// now when computing convex hulls, it is no longer a blocking operation. All callback messages are still returned
// in the application's thread so you don't need to worry about mutex locks or anything in that case.
// To tell if the operation is complete, the application should call 'IsReady'. This will return true if
// the last approximation operation is complete and will dispatch any pending messages.
// If you call 'Compute' while a previous operation was still running, it will automatically cancel the last request
// and begin a new one. To cancel a currently running approximation just call 'Cancel'.

/**
Describes the connectivity between support chunks via bonds.
Vertices in the support graph are termed "nodes," and represent particular chunks (NvBlastChunk) in an NvBlastAsset.
The indexing for nodes is not the same as that for chunks. Only some chunks are represented by nodes in the graph,
and these chunks are called "support chunks."
Adjacent node indices and adjacent bond indices are stored for each node, and therefore each bond is represented twice in this graph,
going from node[i] -> node[j] and from node[j] -> node[i]. Therefore the size of the getAdjacentNodeIndices() and getAdjacentBondIndices()
arrays are twice the number of bonds stored in the corresponding NvBlastAsset.
The graph is used as follows. Given a SupportGraph "graph" and node index i, (0 <= i < graph.nodeCount), one may find all
adjacent bonds and nodes using:
const uint32_t* adjacencyPartition = graph.getAdjacencyPartition();
const uint32_t* adjacentNodeIndices = graph.getAdjacentNodeIndices();
const uint32_t* adjacentBondIndices = graph.getAdjacentBondIndices();
// adj is the lookup value in adjacentNodeIndices and graph.getAdjacentBondIndices()
for (uint32_t adj = adjacencyPartition[i]; adj < adjacencyPartition[i+1]; ++adj)
{
// An adjacent node:
uint32_t adjacentNodeIndex = adjacentNodeIndices[adj];
// The corresponding bond (that connects node index i with node indexed adjacentNodeIndex:
uint32_t adjacentBondIndex = adjacentBondIndices[adj];
}
For a graph node with index i, the corresponding asset chunk index is found using graph.getChunkIndices()[i]. The reverse mapping
(obtaining a graph node index from an asset chunk index) can be done using the
NvBlastAssetGetChunkToGraphNodeMap(asset, logFn);
function. See the documentation for its use. The returned "node index" for a non-support chunk is the invalid value 0xFFFFFFFF.

/**
* BondMatrix
*
* Given a BondMatrix B, when (B^T)*B is applied to a vector of bond impulses, the result
* is a vector of the differences between the the resulting accelerations of the nodes
* joined by each bond.
*
* This is done in block form, so a vector is composed of vector elements. Each element
* is a 6-dimensional vector, composed of a linear part followed by an angular part.
* Matrix blocks are likewise 6x6.
*
* This matrix is composed of two sparse matrices:
* An M x M block diagonal matrix I, where the i^th diagonal block is the 6x6 matrix:
*
* / I_i 0 \
* I_ii = | |
* \ 0 m_i /
*
* Except for possibly I_i, each "element" in I_ii is a multiple of the 3x3 unit matrix. I_i is a
* 3x3 symmetric inertia tensor. See the definition of Inertia<TensorType> for its representation.
*
* The second component is the coupling matrix C, see documentation for Coupling.
*
* The matrix represented by this object is (I^-1/2)*C, an M x N matrix.
*
* NOTE: I and C are _not_ stored as described above, for efficiency.

* Conjugate Gradient Normal Equation Residual (CGNR) solver for systems of M equations and N unknowns.
*
* Based on Matrix Computations (4th ed.) by Golub and Van Loan, section 11.3.9.
*
* Solves A*x = b.
*
* Template arguments:
* Elem: the type of element used in the vectors x and b, and (implicitly) in the matrix A.
*
* ElemOps: a class which defines various functions on Elem type and vectors of Elem type.
*
* Mat: the explicit type used to represent the matrix, allowing e.g. for sparse representations.
*
* MatOps: a class which defines the functions rmul and lmul, which multiply a matrix of type Mat
* by an Elem-typed vector on the right and left, respectively. The function signatures must be:
*
* void rmul(Elem* y, const Mat& A, const Elem* x, uint32_t M, uint32_t N); // y = A*x
* void lmul(Elem* y, const Elem* x, const Mat& A, uint32_t M, uint32_t N); // y = x*A
*
* Scalar: set to float by default. May be used to keep all operations in a particular representation, e.g. SIMD registers.
*
* \param[out] x User-supplied Elem vector of length N, filled with the solution upon exit (if successful).
* \param[in] A System M x N matrix of type Mat.
* \param[in] b Right hand side of equation to be solved, an Elem vector of length M.
* \param[in] M The number of rows in A and elements in b.
* \param[in] N The number of columns in A and elements in x.
* \param[in] cache Cache memory provided by the user, must be at least required_cache_size(M, N) bytes, and sizeof(Elem)-byte aligned.
* \param[out] error_ptr If not null, returns the square magnitude error calculated from residual.
* \param[in] tol (Optional) relative convergence threshold for |(A^T)*(A*x-b)|/|b|. Default value is 10^-6.
* \param[in] max_it (Optional) the maximum number of internal iterations. If set to 0, the maximum is N. Default value is 0.
* \param[in] warmth (Optional) valid values are 0, 1, and 2. 0 => cold, clears the x vector and ignores the cache.
* 1 => warm, uses the x vector as a starting solution, but still ignores the cache. 2 => hot, uses the x
* vector as a starting solution, and the cache must be valid. Default value is 0.
* N.B. if warmth == 2, then this function must have been called previously, and the equation values
* (x, A, b, M, and N) as well as the cache must not have been changed since the last call.
*
* return the number of iterations taken to converge, if it converges. Otherwise, returns minus the number of iterations before exiting.
