bricks_from_table: Convert a table into a 'brickr' 3D object

In brickr: Emulate LEGO Bricks in 2D and 3D

Description

Create a 3D brick object from a data frame. Left-most column is level/height/z dimension, with rows as Y axis and columns as X axis.

Usage

bricks_from_table(
  matrix_table,
  color_guide = brickr::lego_colors,
  piece_matrix = NULL,
  use_bricks = NULL,
  .re_level = TRUE,
  increment_level = 0,
  min_level = 1,
  max_level = Inf,
  increment_x = 0,
  max_x = Inf,
  increment_y = 0,
  max_y = Inf,
  exclude_color = NULL,
  exclude_level = NULL
)

Arguments

matrix_table	A data frame of a 3D brick model design. Left-most column is level/height/z dimension, with rows as Y axis and columns as X axis. See example. Use tribble for ease.
color_guide	A data frame linking numeric .value in matrix_table to official LEGO color names. Defaults to data frame 'lego_colors'.
piece_matrix	A data frame in same shape as matrix_table with piece shape IDs.
use_bricks	Array of brick sizes to use in mosaic. Defaults to c('4x2', '2x2', '3x1', '2x1', '1x1')‘. ’1x1' will always be considered.
.re_level	Logical to reassign the Level/z dimension to layers in alphanumeric order. Set to FALSE to explicitly provide levels.
increment_level	Default '0'. Use in animations. Shift Level/z dimension by an integer.
min_level	Default '1'. Use in animations. Any Level/z values below this value will be cut off.
max_level	Default 'Inf'. Use in animations. Any Level/z values above this value will be cut off.
increment_x	Default '0'. Use in animations. Shift x dimension by an integer.
max_x	Default 'Inf'. Use in animations. Any x values above this value will be cut off.
increment_y	Default '0'. Use in animations. Shift y dimension by an integer.
max_y	Default 'Inf'. Use in animations. Any y values above this value will be cut off.
exclude_color	Numeric array of color ID numbers to exclude.
exclude_level	Numeric array of Level/z dimensions to exclude.

Value

A list with elements Img_lego to pass to build_bricks.

Examples

#This is a 4x2 brick. One level high, 2 x-values (columns), 4 y-values (rows).
brick <- data.frame(
 Level="A",
 X1 = rep(3,4), #The number 3 is the brickrID for 'bright red'
 X2 = rep(3,4)
)

brick %>% 
 bricks_from_table() %>% 
 build_bricks()
 
 rgl::clear3d()
 
#Build on top of each other by changing the Level value.
#This example builds a blue 2x2 brick on top of a red 2x2
brick <- data.frame(
 Level=c("A", "A", "B", "B"),
 X1 = c(3, 3, 4, 4), #3 is red, 4 is blue
 X2 = c(3, 3, 4, 4)
)

brick %>% 
 bricks_from_table() %>% 
 build_bricks()
 
 rgl::clear3d()

#Provide an additional piece_matrix  argument to change the default brick shape.
pieces <- data.frame(
 Level=c("A", "A", "B", "B"),
 X1 = c("b", "b", "p", "p"), #b is brick (default), p is plate
 X2 = c("b", "b", "p", "p")
)


brick %>% 
 bricks_from_table(piece_matrix=pieces) %>% 
 build_bricks()
 
 rgl::clear3d()
 
 
#Provide a custom table of colors 
custom_colors <- data.frame(
.value = c(3, 4),
Color = c("Bright orange", "Dark green")
)


brick %>% 
 bricks_from_table(color_guide  = custom_colors) %>% 
 build_bricks()
 
 rgl::clear3d()
 
 
#Limit the size of bricks used in the model with use_bricks

brick %>% 
 bricks_from_table(use_bricks = "2x1") %>% #Only use 2x1 bricks.
 build_bricks()
 
 rgl::clear3d()
