Irrlicht Engine

In my previous post, http://irrlicht.sourceforge.net/forum/viewtopic.php?f=1&t=47978 , I was asking about bad shading that appears on sharp edges. I was using an OBJ file. This did not appear when I use meshlab or blender. Klunk then suggested me to recalculate the normals.

However, I found this ...

Yes, thank a lot! It works. I can get rid off the unwanted shading around the sharp edges.

Thanks again!

Sorry for another stupid question. I checked your suggestion and I found that recalculateNormals is a pure virtual funciton. Does it mean I have to derive IMeshManipulator class and implement my own normal recalculation routines?

Thanks.

I forgot to tell that in the area where the lines are pointing, they are very sharp angle parts. For example: parts with holes or two separated part when you try to connect them but leaving very small unnoticeable gap in between.

Correct me if I am wrong. I had an object, an OBJ file. And than I added some lights. So probably this is what you call shading. Am I right?

Hi All,

I am not sure if this is the right section to ask about this question.

I am using Irrlicht for my research to visualize my robot. As you can see in the attachment, since I am trying to render very complex mechanical structure, Irrlicht gave me broken shadowing on connections and holes. Is ...

Thanks for replying.

I do disable the vsync .

And I tried to find out more about bounding box, I checked CostumizedSecenNode example that came with Irrlicht package. It seemed that bounding box is a box that is sorounding a scene node around its origin point.

So, in my case, I have several scene ...

I tried all suggestions from CuteAlien, but nothing works.

I checked PerPixelLighting demo, it works just like the way I mentioned earlier, when I go to outer empty spaces, the FPS increased.
But it does not happen to me. I saw that there were no special variables/parameters tuned to get this kind ...

Thanks for quick reply.

@ Bl00drav3n:
I load my object using the standard way as in Hello World tutorial:


nds->bed_node = smgr->addOctreeSceneNode(smgr->getMesh( "../model/bed_structure.obj"));


Of course, I have like 10 of these objects. They have certain hierarchy, like one node is a child ...

Hi All,

Right now I am working on a simulation for my university with several OBJ files and total 1166892 poly. As expected, the FPS goes to around 33 FPS.
But what is really strange, even when I move my camera to some an empty space with nothing on it to render/display, I still have the same 33 ...
