Selecting O3DGC Encoding Parameters

Attribute type	Quantization	Prediction mode
POSITION	Excellent quality: 13 Good quality: 12 Aggressive compression: 10	O3DGC_SC3DMC_PARALLELOGRAM_PREDICTION
TEXCOORD	10 (for 1024x1024) texture images 9 (for 512x512) texture images 8 (for 256x256) texture images N (for 2^Nx2^N) texture images	O3DGC_SC3DMC_PARALLELOGRAM_PREDICTION
NORMAL	Excellent quality: 10 Good quality: 8 Aggressive compression: 6	O3DGC_SC3DMC_SURF_NORMALS_PREDICTION if the normals magnitudes are not relevant O3DGC_SC3DMC_PARALLELOGRAM_PREDICTION to preserve the normals magnitudes
COLOR	Excellent quality: 10 Good quality: 8 Aggressive compression: 6	O3DGC_SC3DMC_DIFFERENTIAL_PREDICTION
WEIGHT	No idea yet. I need to test with real data. I would say between 8-12	O3DGC_SC3DMC_PARALLELOGRAM_PREDICTION
JOINT_ID	No quantization	O3DGC_SC3DMC_DIFFERENTIAL_PREDICTION

Computational complexity of prediction modes:

·         O3DGC_SC3DMC_PARALLELOGRAM_PREDICTION (+++)

·         O3DGC_SC3DMC_SURF_NORMALS_PREDICTION (+++)

·         O3DGC_SC3DMC_DIFFERENTIAL_PREDICTION (++)

·         O3DGC_SC3DMC_NO_PREDICTION (+)
