Sphere Object
Sphere Object
sphere( x = 0, y = 0, z = 0, radius = 1, material = diffuse(), angle = c(0, 0, 0), order_rotation = c(1, 2, 3), velocity = c(0, 0, 0), flipped = FALSE, scale = c(1, 1, 1) )
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 |
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". |
velocity |
Default 'c(0, 0, 0)'. Velocity of the sphere, used for motion blur. |
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.
