Sphere Object

- x
Default `0`. x-coordinate of the center of the sphere.

- y
Default `0`. y-coordinate of the center of the sphere.

- z
Default `0`. z-coordinate of the center of the sphere.

- radius
Default `1`. Radius of the sphere.

- material
Default

`diffuse`

. The material, called from one of the material functions`diffuse`

,`metal`

, or`dielectric`

.- angle
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".

- flipped
Default `FALSE`. Whether to flip the normals.

- scale
Default `c(1, 1, 1)`. Scale transformation in the x, y, and z directions. If this is a single value, number, the object will be scaled uniformly. Note: emissive objects may not currently function correctly when scaled.

Single row of a tibble describing the sphere in the scene.
