Adds water layer to the scene, removing the previous water layer if desired.

render_water(
heightmap,
waterdepth = 0,
watercolor = "lightblue",
zscale = 1,
wateralpha = 0.5,
waterlinecolor = NULL,
waterlinealpha = 1,
linewidth = 2,
remove_water = TRUE
)

## Arguments

heightmap A two-dimensional matrix, where each entry in the matrix is the elevation at that point. All points are assumed to be evenly spaced. Default 0. Default lightblue. Default 1. The ratio between the x and y spacing (which are assumed to be equal) and the z axis. For example, if the elevation levels are in units of 1 meter and the grid values are separated by 10 meters, zscale would be 10. Default 0.5. Water transparency. Default NULL. Color of the lines around the edges of the water layer. Default 1. Water line tranparency. Default 2. Width of the edge lines in the scene. Default TRUE. If TRUE, will remove existing water layer and replace it with new layer.

## Examples

# \dontrun{
montereybay %>%
plot_3d(montereybay,zscale=50)
render_snapshot()

# }

#We want to add a layer of water after the initial render.
# \dontrun{
render_water(montereybay,zscale=50)
render_snapshot()

# }

#Call it again to change the water depth
# \dontrun{
render_water(montereybay,zscale=50,waterdepth=-1000)
render_snapshot()

# }
