# Stereo Cine Camera Actor

> Plugin version 1.0.5.4.1, created by[ Christian Alejandro Ordóñez.](https://www.behance.net/chrisalejo3D)

## Introduction

In our studio we had the need to create a stereo camera to render our productions in 3D. Unreal Engine is an incredible tool for the purposes we require for rendering but we needed a camera with the ability to render in stereoscopy, so here we are.

This plugin prioritizes rendering functionality. It's ideal for filmmakers and creators who need to render high-quality stereo 3D content using Unreal Engine. While it might not be suitable for real-time applications within packaged games, it excels in creating stunning visuals for pre-rendered projects.

The plugin utilizes the industry-standard Off-axis method for generating accurate stereo pairs. This ensures a realistic depth perception in your rendered 3D scenes. For further details on the Off-axis method, you can refer to [this site](https://paulbourke.net/stereographics/vpac/theory.html).

## Features

### Camera Active:

**Select Active Camera:** RIGHT, LEFT, or CENTER. This option allows you to switch between the three different views and render the desired view using the sequencer.

### Camera Distance:

**Interpupillary Distance (IPD):** This is the distance between the left and right cameras, which corresponds to the distance between the viewer's eyes.

### Zero Parallax Plane:

The **Zero Parallax Plane** can be adjusted manually or set to any target actor in the scene. This is the plane where objects appear to have no parallax, creating a sense of depth.

**Zero Parallax Plane (Cyan):** This plane defines the point where objects appear to have no depth difference between the left and right eye views. This creates a comfortable viewing experience.

**Stereo Comfort Zone (Red: Far Plane, Green: Near Plane):** These colored planes represent the ideal viewing distance range for comfortable stereoscopic viewing. Objects positioned outside this zone may cause eye strain due to excessive parallax (depth difference). This is a helpful visualization tool for debugging your scene composition.

### Anaglyph Preview (Experimental):

The camera features an **Anaglyph 3D preview** for the viewport from the central camera view. This allows you to quickly check the stereoscopic effect.

### Spline Control Actor:

In addition to its stereo capabilities, the camera can be assigned a **Spline Control Actor** to move the camera along a spline path. This is useful if you want the camera to follow a specific track. It is recommended to use the provided actor for this purpose.
