure chain.

  • windingOrder is the XrWindingOrderANDROID of the mesh triangles. The runtime must use it for backface culling when rendering the mesh.

  • vertexCount is an uint32_t representing the number of vertices in the mesh. When XrPassthroughLayerCreateInfoANDROID::vertexCapacity is specified, the vertexCount must be less than or equal to the XrPassthroughLayerCreateInfoANDROID::vertexCapacity.

  • vertices is a pointer to an array of vertexCount XrVector3f which contains the vertex positions of the triangle mesh.

  • indexCount is an uint32_t representing the number of indices in the triangle mesh. The last indexCount % 3 indices, if any, will not be drawn. When XrPassthroughLayerCreateInfoANDROID::indexCapacity is specified, the indexCount must be less than or equal to the XrPassthroughLayerCreateInfoANDROID::indexCapacity.

  • indices is a pointer to an array of indexCount uint16_t which contains the indices of the triangle mesh.
