(
ConvexHull * out,
Geo::v128 a,
Geo::v128 b,
Geo::v128 c,
float bloat,
Geo::s32 cornerSmoothness
)

Bloat a triangle by a specified amount.

You can specify how refined you want the rounded corners to be, or 0 if you just want a single join point in the centre. The number correlates to how many segments the widest corner will have (and will scale from there). As this is a reasonably quick function, you should pass in a convex hull with the appropriate number of points allocated to it.

Returns

The number of points used, or -1 if there wasn't enough space.

Note

Passing NULL for outIS VALID

: this will return the number of points the final result will use.

Winding order is irrelevant: it is corrected internally.

bool GEO_CALL Geo::BuildPointKdTree

public: bool GEO_CALL BuildPointKdTree
(
PointSplitState & commonState
)

Construct a kd-tree of points.

The points in commonState.m_PointArray will be sorted inplace into a balanced kd-tree, and the corresponding leaf nodes and split nodes (aka internal or branch nodes) will be pushed into commonState.m_Splits and commonState.m_Leaves. The root node of the tree is always the first element in commonState.m_Splits. This call will always succeed under normal operation, but could fail internally if we run out of memory. However, because we build a balanced tree it's possible to pre-allocate an upper bound on all memory. We also assume all points are finite, but do not check this explicitly. If we do run into memory allocation issues, we return false. Otherwise this returns true.

u32 Geo::HashBig

public: u32 HashBig
(
const void * key,

This is the same as HashWord() on big-endian machines.

u32 Geo::HashLittle

public: u32 HashLittle
(
const void * key,
size_t length,
u32 initval
)

Hash a variable-length key of bytes into a 32-bit value.

Every bit of the key affects every bit of the return value. Two keys differing by one or two bits will have totally different hash values.

The best hash table sizes are powers of 2. There is no need to do mod a prime (mod is sooo slow!). If you need less than 32 bits, use a bitmask. For example, if you need only 10 bits, do h = (h & hashmask(10)); In which case, the hash table should have hashsize(10) elements.

If you are hashing n strings (u8 **)k, do it like this: for (i=0, h=0; i<n; ++i) h = HashLittle( k[i], len[i], h);

By Bob Jenkins, 2006. bob_jenkins@burtleburtle.net. You may use this code any way you wish, private, educational, or commercial. It's free.

Use for hash table lookup, or anything where one collision in 2^^32 is acceptable. Do NOT use for cryptographic purposes.

Parameters

	key	The key (the unaligned variable-length array of bytes)
	length	The length of the key, counting by bytes
	initval	Can be any 4-byte value

Returns

Returns a 32-bit value.

u32 Geo::HashWord

public: u32 HashWord
(
const u32 * k,
size_t length,
u32 initval
)

Produce a hash from a string of Geo::u32 This works on all machines.

To be useful, it requires

That the key be an array of u32's, and
That all your machines have the same endianness, and
That the length be the number of u32's in the key The function HashWord() is identical to HashLittle() on little-endian machines, and identical to HashBig() on big-endian machines, except that the length has to be measured in u32s rather than in bytes. HashLittle() is more complicated than HashWord() only because HashLittle() has to dance around fitting the key bytes into registers.
