Hi! I am trying to use SEQUENTIAL_ENCODING, but the sequential encoding does not preserve order for my case. I add `encoder.SetEncodingMethod(draco::MESH_SEQUENTIAL_ENCODING);` to my encoder. Below is the entire code for...

C++ API configs for lossless compression

1

Reading previous issues here, I found that the key config to achieve lossless compression is to set quantization to 0. So I use the following c++ code: ` encoder.SetAttributeQuantization(draco::GeometryAttribute::POSITION, 0);...

Standard MIME type for a Draco File?

Hi, I was wondering what the right way to designate a file as draco compressed on cloud storage. Would that be `Content-Encoding: draco` with `Content-Type: model/mesh` or would it be...

When I close prediction, func EncodeValues in SequentialIntegerAttributeEncoder will go into func ConvertSignedIntsToSymbols. Then ConvertSignedIntsToSymbols will turn uint16 value like 63990 to 127980. Then the uint16 attr will be encoded...
