Convert a 2D LEGO mosaic into a 'brickr' 3D object

Stacks LEGO plates to create a 3D version of the 2D brick mosaics. Height of bricks determined by brightness of color.

bricks_from_mosaic(mosaic_list, mosaic_height = 6, highest_el = "light")

Arguments

mosaic_list	List output from image_to_bricks(). Contains an element Img_lego.
mosaic_height	Number of layers in the 3D image.
highest_el	Brick height is determined by brightness of color. Use highest_el = 'dark' for darkest bricks to have mosaic_height.

Value

A list with elements Img_lego to pass to build_bricks.

Examples

# Import a jpeg or png
 demo_file <- system.file("extdata", "demo_img.jpg",
                          package = "brickr", mustWork = TRUE)
 demo_image <- jpeg::readJPEG(demo_file)

 #Begin with a 24x24 mosaic object
 # \donttest{
 mosaic <- demo_image %>%
    image_to_mosaic(24)
    # }

 #Pass the mosaic object to bricks_from_mosaic() to convert to 3D specifications
 # \donttest{
 mosaic %>%
   bricks_from_mosaic() %>%
   build_bricks()

   rgl::clear3d()
   # }

 #In this image, the background is a light color.
 # Change the 'highest_el' to make dark colors highest
 # Change mosaic height to change the number of layers
 # \donttest{
 mosaic %>%
   bricks_from_mosaic(mosaic_height = 3, highest_el = "dark") %>%
   build_bricks()

  rgl::clear3d()
  # }
