  ceiling = TRUE,
  light = TRUE
)

Arguments

leftcolor: Default #1f7326 (green).
rightcolor: Default #a60d0d (red).
roomcolor: Default #bababa (light grey).
ceiling: Default TRUE. Whether to render the ceiling.
light: Default TRUE. Whether to render a point light near the ceiling.

Value

List describing the mesh.
