Irrlicht Engine

Got it to work now finally. After desparating awhile I tried installing TDM-GCC and recompiling the Irrlicht.dll. Apparently I was just too stupid to set up MinGW w64 on my own.

Yesterday I installed MinGW w64. I was able to create a new irrlicht.dll and can now make 64 bit applications, but the BMP-Loader doesn't work anymore. In IrrCompileConfig.h "#define _IRR_COMPILE_WITH_BMP_LOADER_" is not commented out, so the new dll should include the CImageLoaderBMP.cpp. What's ...

It's the culling. With Meshnode->setAutomaticCulling(EAC_OFF) you could disable this. But the clean solution is recalculating the boundinboxes

I accept only clean solutions, of course. :wink:

In the original code I work with
TempBuff->BoundingBox.addInternalPoint(...);
(Obviously I deleted a ...

It's neither a problem with backface culling nor with the near clipping plane. The whole mesh disappears instantly, this can also happen at greater distances, the coordinates in the code are just the only ones that I know exactly.

When looking at a mesh from certain positions and at certain angles it dissappears. Does anybody know why this happens? Here's a sample code with a square, that disappears when turning right (or setting the camera target to (4, 0, 1)):

#include <irrlicht.h>

using namespace irr;
using namespace ...
