Samples the geometry’s surface at the UV texture coordinate, and returns a transform suitable for constraining an object to the surface of the geometry.
入力 ¶
geo:
Geometry
The geometry whose surface to constrain a transform onto.
uvname:
String
The name of the point or vertex attribute corresponding to the UV texture map.
uv:
Vector2
The UV texture coordinate of the position on the geometry at which to create the constraint.
urange:
Vector2
The range of the UV map in the u direction.
vrange:
Vector2
The range of the UV map in the v direction.
wrapu:
Bool
If set to True, u texture coordinates that exceed the urange of the UV map are wrapped back onto the valid range such that the UV map is repeated in the u direction.
wrapv:
Bool
If set to True, v texture coordinates that exceed the vrange of the UV map are wrapped back onto the valid range such that UV map is repeated in the v direction.
出力 ¶
xform:
Matrix4
The transform on the surface of the input geometry at the uv texture coordinate. The transform is oriented such that its y-axis is aligned to the interpolated normal of the primitive’s points.
primidx:
Int
The primitive number of the primitive containing the uv texture coordinate.
primuv:
Vector2
The primitive’s intrinsic UV position at the input uv texture coordinate.
