Utility functions for creating common vertex patterns

Functions

create_line

Create vertices for a line from start to end point

create_line_plot

Create vertices for a parametric line plot (1px line segments)

create_line_plot_dashed

Create dashed/dotted line vertices by selectively including segments. Approximation: pattern is applied per original segment index.

create_point_cloud

Create vertices for a point cloud

create_scatter_plot

Create vertices for a scatter plot

create_thick_polyline

Create thick polyline as triangles (used when line width > 1)

create_thick_polyline_dashed

Create dashed/dotted thick polyline by skipping segments in the extruder.

create_thick_polyline_round_caps

Round caps variant: square caps plus approximated semicircle fan at ends

create_thick_polyline_square_caps

Square caps variant: extend endpoints by half width

create_thick_polyline_with_join

Thick polyline with join style

create_triangle

Create vertices for a triangle

extrude_polyline

CPU polyline extrusion for thick lines (butt caps, miter joins simplified) Input: contiguous points. Output: triangle list vertices.

extrude_polyline_with_join

Extrude polyline with join styles at internal vertices.
