Function Documentation

bj_check_circle_segment_hit()

bj_bool bj_check_circle_segment_hit	(	struct bj_vec2	c,
		bj_real	r,
		struct bj_vec2	l0,
		struct bj_vec2	l1 )

Check if a circle intersects with a line segment.

Tests whether a circle centered at c with radius r intersects the line segment from l0 to l1.

Parameters

c	Circle center position.
r	Circle radius.
l0	Start point of the line segment.
l1	End point of the line segment.

Returns

BJ_TRUE if the circle intersects the segment, BJ_FALSE otherwise.

bj_check_segments_hit()

bj_bool bj_check_segments_hit	(	struct bj_vec2	a0,
		struct bj_vec2	a1,
		struct bj_vec2	b0,
		struct bj_vec2	b1 )

Check if two line segments intersect.

Tests whether the line segment from a0 to a1 intersects with the segment from b0 to b1 in 2D space.

Parameters

a0	Start point of first segment.
a1	End point of first segment.
b0	Start point of second segment.
b1	End point of second segment.

Returns

BJ_TRUE if the segments intersect, BJ_FALSE otherwise.
