此结构中的所有信息都用于描述所需的镜像视图 blit 操作。
XRMirrorViewBlitDesc 可以包含多个 XRBlitParams(仅描述一个 blit 操作)。渲染管线可以通过 GetBlitParameter 查询每个子 XRBlitParams。XRMirrorViewBlitDesc 通常由可编程渲染管线使用。
blitParamsCount | 此 XRMirrorViewBlitDesc 的 XRBlitParams 条目数。 |
nativeBlitAvailable | 当其为 true 时,当前显示子系统支持原生 blit,必须调用 AddGraphicsThreadMirrorViewBlit 来执行原生 blit。 |
nativeBlitInvalidStates | 当其为 true 时,显示子系统将修改图形状态。 |
GetBlitParameter | 获取特定 XRMirrorViewBlitDesc 的 XRBlitParams。 |
