save_piece_obj: Save Wavefront OBJ files of board game pieces

In piecepackr: Board Game Graphics

Save Wavefront OBJ files of board game pieces

Description

save_piece_obj() saves Wavefront OBJ files (including associated MTL and texture image) of board game pieces.

Usage

save_piece_obj(
  piece_side = "tile_face",
  suit = 1,
  rank = 1,
  cfg = getOption("piecepackr.cfg", pp_cfg()),
  ...,
  x = 0,
  y = 0,
  z = 0,
  angle = 0,
  axis_x = 0,
  axis_y = 0,
  width = NA,
  height = NA,
  depth = NA,
  envir = getOption("piecepackr.envir"),
  filename = tempfile(fileext = "%03d.obj"),
  scale = 1,
  res = 72
)

Arguments

piece_side	A string with piece and side separated by a underscore e.g. "coin_face"
suit	Number of suit (starting from 1).
rank	Number of rank (starting from 1)
cfg	Piecepack configuration list or pp_cfg object, a list of pp_cfg objects, or a character vector referring to names in envir or a character vector referring to object names that can be retrieved by base::dynGet().
...	Ignored.
x	Where to place piece on x axis of viewport
y	Where to place piece on y axis of viewport
z	z-coordinate of the piece. Has no effect if op_scale is 0.
angle	Angle (on xy plane) to draw piece at
axis_x	First coordinate of the axis unit vector.
axis_y	Second coordinate of the axis unit vector.
width	Width of piece
height	Height of piece
depth	Depth (thickness) of piece. Has no effect if op_scale is 0.
envir	Environment (or named list) containing configuration list(s).
filename	Name of Wavefront OBJ object. By default tempfile(fileext = ".obj").
scale	Multiplicative scaling factor to apply to width, height, and depth.
res	Resolution of the faces.

Value

A data frame with named elements "obj", "mtl", "png" with the created filenames.

Examples

    if (all(capabilities(c("cairo", "png")))) {
      cfg <- game_systems("sans3d")$dominoes
      files <- save_piece_obj("tile_face", suit = 3+1, rank=6+1, cfg = cfg)
      print(files)
    }
