Some compile errors

Hello,

Normally I would be able to solve such compile errors, but these are just missing includes files.

I tried compiling the Thermite engine (or even QtOgre) and I first got a few issues with CMake (QT4_X commands where missing, I removed those from the CMakeLists.txt...not the smartest choice). After that I tried compiling in Release mode, and I got a few missing includes.

This is the full compile log of Thermite (I know the application.h and GameLogic.h is from QtOgre):

I could probably solve the DotSceneHandler.h, but where are the ui_X.h files?

Thanks in advance,

Nevermind, after trying to reconfigure with CMake with the QT4_X commands I found out that I didn't setup QT correctly. I did that now and QT seems to generate those files at compile time.

Ok, I'm glad you fixed it. Let me know if you have any more questions or problems, but I only have limited internet access at the moment so apologies in advance if it takes me a couple of days to reply.

Well, in the OpenGL example of PolyVox you create a static mesh of the volume. But how would one handle this when they would like for example the destructable terrains as you show in Thermite? This sounds alot more complexer because the OpenGL example create mesh takes quite long to accomplish, so this can't be done every step. (or only when the volume is changed)

Running the marching cubes algorithm over the whole volume is indeed quite slow (btw, debug builds are very slow, be sure to test in release mode) and typically takes a few seconds. The trick is to break the volume into a number of regions, so that when you modify a voxel you only need to regenerate the mesh for the region which has changed.

Actually the PolyVox demo already uses regions (although as you say it doesn't currently support modification). I won't have the code in front of me for the next three weeks or so but try searching for something like 'RegionSize'. Also, if you find where the 'extract surface' function (I forget the exact name) is called you should find it is in a three level 'for' loop which iterates over the regions and generates the meshes.

Essentially, whenever you modify a voxel you need to mark it's corresponding region as having been modified. Then, later that frame or the next frame you can regenerate the mesh corresponding to that region. You can keep track of this yourself quite easily, or you can look at the VolumeChangeTracker as a utility class to handle this for you. Making the regions 1/8 the width, height, and depth of the volume is reasonable and gives 512 regions.

Does that make sense?

Hi, the best place to find information about the QtOgre framework is here: http://www.ogre3d.org/forums/viewtopic.php?f=11&t=45709.

The DotSceneHandler based on Qt can be found in the QtOgreFramework, which in turn can be found in the Ogre Addons SVN here: http://www.ogre3d.org/developers/addons

But be aware that this class isn't finished, and only handles an small amount of DotScene files. You will probably be better off using a more complete DotScene loader such as this one: http://www.ogre3d.org/wiki/index.php/New_DotScene_Loader. You might also want to ask on the Ogre furums about which one is best to use.
