Irrlicht Engine

Using OpenGL as driver and Irrlicht 1.5. Slowing down the framerate I can see what is happening. The frames are instead of: Original -> Orignal -> Original -> etc... I get: Blank -> Original -> Blank -> etc... Mirror Org -> Blank -> Mirror Org I tested it with Direct3d 8 and 9 driver, but then I onl...

One thing though. With this change, suddenly my texture got mirrored. Why is this? Well both the actual image _and_ a mirrored copy beneath.

[EDIT: If i don't update it (only draw it the first time, I only get the mirrored one).]

I changed the addTexture to addRenderTargetTexture, and it certainly did the trick! Thank you for the tip.

Hey. I've drawn some graphics to an ITexture, and mapped it to cube. Now I want to update the graphics to the texture, but suddenly I get like 5fps. First I thought it was the 2D library (cairo), but I isolated it down to only (ITexture*)texture->lock() and later unlocking it. Why is this slow? And ...

This is kind of off topic, but it is a general c++ programming issue. Irrlicht is one of the very few libraries I have managed to link with. I have tried to link with a lot of open source 3rd party libraries though. My consistent low success has lead me to believe that I'm missing something. Is ther...

Anybody been trying to work with other pure(r) java implementations of a 3D engine like jMonkeyEngine, Jake, jPCT...? How does that compare to irrlicht? I like that jogl is swing compatible, but on the other hand, a higher level wrapper than pure opengl would probobly result in less jni calls, givin...
