This document provides guidance on configuring and understanding the stereo 3D features in ICEIgloo Core Engine. It covers how to enable stereo 3D settings at the workspace, layer, and window levels. Additionally, it outlines the supported content formats and display output standards for stereo viewing.

...

Layer Stereo Modes

To specify the format of Stereo 3D setting for a particular layer, go to the General tab in the Layer Properties pane. In this tab, you can choose from various supported stereo formats including:

• Mono

• Top-Bottom

• Side-by-Side

Important Note:
Even if If the workspace is not set to Stereo Modein stereo mode, setting a layer to a stereo format will not cause any display issues. The layer will still appear correctly, but it will be rendered in Mono when the workspace is in a non-stereo mode.This added note should clarify that setting a layer to stereo doesn't disrupt the display if the overall workspace is not in Stereo Mode.

...

Window Stereo Modes

To set the stereo output setting for individual windows, you can add the stereoFormat tag to each window definition in the ScreenWindowSettings.xml file. The possible values for this tag are:

...

    </window>
	    <window>
        <winXPos>5760</winXPos>
        <winYPos>0</winYPos>
        <winWidth>1920</winWidth>
        <winHeight>1200</winHeight>
        <startX>0.666666666</startX>
        <startY>0.000000000</startY>
        <subWidth>0.333333333</subWidth>
        <subHeight>1.000000000</subHeight>
		<stereoFormat>1</stereoFormat>
    </window>

Configuring Stereo 3D with multiple displays within a single window (e.g. Datapath FX4)

When using multiple displays (projectors) within a single window, the configuration must include each projector's position, size, and stereo format within the window. Below is an example XML configuration for a window divided into four quadrants, each quadrant representing a separate projector/display segment:

<windows>
    <window>
        <winXPos>0</winXPos>
        <winYPos>0</winYPos>
        <winWidth>1920</winWidth>
        <winHeight>1080</winHeight>
		<displays>
			<display>
				<posX>0.0</posX>
				<posY>0.0</posY>
				<width>0.5</width>
				<height>0.5</height>
				<startX>0.000000000</startX>
				<startY>0.000000000</startY>
				<subWidth>0.50000000</subWidth>
				<subHeight>0.50000000</subHeight>
				<stereoFormat>1</stereoFormat>

Display Configuration Parameters

• posX and posY: Define the position of the display within the window, as a fraction of the window's width and height.

• width and height: Specify the size of the display segment relative to the window's dimensions.

• startX and startY: Determine the starting position of the content to be rendered within the display segment.

• subWidth and subHeight: Indicate the portion of the content to be rendered within the segment.

• stereoFormat: Defines the stereo 3D format for each display.
