VIOSO Anyblend VR&SIM and VIOSO Integrate Plus can export warp and blend calibrations to the flight simulator X-Plane 11. We provide a plugin package that lets you easily apply the auto-alignment of your projectors in the output views of the simulator, with supported dynamic warping for motion platforms and eye tracking.

1. In VIOSO Core

1.1. 3D calibration

Perform a camera based 3D calibration with Anyblend VR&SIM or VIOSO Integrate Plus following the workflow from this guide: 3D calibration

1.2. Export Mapping

After a successful calibration of your displays, export your mapping in the VWF format:

• From the menu bar, go to File > Export Mapping
• Select your compound display.
• Select the VWF format.
• Check the 3D box.
• Choose a file name and path.
• Click on Export.

2. In X-Plane 11

1. Prepare X-Plane to use all projectors: run the simulator and enable the monitors in Settings / Graphic menu. Note down the numbers for step 3.
   

   ! check the box ” use non-proportional vertical field of view” to allow asymetric frustrums calculated by VIOSO.

   ! Do not enable Vulkan

2. Download and extract the VIOSO X-Plane plugin package to your plugin directory: %X-Plane-Installation-Dir%\Resources\plugins
3. Configure VIOSOWarpBlend.ini
   1.  [default] calibFile is set to your exported calibration file (.vwf) location.
   2. create a [MonitorX] section for every monitor used. X is the number you denoted in step 1.
   3. put in an empty calibFile= for all unwarped monitors like instructors or panels.
   4. set calibIndex= according to the calibration file (double-click the .vwf to see mappings order).
4. Run X-Plane and your warping and blending will be applied.

3. Limitations

• The plugin uses OpenGL API, you cannot use  Vulkan hardware acceleration in the graphics settings.
• The plugin does not support rendering on multiple GPUs on a single machine.
• 3D Panels on the projection screen: you can enable 3D panel visuals on the screen “Internal: fowrard with 3D panel”, however certain aircrafts force eyepoint offsets to the views which could cause misalignment of the warp and blend.
• External views: like tower and chase cameras are not warped.

4. Example

• Single Server
• 4 Display Outputs
  • 1x IOS Monitor (no warping)
  • 3x projectors 1600×2560 (warping on a spherical screen)
• Benchmark plugin performance avg: 600 us
