# Techviz This guide shows you how to integrate your VIOSO projection calibration into Techviz. ### 1. In VIOSO Techviz processes VIOSO’s native export format **(.vwf)**. You can export the calibration in this format from in VIOSO from free mode or project mode | [**Free mode**](/start/free-mode.md) | [**Project mode**](/start/project-mode.md) | | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | |

  1. Calibrate the projectors in either in:

    1. 2D (for static warping & single viewport), or
    2. 3D (model based for dynamic warping & multi-viewports)
  2. From the menu bar, go to File > Export Mapping
  3. Choose the format (.vwf) and tick the 3D box if applicable.

| ### 2. In Techviz To enable VIOSO warping, you must first create a [VIOSO.ini](broken://pages/z7Wvgl5h0bKFU0e1G0ky) file. Use the following template: 
[default]

;; Specify the full path to your VWF file

calibFile=C:\file.vwf
;; Specify the base matrix, that may vary depending on your display setup

base=[1000,0,0,0; 0,1000,0,0; 0,0,1000,0; 0,0,0,1]



;; Specify the channel indices, for as many channels as the VWF file contains

[A_left_eye]

calibIndex=0

[A_right_eye]

calibIndex=0

[B_left_eye]

calibIndex=1

[B_right_eye]

calibIndex=1

[C_left_eye]

calibIndex=2

[C_right_eye]

calibIndex=2



;; If you want debug logs:

; logLevel=3

; logFile=C:\file.log
You must then enable VIOSO warping in your Techviz configuration file. This is done by adding the following parameters: ``` ## Enable VIOSO warping warping\vioso=1 ## Specify the full path to the VIOSO .ini file we just created warping\vioso\ini=C:\file.ini ## Specify the channel name prefixes, for as many channels as the VWF file contains screen 0\warping\vioso\channel=A screen 1\warping\vioso\channel=B screen 2\warping\vioso\channel=C ## To set the HUD position automatically to the position of the screen corresponding to the given channel name # warping\vioso\hud=B ## For debug: 0 to disable, 1 to enable and skip warping, 2 to enable and perform warping ## This will display the positions of the VIOSO origin (in red), TechViz origin (in blue), and overriding actuals (in green) # warping\vioso\debug=1 The warping will now be applied when you launch TechViz. ``` All of these parameters can be modified interactively, including the .ini file: simply click the “Read configuration file” button in Otrack to apply your changes. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.vioso.com/integration/real-time-engines/techviz.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
