render_snapshot: Render Snapshot of 3D Visualization

Description

Either captures the current rgl view and displays, or saves the current view to disk.

Usage

render_snapshot(filename, clear = FALSE, title_text = NULL,
  title_offset = c(20, 20), title_color = "black", title_size = 30,
  title_font = "sans", title_bar_color = NULL, title_bar_alpha = 0.5,
  image_overlay = NULL, vignette = FALSE,
  instant_capture = interactive(), bring_to_front = FALSE, ...)

Arguments

filename

Filename of snapshot. If missing, will display to current device.

clear

Default `FALSE`. If `TRUE`, the current `rgl` device will be cleared.

title_text

Default `NULL`. Text. Adds a title to the image, using magick::image_annotate.

title_offset

Default `c(20,20)`. Distance from the top-left (default, `gravity` direction in image_annotate) corner to offset the title.

title_color

Default `black`. Font color.

title_size

Default `30`. Font size in pixels.

title_font

Default `sans`. String with font family such as "sans", "mono", "serif", "Times", "Helvetica", "Trebuchet", "Georgia", "Palatino" or "Comic Sans".

title_bar_color

Default `NULL`. If a color, this will create a colored bar under the title.

title_bar_alpha

Default `0.5`. Transparency of the title bar.

image_overlay

Default `NULL`. Either a string indicating the location of a png image to overlay over the image (transparency included), or a 4-layer RGBA array. This image will be resized to the dimension of the image if it does not match exactly.

vignette

Default `FALSE`. If `TRUE` or numeric, a camera vignetting effect will be added to the image. `1` is the darkest vignetting, while `0` is no vignetting. If vignette is a length-2 vector, the second entry will control the blurriness of the vignette effect.

instant_capture

Default `TRUE` if interactive, `FALSE` otherwise. If `FALSE`, a slight delay is added before taking the snapshot. This can help stop prevent rendering issues when running scripts.

bring_to_front

Default `FALSE`. Whether to bring the window to the front when taking the snapshot.

...

Additional parameters to pass to magick::image_annotate.

Value

Displays snapshot of current rgl plot (or saves to disk).
