# Camera Node
|
||
|
|
|
||
|
|
## Description
|
||
|
|
|
||
|
|
Provides access to various parameters of the **Camera** currently being used for rendering. This is comprised of values the **Camera**'s GameObject, such as Position and Direction, as well as various projection parameters.
|
||
|
|
|
||
|
|
#### Unity Render Pipelines Support
|
||
|
|
- Universal Render Pipeline
|
||
|
|
|
||
|
|
The High Definition Render Pipeline does **not** support this Node.

## Generated Code Example
|
||
|
|
|
||
|
|
The following example code represents one possible outcome of this node.
|
||
|
|
|
||
|
|
```
|
||
|
|
float3 _Camera_Position = _WorldSpaceCameraPos;
|
||
|
|
float3 _Camera_Direction = -1 * mul(UNITY_MATRIX_M, transpose(mul(UNITY_MATRIX_I_M, UNITY_MATRIX_I_V)) [2].xyz);
|
||
|
|
float _Camera_Orthographic = unity_OrthoParams.w;
|
||
|
|
float _Camera_NearPlane = _ProjectionParams.y;
|
||
|
|
float _Camera_FarPlane = _ProjectionParams.z;
|
||
|
|
float _Camera_ZBufferSign = _ProjectionParams.x;
|
||
|
|
float _Camera_Width = unity_OrthoParams.x;
|
||
|
|
float _Camera_Height = unity_OrthoParams.y;
|
||
|
|
```
