I have created a Rigged human hand in Blender, which I now want to manipulate by reading the input stream from Arduino.
I can load the obj file in OpenGL, but I don’t know what should I do next.
Any suggestions are much appreciated
Rigging typically just means you’ve got it ready to animate. Have you modeled any skeletal animations for it? What do you want to do with it on the Arduino?
Re OBJ file format, this isn’t expressive enough to use for skeletal animations (link, link). Depending on what you want to do with this rigged hand, you may want to read up on 1) other model formats, 2) some exporters which handle exporting the skeletal bindings (joints/bones) with the model as well as the animations, as well as 3) skinned animation techniques.
Here’s one tutorial that uses OpenGL, Blender, and Assimp for import to perform skeletal animation:
