Looks like the sum of all your lighting is already beyond full lighting. So basically in first step you have to get back to a situation where it's not full bright and then slowly turn the lights up. For example start with only 1 light - either dynamic or ambient and check how it's there. Reasons it...

And how do you make the shadows?

When I switch off all the lights everything is dark.
I make the shadows by adding a scenenode:

Code: Select all

((scene::IAnimatedMeshSceneNode*)n)->addShadowVolumeSceneNode();

The first thing: Which video driver do you use? It seems to me that the software driver as well as the burningsvideo driver seems not to support direct lighting. The second thing is a little bit tricky and it took me some time to understand this effect: With the coordinates of your light source (-1...

Diffuse illumination means that light comes from all space directions on your mesh object. So the brightness of a mesh is completely independent of normal directions. This is exactly the situation you show in your first image, so your diffuse illumination works pretty well. To get a brightness that...

yes, of course. It shows shadow. Any suggestion?

I am using 1.7.2. I load a 3ds mesh to the scene and add a light (see below). It seems that the diffuse lighting does not work. https://preview.ibb.co/eaXznn/nodiffuse.png I want get the following effect which I got in the rhinoceros software: https://preview.ibb.co/eGON7n/diffuse.png I tried these ...

sorry, guys. I am not tending to bother you. But it is really difficult for a 3d beginners to precisely manipulate irrlicht. It will take you just a minute but few hours of me to solve a problem. I just want to integrate irrlicht into my spatial analysis framework MicroCity.

I found there is a type of light scenenode which can be used as a dynamic point light. But I want add a parallel light that is emitted from infinity. How can I do that?

That's wrong. You need to call it between
Code: Select all
driver->beginScene()
and
Code: Select all
driver->endScene()

I got it, thanks.

how/when do you call it ??? it works for me this way: SMaterial m; m.Lighting = false; while(device->run()){ driver->beginScene(true, true, video::SColor(0,0,0,0)); smgr->drawAll(); guienv->drawAll(); driver->setMaterial(m); driver->setTransform(video::ETS_WORLD, core::matrix4()); driver->draw3DLin...

Is the line drawn wrong, or is it not drawn?

means not drawn, can not be seen, invisible

I am using 1.5. This issue made me crazy. I tested it in the helloword example. It doesn't work. see below: smgr->addCameraSceneNode(0, vector3df(0,30,-40), vector3df(0,5,0)); SMaterial m; m.Lighting = false; driver->setMaterial(m); driver->setTransform(video::ETS_WORLD, core::matrix4()); driver->dr...

I just create a camera can simulate the MAYA camera. Hope these code can help someone that have the same confusion like me. class MyEventReceiver : public IEventReceiver { public: // This is the one method that we have to implement virtual bool OnEvent(const SEvent& event) { if (event.EventType ...

I embeded a irrlicht window in wxWidgets. It worked fine for most time. But sometime when I use mouse control the camera in irrlicht window, the mouse seems trapped by irrlicht window. The interface outside the irrlicht window does not respond on mouse click. Such as close, minimize, etc. At that ti...
