label |
Text string. |
x |
Default '0'. x-coordinate of the center of the label. |
y |
Default '0'. y-coordinate of the center of the label. |
z |
Default '0'. z-coordinate of the center of the label. |
text_height |
Default '1'. Height of the text. |
orientation |
Default 'xy'. Orientation of the plane. Other options are 'yz' and 'xz'. |
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 text in the scene.
