OpenGL Volumetric Lighting

Because you have to recompile your application with the new headers. Due to class changes this would otherwise lead to inconsistent pointers, which will usually crash.

Wow, thank you very much.

To Hyprid, I don't understand what is happening. Everything seems alright, but there isn't any volume lighting effect in my Program which is running with DirectX9, whether or not with realtime shadows.

Texture loaded ok!
Application running ok with newest version from source control.

Did you check the necessary steps for a volumetric light? It's described in example 8.

Hi Hybrid, I cannot see any "necessary steps" in example 8, just a notice about automatic shadow effect in top of example 8 page.

Is there any Hardware requirement for this effect?

Did you check the version in SVN (the code, not html)? This feature is only available in SVN. No hardware requirement besides a not too old version of OpenGL (in case you use OpenGL for rendering).

Thank you so much Hybrid, I am missing interface file for VolumetricLighting code. The instruction in this topic missing that interface.

I don't exactly understand what you're saying, but here's the code from example 8

Code: Select all

        //volumetric lighting
        scene::ISceneNode * n = smgr->addVolumeLightSceneNode(NULL, -1,
                                                        32, //Sub Divid U
                                                        32, //Sub Divid V
                                                        video::SColor(0, 180, 180, 180), //foot colour
                                                        video::SColor(0, 0, 0, 0) //tail colour
                                                        );

        if (n) {
                n->setScale(core::vector3df(56.0f, 56.0f, 56.0f));
                n->setPosition(core::vector3df(-120,60,40));
                video::SMaterial& mat = n->getMaterial(0);
                mat.setTexture(0, smgr->getVideoDriver()->getTexture("../../media/lightFalloff.png"));
        }

Hi, my demo with DirectX 9 has a error with Volumetric Lighting.
Please check this topic:

Hi,
Can this volumetric lighting be made to a cone shape spotlight?
I am ending up with like a laser sword light if I extend its shape...

Thanks..
