arduino+processing+firebase using esp826612e &mpu6050

I am doing a simple kinect like project where MPU6050 is used to measure angles the sensor is connected to esp8266-12e which is uploading all angles (pitch,roll,yaw) to firebase. I want to make a meaningful proposition out of it,that is: I would be placing one of the sensor on my hand then, my hand movements should be graphically visible remotely. So, in short I just want to get data from firebase into a 3d animation software can someone explain me how could I do this? i.e get the data from firebase or any cloud and map those values to human body parts.
Now data is getting uploaded onto firebase but, I want to get this data in a processing software i.e map to a human body how could I do this?
I have never worked with any processing software let me know methods for quick prototype development..

I fail to see how this is an Arduino issue. You have data in some repository that is not Arduino-based and you want to use that data on a PC to draw pretty pictures. That is STRICTLY a PC issue.
