Render Water Layer
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 )
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. |
waterdepth |
Default '0'. |
watercolor |
Default 'lightblue'. |
zscale |
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. |
wateralpha |
Default '0.5'. Water transparency. |
waterlinecolor |
Default 'NULL'. Color of the lines around the edges of the water layer. |
waterlinealpha |
Default '1'. Water line tranparency. |
linewidth |
Default '2'. Width of the edge lines in the scene. |
remove_water |
Default 'TRUE'. If 'TRUE', will remove existing water layer and replace it with new layer. |
