【问题描述】:
我正在使用
BOOST_GEOMETRY_REGISTER_POINT_3D(glm::vec3, float, boost::geometry::cs::cartesian, x, y, z);
RTree 定义为:
using IndexedPoint = std::pair<glm::vec3, uint32_t>;
using RTree = boost::geometry::index::rtree<IndexedPoint, boost::geometry::index::rstar<8>>;
当我尝试使用它运行最近邻查询时,它无法编译:
auto it = rtree.qbegin(boost::geometry::index::nearest(glm::vec3(), 3))
错误是:
error C2664: 'int boost::mpl::assertion_failed<false>(boost::mpl::assert<false>::type)': cannot convert argument 1 from 'boost::mpl::failed ************(__cdecl boost::geometry::strategy::distance::services::default_strategy<boost::geometry::point_tag,boost::geometry::box_tag,glm::vec<3,float,0>,boost::geometry::model::point<float,3,boost::geometry::cs::cartesian>,boost::geometry::cartesian_tag,boost::geometry::cartesian_tag,void>::NOT_IMPLEMENTED_FOR_THIS_POINT_TYPE_COMBINATION::* ***********)(boost::mpl::assert_::types<Point1,Point2,CsTag1,CsTag2>)' to 'boost::mpl::assert<false>::type'
with
[
Point1=glm::vec<3,float,0>,
Point2=boost::geometry::model::point<float,3,boost::geometry::cs::cartesian>,
CsTag1=boost::geometry::cartesian_tag,
CsTag2=boost::geometry::cartesian_tag
]
comparable_distance_result 似乎缺少 vec3 与 boost::geometry::model::point 和 boost::geometry::model::box 的特化。我曾尝试手动添加它们,但无法使其工作。如何添加所需的距离类型特化?
请注意,我可以很好地使用相同的设置进行空间查询,所以它看起来基本上是合理的。
