v1 |
Default 'c(1, 0, 0)'. Length-3 vector indicating the x, y, and z coordinate of the first triangle vertex. |
v2 |
Default 'c(0, 1, 0)'. Length-3 vector indicating the x, y, and z coordinate of the second triangle vertex. |
v3 |
Default 'c(-1, 0, 0)'. Length-3 vector indicating the x, y, and z coordinate of the third triangle vertex. |
n1 |
Default 'NA'. Length-3 vector indicating the normal vector associated with the first triangle vertex. |
n2 |
Default 'NA'. Length-3 vector indicating the normal vector associated with the second triangle vertex. |
n3 |
Default 'NA'. Length-3 vector indicating the normal vector associated with the third triangle vertex. |
color1 |
Default 'NA'. Length-3 vector or string indicating the color associated with the first triangle vertex. If NA but other vertices specified, color inherits from material. |
color2 |
Default 'NA'. Length-3 vector or string indicating the color associated with the second triangle vertex. If NA but other vertices specified, color inherits from material. |
color3 |
Default 'NA'. Length-3 vector or string indicating the color associated with the third triangle vertex. If NA but other vertices specified, color inherits from material. |
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". |
flipped |
Default 'FALSE'. Whether to flip the normals. |
reversed |
Default 'FALSE'. Similar to the 'flipped' argument, but this reverses the handedness of the triangle so it will be oriented in the opposite direction. |
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 XZ plane in the scene.
