Pixera Quickstart Guide

This guide is designed to assist users in configuring Pixera to implement warp and blend files generated from a Scalable calibration. Before moving forward, it is assumed that the user has completed a data collection, set up the screen, defined the image boundary, and added an eyepoint (if utilizing 3D export) within the Scalable software.

Scalable Configuration

1. (Optional: Only needed if exporting utilizing the Shader Lamps MPCDI files (Always the case in Atlas)): Navigate to the Scalable dropdown menu in the top left of the screen and follow the path: Support > Advanced Options.

2. Select Add and configure the option: MPCDICoordinateFrameSelector | Int | 1 Select Accept.

3. Navigate to the Exports panel and select the MPCDI 2D, 3D, or Shader Lamps option if you are exporting from SDM. If exporting from Scalable Atlas, you must select the Shader Lamps option. Select Update Calibration.

Pixera Configuration

Prerequisites

1. Screen *.obj file.
2. 2D, 3D or SL profile exported from Scalable Display Manager 10.0 or later. OR an SL profile produced by Atlas 1.5 or later.
3. Pixera Installer Versions: 1.8: pixera_setup_1-8-325.exe or later; 2.0: pixera_setup_1.9-148.exe or later - Link to download: https://pixera.one/en/software/creator

Screens Window

1. Navigate to the Screens window and press the key “G” to enable the Grid. Navigate to the Library tab and expand the Screens folder. Under “custom,” select the custom OBJ that was utilized in the Scalable software, or add it by selecting the “+” symbol at the bottom left of the Library screen.
2. the  Update the settings in the “3D Screen Object Import Options” section of the Screen panel:

• X Rotation = 180 Degrees
• Invert V = Check if inversion of the V Axis of the UV Map is wanted. Unchecked if no change is needed.
• Scale (XYZ) = This should be set so that the W, H, and D values match those of the actual screen.

3. Drag the .obj custom screen from the Library tab into the workspace.

4. Select your screen and update the settings in the “Canvas Resolution”, “World Transformation”, and “Render Settings” sections of the Screen panel, as follows:

• Horizontal and Vertical Canvas Resolution = Matches the size of the content used in playback.
• Position (XYZ) = Set to (0,0,0), adjust as needed.
• Role in Venue = Screen
• Selective Target Rendering = Texture per Screen

Mapping Window

1. Navigate to the Mapping window and select the Library tab. For each projector: Search for and drag into the scene a “Generic Projector”. You can search for your make and model of projector and use that instead.
2. Select each projector and update the following settings under the Projector panel:

• Name = Change the name of each projector. Start with "Proj 0" for Projector 1.
• Automatic Projector to Screen Mapping = Unchecked.
• Properties > Resolution = Set to the resolution of the projector.

3. Change the Selection Mode from "Projectors" to "Screens". This can be done by utilizing the "F4" key or selecting the Selection Mode icon, as seen below, in the top right corner of the toolbar.

4. Select your screen and navigate to the bottom of the Screen panel to load the MPCDI files and assign them to the correct projectors:

• Select Clear Calibration, then proceed to select Load Calibration.
• Choose the MPCDI File path, and assign each projector to its respective region. If your file is an SL MPCDI file, set the Unit Scale Factor to match the value set in the Screens > Scale section.

• If replacing an MPCDI file, restart Pixera.

5. Navigate to the Live tab and select each output. Look to the Output panel and check (select) Active for all outputs.

6. Navigate to the I/O Routing tab to and assign an output to each projector.

Compositing

1. Navigate to the Compositing window, select Media > Standard Content, and drag any clip to the timeline.

2. To loop the content, double-click the strip above your placed content in the Timeline. A “cue” flag will appear; Drag it to the end of the clip, and with it selected, adjust the Operation parameter to Jump in the Cue panel.

3. To adjust the content's coverage on the screen, right-click the Layer, navigate to Scale Unit Mode, and select Stretch to Home Screen.

Updating the .OBJ

1. Open the Scalable software and create a restore point by navigating to Scalable Menu > Configuration > Backup/Restore. Select New. This will ensure you have a saved fallback to go to after uploading the new .obj.

2. Navigate to the Screen Panel and select Import (you will have to navigate to the custom screen type if using SDM ). Choose your new .obj.
3. Select Update Calibration.

4. Go back to the start of the Pixera Configuration section to ensure the new .obj is set up correctly in Pixera.

Troubleshooting

• If Pixera is not reading the MPCDI file correctly: Change the name of the MPCDI file to differentiate it from the name of the MPCDI file currently in use. Selecting “Clear Calibration” before uploading is a key step.
• If the MPCDI file looks off (Example: Alignment issues in Pixera, but not Scalable): Adjust the MPCDI Pixel Pitch Value in the Exports Panel of SDM.

• If the content does not project:
• Restart Presence on remote machines - Shift Esc + F5 on master or Alt F4 on client.
• Navigate to Mapping > Live, select each output in turn, and toggle the Active checkbox.
• Navigate to Mapping > Project, select each projector, and confirm that the preview in the top right corner looks reasonable.
• Navigate to Compositing and click on the media file in use. Click on Assets on the right and select Distribute.
