C Specification

The XrRenderModelAssetPropertiesEXT structure is defined as:

// Provided by XR_EXT_render_model
typedef struct XrRenderModelAssetPropertiesEXT {
    XrStructureType                         type;
    void*                                   next;
    uint32_t                                nodePropertyCount;
    XrRenderModelAssetNodePropertiesEXT*    nodeProperties;
} XrRenderModelAssetPropertiesEXT;

Members

Member Descriptions

  • type is the XrStructureType of this structure.

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

  • nodePropertyCount is the number of elements in nodeProperties.

  • nodeProperties is a pointer to an application-allocated array of XrRenderModelAssetNodePropertiesEXT that will be filled with the render model asset node properties.

Description

The count XrRenderModelAssetPropertiesEXT::nodePropertyCount must be equal to XrRenderModelPropertiesEXT::animatableNodeCount. If XrRenderModelAssetPropertiesEXT::nodePropertyCount is not equal to XrRenderModelPropertiesEXT::animatableNodeCount as populated by xrGetRenderModelPropertiesEXT, the runtime must return XR_ERROR_VALIDATION_FAILURE from xrGetRenderModelAssetPropertiesEXT.

The node names in the nodeProperties array define the identities of the animatable nodes. Order is significant, in that node states retrieved repeatedly during rendering form a parallel associated array.

Because the number of animatable nodes is fixed per render model handle and retrievable with xrGetRenderModelPropertiesEXT, the two-call idiom for buffer sizing and allocation is not needed in this case.
