Irrlicht Engine

For my project, I need to load a few meshes fully textured dozens of times each (in different positions). I also need to make them visible/invisible interactively.

The problem is that the framerate starts being really low when the number of textures/polygons of all these meshes gets huge.

So, I ...

AAAAAAAAAAAHHHHHHHH!!!!
I see!

That solves my problem (so far).

Many thanks!

Ecliptic Fate:

I want to be able to select some lines, and display information about them. I guess it must be embeded in a node somehow for that. Or not?

I did it from the main render node, and it worked great. But I still can't interact with it. How can I call it from within a scene ...

I really don't get it yet...
How can I put a line in the 3D space inside a node?
Like,


scene::ISceneNode* MyNode = 0;
MyNode = driver->draw3DLine(core::vector3df(0.0f,0.06f,0.0f), core::vector3df(55.0f,0.06f,0.0f), video::SColor(255,100,101,140));



The compiler simply tells me that there's an ...

Hummm... OK, I guess that should work, thanks.
Any clue on how can I then interact with these splines (like, select them)

Thanks.

OK, so suppose I use OpenGL (for the sake of simplicity) to generate my splines. Would the Irrlicht camera then display it?

Manual triangulation... I don't know how to do it efficiently. You see, I'll have to generate the 3d functions on the fly and then display the curves.

dhenton,

Thanks for the reply.
So, setvisible(true) solves my problem of the visibility switch.
I'm not familiar with the OpenGL API, but will give it a try, maybe it solves my problem.
Now, for the transparency your solution does not seem to work, since when you set a material type as EMT ...

Hi all,

I started to test Irrlicht two weeks ago for a scientific project.
However, I still did not find a way to implement a few essential things. Namely:
--How to draw splines in the 3D space? Like, suppose I have a function which defines a curve in the 3D space. Is it possible to render it ...
