About the degree of rotation, clockwise or counterclockwise? #19

Hello, Thanks for your excellent work! I have a question about R and K. When we get R by get_K_R() and I think R is camera to world matrix not world to camera matrix, is it correct? I think the default rotation direction is counterclockwise. However, when i run the demo.py, the results are images by clockwise. Can you tell me the reason?

For example, if I set the degree of rotation to 45,90, then the camera should rotate 45 degrees and 90 degrees counterclockwise around the y-axis, but I see that the two generated images rotate clockwise.

My understanding is that the default direction of the rotation matrix is ​​counterclockwise rotation, which is a positive value.

Thanks a lot!
