## Frustum class

The base class of [`Camera`](/3d/python-net/aspose.threed.entities/camera) and [`Light`](/3d/python-net/aspose.threed.entities/light)



**Inheritance:** [`Frustum`](/3d/python-net/aspose.threed.entities/frustum) → 
[`Entity`](/3d/python-net/aspose.threed/entity) → 
[`SceneObject`](/3d/python-net/aspose.threed/sceneobject) → 
[`A3DObject`](/3d/python-net/aspose.threed/a3dobject)



The Frustum type exposes the following members:

### Properties
| Property | Description |
| :- | :- |
| [name](/3d/python-net/aspose.threed.entities/frustum/name) | Gets or sets the name. |
| [properties](/3d/python-net/aspose.threed.entities/frustum/properties) | Gets the collection of all properties. |
| [scene](/3d/python-net/aspose.threed.entities/frustum/scene) | Gets the scene that this object belongs to |
| [parent_nodes](/3d/python-net/aspose.threed.entities/frustum/parent_nodes) | Gets all parent nodes, an entity can be attached to multiple parent nodes for geometry instancing |
| [excluded](/3d/python-net/aspose.threed.entities/frustum/excluded) | Gets or sets whether to exclude this entity during exporting. |
| [parent_node](/3d/python-net/aspose.threed.entities/frustum/parent_node) | Gets or sets the first parent node, if set the first parent node, this entity will be detached from other parent nodes. |
| [rotation_mode](/3d/python-net/aspose.threed.entities/frustum/rotation_mode) | Gets or sets the frustum's orientation mode
<br/>This property only works when the [`Frustum.target`](/3d/python-net/aspose.threed.entities/frustum#target) is null.
<br/>If the value is [`RotationMode.FIXED_TARGET`](/3d/python-net/aspose.threed.entities/rotationmode#FIXED_TARGET), the direction is always calculated by the property [`Frustum.look_at`](/3d/python-net/aspose.threed.entities/frustum#look_at)
<br/>Otherwise the [`Frustum.look_at`](/3d/python-net/aspose.threed.entities/frustum#look_at) is always calculated by the [`Frustum.direction`](/3d/python-net/aspose.threed.entities/frustum#direction) |
| [near_plane](/3d/python-net/aspose.threed.entities/frustum/near_plane) | Gets or sets the frustum's near plane distance. |
| [far_plane](/3d/python-net/aspose.threed.entities/frustum/far_plane) | Gets or sets the frustum's far plane distance. |
| [aspect](/3d/python-net/aspose.threed.entities/frustum/aspect) | Gets or sets the aspect ratio of the frustum |
| [ortho_height](/3d/python-net/aspose.threed.entities/frustum/ortho_height) | Gets or sets the height when frustum in orthographic projection. |
| [up](/3d/python-net/aspose.threed.entities/frustum/up) | Gets or sets the up direction of the camera |
| [look_at](/3d/python-net/aspose.threed.entities/frustum/look_at) | Gets or sets the the interested position that the camera is looking at. |
| [direction](/3d/python-net/aspose.threed.entities/frustum/direction) | Gets or sets the direction that the camera is looking at.
<br/>Changes on this property will also affects the [`Frustum.look_at`](/3d/python-net/aspose.threed.entities/frustum#look_at) and [`Frustum.target`](/3d/python-net/aspose.threed.entities/frustum#target). |
| [target](/3d/python-net/aspose.threed.entities/frustum/target) | Gets or sets the target that the camera is looking at.
<br/>If the user supports this property, it should be prior to [`Frustum.look_at`](/3d/python-net/aspose.threed.entities/frustum#look_at) property. |


### Methods
| Method | Description |
| :- | :- |
| [`remove_property(self, property)`](/3d/python-net/aspose.threed.entities/frustum/remove_property/#aspose.threed.property) | Removes a dynamic property. |
| [`remove_property(self, property)`](/3d/python-net/aspose.threed.entities/frustum/remove_property/#system.string) | Remove the specified property identified by name |
| [`get_property(self, property)`](/3d/python-net/aspose.threed.entities/frustum/get_property/#system.string) | Get the value of specified property |
| [`set_property(self, property, value)`](/3d/python-net/aspose.threed.entities/frustum/set_property/#system.string-system.object) | Sets the value of specified property |
| [`find_property(self, property_name)`](/3d/python-net/aspose.threed.entities/frustum/find_property/#system.string) | Finds the property.
<br/>It can be a dynamic property (Created by CreateDynamicProperty/SetProperty) 
<br/>or native property(Identified by its name) |
| [`get_bounding_box(self)`](/3d/python-net/aspose.threed.entities/frustum/get_bounding_box/#) | Gets the bounding box of current entity in its object space coordinate system. |
| [`get_entity_renderer_key(self)`](/3d/python-net/aspose.threed.entities/frustum/get_entity_renderer_key/#) | Gets the key of the entity renderer registered in the renderer |
