hello, i am a first year digital media student and have just introduced myself to max/MSP. i am working on project right now for my uni assignment and i am trying to create chromakeyed plane in 3D space with 3D cubes spinning around it. i have tried so many things and still it doesn't work as needed and i really need some help and professional advice.
achieve this sort of effect in max/MSP
+ use live green screen video feed
+import it in scene with 3D elements around it
+track the movement of person from live feed and apply these values to trigger 3D elements.
i managed to apply live feed onto a plane as a live texture and import it in 3D space along with the cubes
i also managed to sort out tracking and applying in on movement of 3D cubes
every time i was doing chromakeying the keyed areas appeared as black on my 3D plane. i have to get rid of those black areas and make them transparent. i don't know how to achieve that!
the only problem i am facing is getting my videoplane transparent in 3-d space.
i have explained the process and supported it with patches i was working on in my blog here:
i am very confused and apparently there isn't a teacher in my department who can help me to sort my problem. i have read many forums and tutorials, maybe i am looking in wrong direction, please open my eyes!
