XEffects - Reloaded - New Release (V 1.4)

[ent1ty]

So I noticed its not light that moves, but shadows. None knows what to do with this? Could it be a problem with my graphic card?(I have problems with my graphic card in games)

[BlindSide]

It's most likely a driver bug, does it happen in both OpenGL and D3D?

If it only happens in one of them then that's most likely the case.

[ent1ty]

It happens both in d3d9 and ogl... but it might be a problem with my graphic card
if someone could try this and tell me if he has the problem i do: http://www.edisk.sk/stahni/70733/Releas ... .34MB.html

thanks in advance

Yeah it's happening for me, can you post the source code of the entire application or a smaller working testcase so I can find the problem?

Ok the problem is very simple. You are adding a shadow to the camera scene node and this is screwing everything up.

In your loop you need to check it with:

Code: Select all

    if(node->getType() == ESNT_CAMERA)
	  continue;

Cheers

[ent1ty]

Works perfectly now, thank you very much.
And the shadows look very nice, really good work

[ent1ty]

Is there any way to destroy a ShadowLight created with EffectHandeler->addShadowLight(SShadowLight)? I thought about setting the lights color I want to destroy to black but its kind of uneffective.

Hi, Blindside.

Not looked much the SDK yet, excuse me if the feature already exist.

Is there a way to change (once created) the shadow node parameter set on a model?

Parameter I would like to change:
- Refresh interval (calculation of the shadow)
- Lightmap resolution

I would like to have multiple lights in a scene and would like to "try" to control the light setup based on the distance. Being able to change theses parameter on the shadow nodes will solve a lot of troubles, and I will surely gain a lot of performance. (Because I'm mostly lazy! )

[ent1ty]

You can change the shadowmap resultion with
effect->getShadowLight(light).setShadowMapResolution(irr:u32)

im not sure if this is what you want?
If you'r using some better IDE then it is really very easy to learn what you can do with the light once created by writing effect->getShadowLight(light). and all possibilities will pop up


How about destroying the shadowlight? is there no way?

[BlindSide]

How about destroying the shadowlight? is there no way?

Yes I think there is no way at the moment. I was going to add it in the previous release but I realised the design of XEffects didn't make it easy to retrieve and manipulate shadow lights. Instead you will have to wait until shadows are integrated in Irrlicht for easy manipulation of shadows using the famliar ILightSceneNode and SLightData interfaces.

Too bad I could save 5 fps in night and another 5 when flashlight turned off. Is there any chance of adding this soon?

[xDan]

@xDan and 3DModellerman: Most effects aren't supported on SM 2.0 cards. The most you'll get is standard shadow mapping without any filtering. If using this in an application I recommend that you have these effects optional and only enable them when the graphics card can run them. xDan if you pay for shipping I can send you my old AGP Geforce 6200 which can run all the effects but its a bit slow and old.

Thanks but that's ok I can certainly make them optional..

Hopefully in Irrlicht 1.7

[christianclavet]

Thanks for the info. Im really not in a hurry. I have a LOT of other stuff to prepare before going on with this.

I'll be happy to see new shadows types in the new releases of IRRlicht!
