Camera Coordinate System #24

Open ishitamed19 opened 3 years ago

ishitamed19 commented 3 years ago

Hi! thank you for the implementation :)

  1. I had a doubt about what camera coordinate convention do you follow - is it the OpenGL one (X: right, Y: upwards, and Z: backward) ? If yes, then can you help me on how I can use my own pose matrices (X: right, Y:downwards, Z: forward)?

Will flipping the negative sign of y and z coordinates mentioned here ( #12 ) be sufficient?

  1. Also, are these poses camera_To_world or vice-versa?

TIA
