+idea for incorporation of dynamic objects:
+
+store object id with render target
+for each object we know the trafo
+when doing the back projection =>
+as usual:
+transform current pixel back to world space
+find pixel from last frame using the inverse model view trafo
+
+now apply the transformation from the current frame on the pixel =>
+do the equality comparison
