◆ area2()

int area2 ( const int *  a,
const int *  b,
const int *  c 
)
inline

◆ collinear()

bool collinear ( const int *  a,
const int *  b,
const int *  c 
)
inline

◆ computeVertexHash()

int computeVertexHash ( int  x,
int  y,
int  z 
)
inline

◆ left()

bool left ( const int *  a,
const int *  b,
const int *  c 
)
inline

◆ leftOn()

bool leftOn ( const int *  a,
const int *  b,
const int *  c 
)
inline

◆ next()

int next ( int  i,
int  n 
)

◆ rcBuildPolyMesh()

bool rcBuildPolyMesh ( rcContext *  ctx,
rcContourSet &  cset,
const int  nvp,
rcPolyMesh &  mesh 
)
Note
If the mesh data is to be used to construct a Detour navigation mesh, then the upper limit must be retricted to <= DT_VERTS_PER_POLYGON.

◆ rcCopyPolyMesh()

bool rcCopyPolyMesh ( rcContext *  ctx,
const rcPolyMesh &  src,
rcPolyMesh &  dst 
)

Copies the poly mesh data from src to dst.

Parameters
[in,out]ctxThe build context to use during the operation.
[in]srcThe source mesh to copy from.
[out]dstThe resulting detail mesh. (Must be pre-allocated, must be empty mesh.)
Returns
True if the operation completed successfully.

◆ rcMergePolyMeshes()

bool rcMergePolyMeshes ( rcContext *  ctx,
rcPolyMesh **  meshes,
const int  nmeshes,
rcPolyMesh &  mesh 
)
