Hi,
Several days ago I asked about depthpartition, but now I've a more complex situation that I want to figure out. It begins with depth partition but ends up with how cameras do work. I tried to combine the depth partition with the osgdistortion code. The idea was to try to put cameras above and under the depth partition node and see the effect. I got pretty much confused. First I tried to put the DPN above the distorted scene. It did not render correctly. Only the closer depth interval of the two intervals was rendered. So I tried to put the DPN above the scene and under the distortion node. Then NOTHING was rendered. I tried to change the DPN camera render order to PRE_RENDER. Again, nothing. Then when I changed it to NESTED_RENDER, all was rendered but not in the correct order. So I tried to change the RenderOrderNUM of the cameras of the DPN to "ensure" that the far intervals will be rendered first (lower RenderOrderNUM) but it did not help... So it brings up questions: 1. Why does the RenderOrderNUM didn't have effect? 2. Where is the "correct" place to put the DPN? 3. Why when the DPN was above the distortion node the closer interval was rendered, and when there is no DPN at all, the farther interval is rendered? 4. Why when the cameras of the DPN were not NESTED_RENDER nothing was rendered? 5. Would it be more correct to add Slave cameras to the scene instead of using these cameras only in the culling traverse? I guess that's it for now... Guy.
