◆ bezt_edge_handle_angle()

static float bezt_edge_handle_angle	(	const CurveProfilePoint *	path,
		int	i_edge
	)

static

Helper function for 'BKE_curveprofile_create_samples.' Calculates the angle between the handles on the inside of the edge starting at index i. A larger angle means the edge is more curved.

Parameters

i_edge The start index of the edge to calculate the angle for.

void BKE_curveprofile_create_samples	(	CurveProfile *	profile,

		CurveProfilePoint *	r_samples
	)

Used for sampling curves along the profile's path. Any points more than the number of user-defined points will be evenly distributed among the curved edges. Then the remainders will be distributed to the most curved edges.

Parameters

n_segments	The number of segments to sample along the path. Ideally it is higher than the number of points used to define the profile (profile->path_len).
sample_straight_edges	Whether to sample points between vector handle control points. If this is true and there are only vector edges the straight edges will still be sampled.
r_samples	Return array of points to put the sampled positions. Must have length n_segments. Fill the array with the sampled locations and if the point corresponds to a control point, its handle type.

void BKE_curveprofile_create_samples_even_spacing	(	CurveProfile *	profile,

Samples evenly spaced positions along the curve profile's table (generated from path). Fills an entire table at once for a speedup if all of the results are going to be used anyway.

Note: Requires BKE_curveprofile_init or BKE_curveprofile_update call before to fill table.; Working, but would conflict with "Sample Straight Edges" option, so this is unused for now.
