Hello everyone,
i added the line
Code:
SimpleVolume<uint8_t> volData(PolyVox::Region(Vector3DInt32(0,0,0), Vector3DInt32(63, 63, 63)));
to my code and this error popped up when i try to run it

It looks like you haven't linked against the PolyVox.lib (I think that's what it is called) in your linker settings?

However, it also looks like you are using the last stable release. If you have Visual Studio 2013 or newer then I'd recommend using the 'develop' version of PolyVox from Git. This version is header-only, so you don't need to configure the linker.

Thank you for your reply . I found the developer version gonna give it a try

edit: how would i include the developer one into the project

edit: i just included the project into my one but im getting weird error
Code:
'PolyVox::PagedVolume<int>::PagedVolume(const PolyVox::PagedVolume<int> &)': cannot convert argument 1 from 'PolyVox::Region' to 'PolyVox::PagedVolume<int>::Pager *'


The line of code causing it is
Code:
PagedVolume<int> volume(PolyVox::Region(Vector3DInt32(0, 0, 0), Vector3DInt32(63, 127, 255)));

The programming interface has changed between the last stable release and the develop version. You'll need to look at the examples to see how to use the latest API as the documentation is often not up to date.

In the latest version the PagedVolume does not have a defined size, and needs to be given an instance of 'Pager' to get the data from. For example, in PagingExample:

Code:
PerlinNoisePager* pager = new PerlinNoisePager();
PagedVolume<MaterialDensityPair44> volData(pager, 8 * 1024 * 1024, 64);


However, I recommend you don't work with paging until you are quite experienced with PolyVox. It's much better to start with the RawVolume and the BasicExample until you have got volumes rendering, update and interaction working, etc.
