Stack images horizontally — stack_horizontal • scimesh

Stacks a list of rendered images side by side. A convenience wrapper around compose_layout().

Usage

stack_horizontal(
  ...,
  colorbar = NULL,
  colorbar_height = 80L,
  colorbar_width = 80L,
  background = c(0, 0, 0, 0),
  colorbar_side = c("right", "left"),
  crop = FALSE
)

Arguments

...: Images from render_mesh() or render_scene(), or a list of images.
colorbar: Optional colorbar.
colorbar_height: Height of the colorbar in pixels.
colorbar_width: Width of the colorbar in pixels.
background: Background RGBA color for padding.
colorbar_side: Side for the colorbar: "right" (default) or "left".
crop: If TRUE, crop whitespace from the output.

Value

A composed image list.

Examples

mesh1 <- generate_cuboid(c(-2, 0, 0), c(0.5, 1, 1), c(1, 0, 0, 1))
mesh2 <- generate_cuboid(c( 2, 0, 0), c(0.5, 1, 1), c(0, 0, 1, 1))
img1 <- render_mesh(mesh1$vertices, mesh1$triangles)
img2 <- render_mesh(mesh2$vertices, mesh2$triangles)
result <- stack_horizontal(img1, img2)
tmp_file <- tempfile(fileext = ".png")
write_png(result, tmp_file)
