## rotate_euler_radian(self, r) {#aspose.threed.utilities.Vector3}

Chain a rotation by Euler angles in radian



```python

def rotate_euler_radian(self, r):
    ...
```


| Parameter | Type | Description |
| :- | :- | :- |
| r | [`Vector3`](/3d/python-net/aspose.threed.utilities/vector3) |  |

### Example 


```python
from aspose.threed.utilities import TransformBuilder, Vector3
import math

tb = TransformBuilder()
tb.rotate_euler_radian(Vector3(0, math.pi, 0))
print(f"Transform Matrix: {tb.matrix}")

```


## rotate_euler_radian(self, x, y, z) {#float-float-float}
