This commit fixes an error whereby current the slice and tile ids would be reset to zero at the start of each geometry slice, causing the slice and tile ids set by the partitioning method to be overwritten.

Maintains contexts for: 64->6: 0n, ud, 1n, 2nh, 2nv, 3n 64->6->5: 0n, ud+1n, 2nh, 2nv, 3n 64->6->3: 0n, ud+1n+2nh, 2nv+3n Where ud = up/down, 1n = single neighbour 2nh = two horizontal neighbours 2nv = two vertical neighbours 3n = three neighbours 0n = no neighbours

When the same geom_box_log2_scale is used for all slices, it is not necessary to store them in slice headers. This commit permits signalling of the common value in the GPS.
-
This commit introduces prediction by previously coded points within the same level of detail using the predicting attribute coder. The feature is controlled using --intraLodPredictionEnabled=0|1.

This method has been replaced by an LoD decimation method.
-
This LoD generation (subsampling) method uses the Morton-based ordering of points that is used to determine prediction neighbours. Each LoD level comprises 3/4 of the points of the previous.
-
This commit introduces zero run length coding for attribute residual value along with an eq1 flag which indicates if residual value is equal to 1 based on the current residual coding specification. In zero run length coding, the number of zeros prior to each residual value is counted as zerorun, and then zerorun is encoded instead of encoding sequence of 0s

This commit permits signalling a per-slice delta QP for luma and chroma attribute components. The delta is relative to the base value derived from the APS. NB: while syntax support and derivation processes are provided, this commit does not contain any method to control the delta QP value at the encoder.
-
This commit introduces control of the quantisation step size using the familiar HEVC | AVC quantisation parameter.

This commit adds an extra contextualisation bit for occupancy coding based on there being an unoccupied adjacent child neighbour, rather than just depending upon the number of occupied neighbours.
-
David Flynn authored
This proposal reduces the number of neighbour configurations used in occupancy contextualisation from {10, 10, 10, 10, 10, 10, 7, 5} to {9, 9, 9, 9, 5, 5, 3, 2} by replacing the 64-to-10, 10-to-7, and 10-to-5 mapping tables with 64-to-9, 9-to-5, and 9-to-3 tables.

The integration of m43781 fast lifting for lossy attributes removes the need for PCCIncrementalKdTree3.

This function has never been used.

Since the implementation has no interaction with the FixedPoint class, it makes little sense to name it so.

This is part of a series attempting to remove unhelpful typedefs. The old typedefs (PCCBox3D) is retained for compatibility, but marked as deprecated.

The ply-merge tool combines point clouds from multiple ply files into a single output with an extra per-attribute frameindex property that identifies which input frame each point belongs to. The tool is also able to reverse the process and split a merged point cloud into individual frames.

This commit fixes the ability to code with neighbourAvailBoundaryLog2=0, which correctly disabled the contextualisation based on externally adjacent child neighbours, but failed to disable the atlas update.

This commit fixes an issue with the bytewise occupancy coder caused by a mismatch (swapping) of the method arguments resulting in a corrupt bitstream.
