+        @brief A special SBBRenderTechnique used in an OGRE environment.
+
+        Instead of rendering to the frame buffer this Technique renders into two render targets at the same time.
+        The firs render target will be used as it were an ordinary backbuffer.
+        The second rendertarget will be used to simulate heat shimmering (offset values will be written to it).
+        The shimmering effect will be achieved with post processing: combining the backbuffer with the first render target using the second render target as uv offset.
+        Just like the spherical billboard techniqeue, this thechnique requires a depth image taken from main camera's viewpoint.
