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