SYS_FORCE_INLINE GEO_PrimPoly::GEO_PrimPoly ( GA_Detail gdp,
GA_Offset  offset,
const GA_OffsetListRef vertex_list 
)
inline

This constructor is for making a representation of a polygon on the stack, so that you can call GU_PrimPoly functions on the polygon without needing the detail to allocate one.

static

Builds a GEO_PrimPoly with nvertices vertices, and optionally adds a point to the detail for each vertex.

Examples:
SIM/SNOW_Solver.C, SOP/SOP_DualStar.C, and tetprim/GEO_PrimTetra.C.
static GA_Offset GEO_PrimPoly::buildBlock ( GA_Detail detail,
const UT_Vector3 points,
const GA_Size  npoints,
const GEO_PolyCounts polygonsizelist,
const int polygonpointnumbers,
const bool  closed = true 
)
static

Builds npoints new points with the specified positions, and then creates polygons that use 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 first polygon is returned, and the rest are at consecutive offsets. All polygonpointnumbers must be between 0 (inclusive) and npoints (exclusive).

NOTE: It's not strictly necessary that the polygons being created use all of the points created.

Examples:
SOP/SOP_BrushHairLen.C.

const GA_Offset  startpt,

const GEO_PolyCounts polygonsizelist,
const int polygonpointnumbers,
const bool  closed = true 
)
inlinestatic

Builds polygons 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 first polygon is returned, and the rest are at consecutive offsets. All polygonpointnumbers must be between 0 (inclusive) and npoints (exclusive).

NOTE: Existing primitives are allowed to be using the points in the specified range already, and the polygons being created do not need to use all of the points in the range. However, these cases may impact performance.

) const
finalvirtual

Finds the weightings of the vertices that will compute an interior point given the u,v,w coordinates. The offsets are into the gdp's vertex list, not indices into this primitive's vertex list. Weights are normalized. Note this cannot be used to recover the Position as it often has special case logic (as in spheres, or rational splines), in those cases use evaluateInteriorPoint(UT_Vector4 &pos, ...) It has the advantage over the other evaluateInteriorPoints in that it allows you to avoid creating any temporary vertices. Behaviour for non-sublcassed types is to return the 0th vertex.

void GEO_PrimPoly::flipEdge ( GEO_PrimPoly that,

Flips a shared edge of two triangles | j+2 j+2 i+1 | / \ /|\ | / \ / | \ | / that\ / t|t \ | j----—j+1 flips to j h|h i | i+1\ this/i \ a|i / | \ / |s/ | \ / |/ | i+2 j+1 i+2 |

i and j are indices into this and that, respectively, and are on opposite ends of the common edge, which is (i, i+1) in this and (j, j+1) in the opposite direction in that. The vertex i+1 in this is moved to where j+2 is in that. The vertex j+1 in that is moved to where i+2 is in this. NOTE: Vertex attributes will be copied from j+2 onto i+1, and from i+2 onto j+1. NOTE: The two triangles must be in the same detail.

virtual void GEO_PrimPoly::getAdjacentBoundaryVertices ( GA_Offset  vtx,
GA_Offset prev_vtx,
GA_Offset next_vtx 
) const
virtual

Return the next and previous vertex on the "boundary" of the primitive (as understood by the primitive) relative to a given vertex. These are needed to maintain half-edge topology attributes. They must be implemented for primitives that realize a notion of a boundary composed of one or more closed cycles of vertices if we want to be able to use hedges to quickly move from such a primitive to another sharing an edge with it. A GA_INVALID_OFFSET for prev_vtx or next_vtx means that either the primitive doesn't care about hedges, the input vertex is not a boundary vertex in the primitive (or not a vertex at all), or vtx is at an end of a boundary (e.g. open polys).
