void setpackedtransform(int input, int primnum, matrix transform)
Sets the transform of a packed primitive. This modifies the P
attribute of
the primitive’s point as well as its intrinsic transform
.
Warning
This function replaces only the P
(position) attribute and the transform
intrinsic attribute. It ignores various details that the packedfulltransform
intrinsic attribute includes:
-
The packed primitive’s
pivot
intrinsic attribute. -
Instancing attributes such as
orient
(when thepointinstancetransform
intrinsic attribute is on, as with crowd agents). -
The
packedlocaltransform
intrinsic attribute (Alembic primitives).
So this function will not apply the expected transform in several different cases.
The getpackedtransform function has the same issues since it returns a transform only based on P
and transform
.
Examples ¶
// matrix to transform by matrix tf = ident(); rotate(tf, radians(45), {0,1,0}); translate(tf, {0,1,0}); matrix transform = getpackedtransform(0, @primnum); setpackedtransform(0, @primnum, transform * tf);
