   |
FBox | GetBounds () |
Returns the full bounds (including density fall-off) of the data |
   |
int | GetDimension () |
Returns the dimension of the data type, which has nothing to do with the dimension of its points |
   |
FVector | GetNormal () |
Returns the expected data normal (for surfaces) or eventual projection axis (for volumes) |
   |
FBox | Returns the bounds in which the density is always 1 | |
   |
bool | Returns true if the data has a non-trivial transform | |
   |
bool | True if this operation does not have an inverse and cannot be queried analytically/implicitly, and therefore must be collapsed to an explicit point representation. | |
   |
bool | SamplePoint
(
const FTransform& Transform, |
Sample rotation, scale and other attributes from this data at the query position. |
