V-DMC DISPLACEMENT VECTOR QUANTIZATION - A simplified explanation of the abstract
This abstract first appeared for US patent application 18630686 titled 'V-DMC DISPLACEMENT VECTOR QUANTIZATION
The abstract describes a device for decoding encoded mesh data, which involves determining a base mesh, a set of coefficients, a quantization parameter value, and a bit depth offset value. The device then calculates an inverse scaling factor based on these values, performs inverse scaling on the coefficients to obtain de-quantized coefficients, determines a displacement vector from these coefficients, deforms the base mesh using the displacement vector to generate a decoded mesh, and outputs the decoded mesh.
