line_node Function

private function line_node(xyz, rgba, width, segments) result(node)

A line node through points xyz(3, n): a strip, or separate segments (points 1-2, 3-4, ...).

Arguments

Type IntentOptional Attributes Name
real(kind=wp), intent(in) :: xyz(:,:)

(3, n) points
real(kind=wp), intent(in) :: rgba(4)

color [r, g, b, a] (0 to 1)
real(kind=wp), intent(in) :: width

line width (window units)
logical, intent(in) :: segments

separate segments (else a strip)

Return Value type(c_ptr)
