How can we access the camera in XTK?
r.camera.view is a 4x4 matrix
X.camera3D
r.camera.view is a 4x4 matrix
X.camera3D
r.camera.rotate([1, 0]);
rotates 1 degree in x
Let's try it!
c.center = [0, 0, 0];
c.center = [10, 0, 0];
c.transform.translateX(10);
X.cube
from the origin
c.center = [20, 0, 0];
c.center = [10, 0, 0];
c.transform.translateX(10);
c.transform.translateX(-10);
from the current position
