Renderer functions that combine individual frame images into a final animation file. These are factory functions that return the actual rendering function.
Usage
gifski_renderer_3d(file = NULL, loop = TRUE)
av_renderer_3d(file = NULL, vfilter = "null", codec = NULL)
file_renderer_3d(dir = ".", prefix = "ggcube_frame", overwrite = FALSE)Arguments
- file
Output file path. If
NULL, a temporary file is used.- loop
Logical. Should the GIF loop? Default is
TRUE.- vfilter
A video filter string for ffmpeg (passed to av).
- codec
Video codec name. Default lets av choose.
- dir
Directory to copy frame files into.
- prefix
Filename prefix for copied frame files.
- overwrite
Logical. Overwrite existing files? Default is
FALSE.
Value
A function with signature function(frames, fps, width, height)
that produces the animation output.
Examples
if (FALSE) { # \dontrun{
p <- ggplot() +
geom_function_3d(
fun = function(x, y) sin(x) * cos(y),
xlim = c(-pi, pi), ylim = c(-pi, pi),
fill = "steelblue", color = "steelblue") +
coord_3d()
# GIF output (default)
animate_3d(p, yaw = c(0, 360), renderer = gifski_renderer_3d())
# Video output
animate_3d(p, yaw = c(0, 360), renderer = av_renderer_3d())
# Keep individual frame files
animate_3d(p, yaw = c(0, 360),
renderer = file_renderer_3d(dir = "my_frames"))
} # }
