Perspective Projection Matrix patch
Use this patch to project a 3D object in the shape of a truncated pyramid. The input parameters define a projection matrix where every point inside the truncated pyramid maps in the range [0.0, 1.0] on every axis.
This type of matrix can be passed into a Shader Code Asset. When it is rendered it is typically used for defining the volume of an object in the shape of a 3D truncated pyramid.
Inputs
| Name | Description |
|---|---|
Near | The distance of the near plane from the point of projection. |
Far | The distance of the far plane from the point of projection. |
Horizontal FOV | Horizontal field of view, expressed in degrees. |
Vertical FOV | Vertical field of view, expressed in degrees. |
Output
| Name | Description |
|---|---|
Projection Matrix | The perspective projection matrix generated from the provided inputs. |
Example
The image below demonstrates the difference between perspective volume projection (left) and orthographic volume projection (right).
