Panini Projection

This effect helps you to render perspective views in Scenes with a large field of view. Panini projection is a cylindrical projection, which means that it keeps vertical straight lines straight and vertical. Unlike other cylindrical projections, panini projection keeps radial lines through the center of the image straight too.

For more information about panini projection, see PanoTools’ wiki documentation on General Panini Projection.

Using Panini Projection

Panini Projection uses the Volume framework, so to enable and modify Panini Projection properties, you must add a Panini Projection override to a Volume in your Scene. To add Panini Projection to a Volume:

1. In the Scene or Hierarchy view, select a GameObject that contains a Volume component to view it in the Inspector.
2. In the Inspector, go to Add Override > Post-processing and select Panini Projection. HDRP now applies Panini Projection to any Camera this Volume affects.

Properties

Property	Description
Distance	Use the slider to set the strength of the distortion.
Crop to Fit	Use the slider to crop the distortion to fit the screen. A value of 1 crops the distortion to the edge of the screen, but results in a loss of precision in the center if you set Distance to a high value.
