Remarks

Why these are methods rather than inline comparisons. Nine sites in the engine spelled "is this field 3D?" as FieldType == AABB3F || FieldType == BSphere3F, which was exactly right while the f64 tiers were rejected at ConfigureSpatialGrid and became a silent misclassification the moment #914 accepted them: an AABB3D archetype would have read as 2D, collapsing every query to the grid's flat plane (SpatialGrid.FlatPlaneZ) and answering nothing for entities anywhere else on Z. That is SQ-01's silent direction, and a predicate that has to be updated in nine places when a tier lands is the mechanism that produces it.

Methods

Is3D(SpatialFieldType)

True when the field carries a Z extent — the four 3D variants, at either precision.

public static bool Is3D(this SpatialFieldType fieldType)

Parameters

fieldType SpatialFieldType

Returns

bool

IsF64(SpatialFieldType)

True when the field stores double-precision coordinates — the four *D variants.

public static bool IsF64(this SpatialFieldType fieldType)

Parameters

fieldType SpatialFieldType

Returns

bool
