RLE won't compile for me
it needs an
Code:
#include <limits>

in
Code:
library/PolyVoxCore/include/PolyVoxImpl/Block.h

after that the examples work fine

you should write to the upgrade notes that all calls to tidyUpMemory() need to be removed since it doesn't exist anymore

and while we're at it, Filters.inl doesn't need the #include "MaterialDensityPair.h" and the occurrance of MaterialDensityPair44 needs to be replaced by VoxelType (not related to RLE)

moving my project from PolyVox-trunk to RLE worked without any mentionable troubles

Thanks, I'm not going to get any development done this week but I'll make a note to fix those things before doing the merge into the trunk.

I don't think anyone here will complain if it takes time... You have done great things for us, for greater things we'll just need patience ;)

I had some odd things happening for small block side lengths :D took me a while to figure it out, I don't fill my whole volume, usually that meant it's "empty" filled with VoxelType()...
but basically I was getting the data from other blocks...

I believe the Block::initialise function needs this:

Code:
      uint32_t uNoOfVoxels = m_uSideLength * m_uSideLength * m_uSideLength;
      RunlengthEntry<uint16_t> entry;
      entry.length = uNoOfVoxels;
      entry.value = VoxelType();
      m_vecCompressedData.push_back(entry);

at least it works for Material8, I'm not sure about other materials and how they should behave

Ah, thanks. Actually I have seen there is a bug somewhere (there has been a problem with the extracted meshes using the new Volume) but I hadn't tracked it down yet. Hopefully your change will fix it :-)
