Why would points::appendAttribute not like a vec3R attribute?

[cgolchert]

I have some 3rd party code that I'm trying to debug.

It has ALMOST exactly the points cookbook code except it uses vec3R instead of float.

using Codec = openvdb::points::FixedPointCodec</1-byte=/false, openvdb::points::UnitRange>;
openvdb::points::TypedAttributeArray<Vec3R, Codec>::registerType();
openvdb::NamePair testAttribute = openvdb::points::TypedAttributeArray<Vec3R, Codec>::attributeType();

The above Vec3R breaks the

openvdb::points::appendAttribute(grid->tree(), "test", testAttribute );

If I switch it to float it becomes the cookbook example and works. Can anyone tell me what is wrong?

Hi Chris, most of these compression schemes are designed primarily for reducing the size of float attributes (as opposed to double attributes), so I would recommend trying with Vec3S attributes. Otherwise, it might be helpful to see the error you’re running into?

I'm not sure why they were using a Vec3R. I got it working with a nullcodec and found a few weird headers that had a typo. I'll see if their stuff works with the Vec3S and a actual codec. Thanks so much.
