why shading in irrlicht is giving better result with 3ds

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...

Re: poor shadow on complex structure

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

Thanks again!

Re: poor shadow on complex structure

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.

Re: poor shadow on complex structure

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.

Re: poor shadow on complex structure

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?

poor shadow on complex structure

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 th...

Re: Low FPS even when nothing is renderd on screen

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 nod...

Re: Low FPS even when nothing is renderd on screen

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 o...

Re: Low FPS even when nothing is renderd on screen

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 ...

Low FPS even when nothing is renderd on screen

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 FPS...
