# rtcGetGeometryUserDataFromScene(3)

### NAME

-

  ```
  rtcGetGeometryUserDataFromScene - returns the user data pointer
    of the geometry through the scene object
  ```

### SYNOPSIS

-

  ```
  #include <embree4/rtcore.h>
  void* rtcGetGeometryUserDataFromScene(RTCScene scene, unsigned int geomID);
  ```

### DESCRIPTION

The `rtcGetGeometryUserDataFromScene` function queries the user data pointer previously set with `rtcSetGeometryUserData` from the geometry with index `geomID` from the specified scene `scene`. When `rtcSetGeometryUserData` was not called yet, `NULL` is returned.

In contrast to the `rtcGetGeometryUserData` function, the `rtcGetGeometryUserDataFromScene` function an get used during rendering inside a SYCL kernel.

### EXIT STATUS

On failure an error code is set that can be queried using `rtcGetDeviceError`.
