(some introduction here). +Volume wrap modes +----------------- +This release has seen a overhaul of the way PolyVox handles voxel positions which are outside of the volume. It used to be the case that you could specify a border value which would be returned whenever an out-of-volume access was performed, but this was not flexible enough for all use cases. You can now choose between different wrapping modes (border, clamp, etc) and apply them to both the volume itself or to samplers. If you have multiple samplers pointing at the same volume then you can choose to have different wrap modes for each of them. + +Within the Volume class the getVoxelAt() and setBorderValue() functions have been deprecated. You should now call getVoxel() (which does not perform range checking and will crash when out of range) or getVoxelWithWrapping() (which does perform bounds checks and implements the required wrapping). When you call getVoxelWithWrapping() you are able to specify the required wrap mode for that particular call. For a Sampler you can set the wrap mode once with setWrapMode() and it will persist until you set it again. + +Various algorithms have also been updated to allow wrap modes to be specified when executing them. + Region class ------------ The Region class has been tidied up and enhanced with new functionality. It now contains functions for growing and shrinking regions, as well as 'accumulate()' functions which ensure the Region contains a given point. The concept of an invalid region has also been introduced - this is one whose lower corner is greater than it's upper corner. @@ -14,6 +22,8 @@ Deprecated functionality ------------------------ Vector::operator<() has been deprecated.
