IrisVirtual

Evaluate your planned Iris setup before making the purchase.

IrisVirtual is a feature allowing you to estimate the number of cameras your project might need, together with their location, orientation and lens type.

The process

  1. Add as many Iris cameras into your viewport as you think you will need and place them as you think appropriate

  2. Map the projection objects to these cameras

  3. Run IrisVirtual which will tell you if your setup is likely to work.

Say, you want to perform a projection mapping on a cave-like projection mapping setup as shown below:

The 3D model was kindly provided by Theoriz.

In the above setup, there are 8 projectors. With IrisVirtual you will be able to get an understanding of how many cameras you should need, which lenses you should choose and where you would need to place them

So to evaluate your planned setup, place Iris cameras in the Viewport and choose the lenses you want to run the evaluation for.

Then, open Iris window and select the Iris camera(s) and all 8 projectors.

When you hit Calibrate button, the process will start

If the result is successful, the Reprojection errors for all of the selected projectors will be below 0.

Interpreting IrisVirtual results

IrisVirtual returns either a positive or a negative result and there are some caveats when interpreting them.

Negative IrisVirtual Results

IrisVirtual can return 2 types of negative results: either reprojection error is above 1 px or the result says “Insufficient number of points”.

The causes can be different:

  1. The camera does not see the entire projected area of the object

  2. The area projected by any one projector is too small when viewed by the camera

Good to know: if in doubt, feel free to contact us and send us your project so that we can have a look at it.

Positive IrisVirtual Result

Positive result means that your Iris setup should work, however please see below:
