Member Function Documentation

static GU_PrimPolySoup* GU_PrimPolySoup::build ( GA_Detail detail)
static

Builds an empty polygon soup (i.e. contains no vertices or polygons)

static GA_Offset GU_PrimPolySoup::build ( GA_Detail detail,
const UT_Vector3 points,
const GA_Size  npoints,
const GEO_PolyCounts polygonsizelist,
const int polygonpointnumbers,
const bool  sharedvertices = true 
)
static

Builds npoints new points with the specified positions, and then creates a polygon soup that uses those points, as dictated by polygonsizelist and polygonpointnumbers, in parallel. polygonpointnumbers lists the numbers of the points used by each polygon, relative to the first point created by this method. The offset of the polysoup is returned.

If sharedvertices is false, there will be polygonsizelist.getNumVertices() vertices, and they won't be shared by any polygons in the polygon soup. If sharedvertices is true, there will be npoints vertices, and each will be shared by all polygons using the corresponding point.

NOTE: If sharedvertices is true, it's necessary for the polysoup to use all points created. If sharedvertices is false, this limitation is lifted, although doing so probably isn't useful.

static GA_Offset GU_PrimPolySoup::build ( GA_Detail detail,

Builds a polygon soup using the specified range of point offsets, as dictated by polygonsizelist and polygonpointnumbers, in parallel. polygonpointnumbers lists the offsets of the points used by each polygon MINUS startpt, i.e. they are offsets relative to startpt, not indices relative to startpt. The offset of the polysoup is returned. All polygonpointnumbers must be between 0 (inclusive) and npoints (exclusive).

If sharedvertices is false, there will be polygonsizelist.getNumVertices() vertices, and they won't be shared by any polygons in the polygon soup. If sharedvertices is true, there will be npoints vertices, and each will be shared by all polygons using the corresponding point.

NOTE: If sharedvertices is true, no primitives can be using the points in the specified range already, and polygons in the polygon soup being created should use all of them, because the vertices will be wired as the only vertices for their corresponding points. If sharedvertices is false, these limitations are lifted, allowing multiple primitives to use the same points, and allowing the polysoup being created to use a subset of the points in the range.
