struct rt_bot_internal * rt_bot_gc	(	const struct rt_bot_internal *	bot,
		const int *	faces,

	)

extern

Build a compact BOT from replacement faces whose vertex indices reference the source BOT. face_sources maps every replacement face to its original source face, allowing thickness, face mode, normals, and texture UVs to be preserved. Replacement triangles must retain the corner ordering of their source faces; face_sources identifies faces but does not describe a separate corner permutation. The caller owns the returned BOT.

Returns NULL for malformed input or an invalid vertex or face reference.

◆ rt_bot_subset()

struct rt_bot_internal * rt_bot_subset	(	const struct rt_bot_internal *	bot,
		const int *	face_indices,
		size_t	face_count
	)

extern

Build a compact BOT from selected input faces. face_indices identifies the original faces, in output order, so all per-face and per-corner data can be preserved and remapped along with the referenced vertices. This is the convenience form of rt_bot_gc for unchanged source faces. The caller owns the returned BOT.

Returns NULL for malformed input or an invalid face reference.

◆ rt_bot_split()

struct rt_bot_list * rt_bot_split ( struct rt_bot_internal * bot )

extern

Split a BOT into edge-connected triangle components. A connected BOT returns an allocated empty list. On success with multiple components, each list entry owns a compact BOT preserving all source face-indexed data. Returns NULL on malformed input or another processing failure.
