Hi,
we are using ARToolKit as a base for some RA tests in our lab.
As I make some tests on my own computer, I met some problems as I do not have camera on it...
So I created a program which collect images from the camera and save them into files (for the moment in PPM format, for test purpose).
I also made some modifications in order to allow some of the examples to read video streams from a set of image files rather than from a video capture.
It allow me to make tests even without real camera, and it also allow to replay existing video captures to see improvements for the same video sequence.
My question is : does ARToolKit people interrested by a such modification ?
If yes I can try to make "nice" changes and to submit paches.
I also have a technical question :
I managed to remove all video capture related stuff, apart for the "cparam" values, used to initialize the X display.
In examples code, parameters are build using arParamLoad, arInitCparam and arParamDisp, but the generated parameters seems to be invalid if video capture is not initialized (i.e. no calls to arVideoOpen).
Is there a way to build these parameters by the hand, or even better to build these parameters from the X server ?
Of course the image size is known at this stage and is properly set.
Thank for any answer.
Regards,
