Hi,
a bit unsure if this post belongs to a different department, but it is related to the projector module.
I have been trying to set up a simple scene to test out the projector module, and I will give you a short description of the setup.
My patch is basically just a modified version of the help patch.
I have 3 boxes of varying sizes placed on the floor. The front one is placed at 0,0,0.
The projector is placed on the floor, at -2 on the z-axis, this corresponds to 2 meter in my setup.
the second box is about half a meter behind and to the right of the front box, and the last one is about a meter behind and to the left of the front box.
I use a sanyo xu105, and have tried to adjust the parameters for the projector module to fit as close as possible.
One thing I don´t quite get is the lens z depth which is not accessible in the help patch, but which in the projecor patch itself seems to be set halfway into the projector?
Anyway, the projection and the projection match up pretty well after typing in the correct dimensions and distances, except for the box in the back. It is slightly off, I need to adjust the z-value with .11 (corresponding to moving the object 11 cm) to make it fit.
If I try to make the projection fit with the third box, the two other boxes needs to be adjusted .11 on the z-axis.
So no matter what I do, I am not able to get rid of this.
Do you have any suggestions as to why this is happening and how I can deal with it? Obviously I can adjust the position of the box manually for this particular setup, but it would be great to know that the projector module is tuned right for more complicated setups.
thanks,
hc
