Irrlicht Engine

Hey,

currently I'm trying to understand how OpenGL contexts, frame buffer objects etc. work and I'm playing around with it a little.

Now, I came up with some questions that when answered would help me a lot to understand things better - and maybe apply some stuff.

So lets say in a scenario I have ...

@mongoose7: Thank you for your effort!
Although I have to admit, I don't really understand what I have to do... do you mean to set the EMT_ONETEXTURE_BLEND as material type? Just tried it, it didn't work either...

Hmm, I'm wondering if it can really be that difficult to just get something ...

Hey, thanks for the reply!

I forgot to mention, that I tried EMT_TRANSPARENT_ALPHA_CHANNEL as well, but it didn't work either...
I tried almost all the material types that seemed to make sense to me...

Hey,

I guess I'm just missing something very basic, but I just can't get a HLSL shader to make a terrain transparent.

What I want is to be able to "hide" a terrain partially by using a pixel shader and making it partially transparent. But it seems like the alpha channel is being ignored or ...

Hi,

for the purpose of creating a lightmap generator, I'm wondering if there is a solution to the following problem:

I'm checking the ray going from the light source to the destination point for collision with other objects using getSceneNodeAndCollisionPointFromRay() .

Now some objects have ...

Hey,

right now I'm working on a custom editable terrain scene node based in the CTerrainSceneNode Irrlicht comes with.
Well, I'm having a little trouble understanding how the Mesh is actually being rendered.

I understand there is a CTerrainSceneNode::RenderBuffer, the mesh buffer that actually is ...

All the links seem to be dead... can someone post the latest version?
Thanks

Hm okay, thanks for the explanation!
I guess I just have to use a workaround then...

One more question regarding the terrains:
Why does the TerrainSceneNode ignore the transformation variables of ISceneNode and uses TerrainData.Position etc.?

Terrain->getAbsoluteTransformation thus just returns an ...

Hm, okay... but why is that? What are the technical reasons?

Hm, I don't want to be annoying - but is there a chance of that bug getting fixed?

Hey,

when creating a terrain scene node the terrain is always 16 units smaller than it is supposed to be. Is that an Irrlicht bug?

For example, if you resize the heightmap in the media directory of Irrlicht to a size of 32x32 and you run the terrain rendering example in the bin directory, after ...

How can I enable specific settings? I can only find IVideoDriver::setMaterial(const SMaterial& material), and that function takes only the material as parameter...

Hi,

is there a way of rendering the whole scene as wireframe?

If I have two cameras which render in split screen mode and I want one of them to render in wireframe mode, how do I do that?

Setting the material of every object wireframe before the second cameras rendering process and back to normal ...

In CColorAttribute, getString() is not implemented. Hence a CColorAttribute object takes the getString() function of CNumbersAttribute, which returns the color with its four components (like 255, 255, 0, 255) instead of a hexadecimal value.
I believe it should behave the same way as getStringW.

Hey blAaarg,
thank you very much for your help!

I finally got it to work!
Indeed I had to set the last parameter of beginScene().
Nevertheless, I still had to use setViewport AND setAspectRatio in order to get everything displayed the right way.

Now I got it looks somewhat like this:
cam ...
