GeomTrimesh: A Custom ggplot2 Geom for Triangular Meshes

This function defines a custom ggplot2 Geom, GeomTrimesh, for rendering triangular meshes.

Usage

GeomTrimesh

Format

A ggproto object

Details

- required_aes: The required aesthetics for this geometry are "x", "y", "xend", and "yend". - default_aes: The default aesthetics for this geometry include shape = 19, linetype = 1, linewidth = 0.5, size = 0.5, alpha = NA, and colour = "black". - draw_key: The function describing how to draw the key glyph is ggplot2::draw_key_point. - draw_panel: The function describing how to draw the panel takes data, panel_scales, and coord. It creates a tibble of vertices and a tibble of trimesh. The final plot is constructed using ggplot2::GeomPoint$draw_panel for vertices and ggplot2::GeomSegment$draw_panel for trimesh.

Examples

if (FALSE) {
  # Example usage in a ggplot
  ggplot(data = my_data, aes(x = x, y = y, xend = xend, yend = yend)) +
    geom_trimesh()
}
