Abstract: A device for decoding encoded dynamic mesh data determines a set of quantized integer coefficient values for displacement vectors of the encoded dynamic mesh data; determines a quantization parameter based on one or more syntax elements included in a displacement sub-bitstream of the encoded dynamic mesh data; inverse quantizes, based on the quantization parameter, the set of quantized integer coefficient values to determine a set of fixed-point dequantized coefficient values; determines a set of fixed-point transformed coefficient values based on the set of fixed-point dequantized coefficient values; converts the set of fixed-point transformed coefficient values to a set of floating-point transformed coefficient values; inverse transforms the set of floating-point transformed coefficient values to determine a set of reconstructed displacement vectors; and determines a reconstructed deformed mesh based on the set of reconstructed displacement vectors.
