C Specification

XrSceneMeshIndicesUint32MSFT is an input/output structure for reading 32-bit indices from a scene mesh buffer.

typedef struct XrSceneMeshIndicesUint32MSFT {
    XrStructureType    type;
    void*              next;
    uint32_t           indexCapacityInput;
    uint32_t           indexCountOutput;
    uint32_t*          indices;
} XrSceneMeshIndicesUint32MSFT;


Member Descriptions
  • type is the XrStructureType of this structure.

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

  • indexCapacityInput is the capacity of the array, or 0 to indicate a request to retrieve the required capacity.

  • indexCountOutput is a pointer to the count of indices, or a pointer to the required capacity in the case that indexCapacityInput is 0.

  • indices is an array of triangle indices filled in by the runtime, specifying the indices of the scene mesh buffer in the vertices array. The triangle indices must be returned in counter-clockwise order and three indices denote one triangle.

  • See Buffer Size Parameters chapter for a detailed description of retrieving the required indices size.
