CSG Rotate
CSG Rotate
csg_rotate( object, pivot_point = c(0, 0, 0), angles = c(0, 0, 0), order_rotation = c(1, 2, 3), up = c(0, 1, 0), axis_x = NULL, axis_z = NULL )
object |
CSG object. |
pivot_point |
Default 'c(0,0,0)'. Pivot point for the rotation. |
angles |
Default 'c(0, 0, 0)'. Angle of rotation around the x, y, and z axes, applied in the order specified in 'order_rotation'. |
order_rotation |
Default 'c(1, 2, 3)'. The order to apply the rotations, referring to "x", "y", and "z". |
up |
Default 'c(0,1,0). Alternative method for specifying rotation–change the new "up" vector. |
axis_x |
Default 'NULL', computed automatically if not passed. Given the 'up' vector as the y-axis, this is the x vector. |
axis_z |
Default 'NULL', computed automatically if not passed. Given the 'up' vector as the y-axis, this is the z vector. |
List describing the triangle in the scene.
