Irrlicht Engine

Hello, my fellow Irrlichters! Czestmyr is back and he brought a few presents for you :wink:. I hope, you'll find them useful.

Some of you may remember my procedural fire scene node. Well I've done something similar now. It's called Procedural Texture Manager and you may create and manage procedural ...

I dont'ŧ think that skyboxes are so bad. And they definitely don't have to look 'cubeish'. If you render the skybox textures as planar projections of a 3D scene on the walls of the cube, you end up with 6 textures that are distorted on the edges, due to the projection. But when applied to the skybox ...

Rammstein is also one of my favorite groups, but does any of you know/listen to Einstürzende Neubauten? I've discovered them recently and they rule

I want an avatar too

Ooops! Language barrier caused some trouble here! Thanks for correction, but still the principle remains the same, whatever this technique is called.

I think I know where the problem is - the texture is not grayscale, but ordinary 24-bit, but if you have only grays in it, the colors fade out evenly (except for the fade-out color, which stays longer)

Spintz: Post a pic of your results and a piece of your code. I hope I'll be able to help.

I'm accessing the texture data in my new fire scene node, you can have a look at it, but basicaly you just have to do this:


u8* pixels = (u8*) texture->lock();
for (u32 i = 0; i < pixelNum; i++){
pixels[i * 4] .. //do whatever with the blue component
pixels[i * 4 + 1] .. //green component ...

Maybe if you just specified the expression "fantasy feel" a bit...

This will be a bit longer explanation, it took me a while as well, when I was beginning with Irrlicht, but when I got into it, I found out that I've learnt quite a lot about Objective Oriented Programming (OOP) during the process.

So - I will presume that you know a bit about class inheritance and ...

The cooling texture just defines, how much the fire should cool in the place of a certain pixel. This texture then gets shifted, when animating the fire.

Just create your own grayscale texture, which defines the cooling. It should have the same dimensions as the generated flame texture.

Nice work man! I'll definitely take a look at it!

In fact, Irrlicht doesn't support materials as such, it just uses the textures and texture mapping coordinates (as far as I know).

Hello, dear fellas! I am pleased to present another scene node from my lab to you today. It is a nice fire scene node without the need to use particles. Watch the results:

As with all custom scene nodes, all you have to do is create a new instance, make it ...

You'd better create your windows as separate models and then add them to the truck scene node as children. To make them transparent, you just have to change the material properties of the nodes. e.g. : You could use following code, privided that your window glass texture has got an alpha channel ...
