Field Documentation

alloc_lines

plus_t P_node::alloc_lines

Allocated space for lines.

Definition at line 1437 of file dig_structs.h.

Referenced by dig_free_node(), and dig_node_alloc_line().

angles

float* P_node::angles

List of angles of connected lines.

Angles for lines/boundaries are in radians between -PI and PI. Value for points or lines with identical points (degenerated) is set to -9. See dig_calc_begin_angle() and dig_calc_end_angle() for details.

lines

plus_t* P_node::lines

List of connected lines.

Line id can be positive (for lines which starts at the node) or negative (for lines which ends at the node).

n_lines

plus_t P_node::n_lines

Number of attached lines (size of lines, angle)

If 0, then is degenerate node, for snapping ???

x

double P_node::x
