Currently I am trying to port my project to Polyvox 0.2.1. And doing my voxel picking thing. As posted here http://www.volumesoffun.com/phpBB3/viewtopic.php?f=14&t=492.

But when I compile my source code, I get following errors in file "Raycast.inl"!

Code:

I really donnot know what's wrong!

this 4 files are voxel picking related. are there any bugs there? Currently I am not sure whether the Callback is on its right way!

I have just check that there are new files added to the .2.1 source named "Picking.inl" within "develop" Branch. May be it can Solve my problem!

Which version of Visual Studio are you using? The released version of PolyVox 0.2.1 should work with 2008 and 2010, but the code in develop branch is currently only tested with 2010.

Do the examples work for you? Perhaps you are not sure because of the Qt5 problems?

You should indeed look at Picking.h/inl. These provide a simpler interface where you do not have to specify a callback function. Instead you just have to provide an example of an empty voxel.

Thank you David,the picking.h/inl works now. I am using VC++2010. The problem above is really wired.

Anyway it works.

Interesting... did you get the examples to compile? When I tested it I couldn't build the A* pathfinder example due to the use of std::function. Apparently there is a known bug in VS2012 here, so I was actually planning to replace the std::function with more standard callbacks.
