Function Documentation

requireValidCloud()

template<class T >

void EBGeometry::PointCloudDetail::requireValidCloud ( const char *  a_who, const std::vector< Vec3T< T > > &  a_positions  )

inlinenoexcept

Abort with a message unless a point cloud can be indexed.

Checks, once per construction, that the number of points fits the uint32 cloud indices the structures store and report (with PointCloud::InvalidIndex left over as the "no point" sentinel), and that every coordinate is finite. Always on rather than an EBGEOMETRY_EXPECT: each would otherwise be a silently truncated cloud or a poisoned build in a Release build.

Template Parameters

T	Floating-point precision.

Parameters

[in]	a_who	Class being built, for the message.
[in]	a_positions	Point positions.
