Irrlicht Engine

I found a solution that is good enough for me: a special caustics lightmap generator.
This seems to be the proper english name for the effect I was searching for: the caustics effect.
And there is a free generator: http://www.dualheights.se/caustics/.

You could combine the lightmap and texture map into one file, then use the detail map. You could write a shader to do it. Or you could try and draw your object twice. Those are the only three ideas I have.
Thanks for the input.
To combine the lightmap and the detail map came to me last night too ...

Hello,

does anybody know the old Aquanox games?

The setting is under water. The terrain uses a diffuse map, a detail map and an animateted light map to visualize the sun light refracted by the surface waves.

From what I know from Irrlicht I can only use EMT_DETAIL exclusive or one of the LIGHTMAP ...

polycount.com was down for years ... so thanks for the message that it is up and running again! Now there seem to be less models than before though.

Hi

@rogerborg: Thanks for you ironical hint.
I was under the impression that it should be possible to draw a font to an image or texture and use just 2D-methods to acomplish this task.
I still can't believe that I have to use a camera to take a 2d-picture of a 3d-world to move a 2d-graphic (some ...

Hi again

thanks for the answers.

@sp00n: I will look into createImageFromData()

@JP: I have no clue how to render a text into a texture. Do you have an example?

Hi there,

in order to avoid drawing a text every frame to the screen again and again I want to draw text to a texture and display this texture instead. So I have to redraw that texture only if the text changes.

But I have no idea how to draw text to an image or a texture with Irrlicht.

I suppose ...

Thanks vitek/Travis!
That's it indeed. It works now :D

But I still have one related question:
Why is the value of "node" available in receiver.OnEvent() then?

I am still talking about the original examples/04.Movement.

"node" is initialized just the same as device:

scene::ISceneNode* node = 0 ...

I personally think that Blitz3D http://www.blitzbasic.com/ is a pretty good environment for 3d-starters.

What I found nice:
+ never saw an easier or faster way to get results
+ every programmer knows BASIC
+ free demo version available for download. works 30 days (?)
+ huge active community (in ...

The problem is that device is an unvalid pointer.
Yes, that's what I thought too.

But it shouldn't, should it? Cause device is global and get's initialized right in the beginning. Same is with "node", that is used without a problem four lines below.

So if device can not be used here, how should ...

Thanks for telling me that, BlindSide.
But the problem remains the same. I just tried it with the original Movement Example 04.
I added only the three lines as mentioned above and I get a crash every time I hit "Q"-Key.

...
if (node != 0 && event.EventType == irr::EET_KEY_INPUT_EVENT&&
!event ...

Hi.

I want to stop the IrrlichtDevice, so that device->run() will result to false.
And I want to do this as a reaction of a key event.

EDIT: I tried the following inside the Example 04 (Movement).

I tried:

...
class MyEventReceiver : public IEventReceiver
{
public:
virtual bool OnEvent(SEvent ...

Hi

I am searching for a 3d-lib that help me simulate a real space environment. I need to image at least a satellite rotating earth and earth rotating sun.

But with a basic floating point data type of 32 bit (Irrlicht's f32) this seems impossible, cause it only covers a precision of 6 digits.

It ...

Suggestion
After playing around with the skin object I suggest to change the background color in CGUIEditBox::draw() of an edit box with border from EGDC_3D_HIGH_LIGHT to EGDC_WINDOW.

Why do this?
First of all, it woud not change the look of a standard application that has not changed the skin ...

... and me again

Just found out that I can use My3DTools to import from Gile[s].

But please answer my first questions, see above.

Thanks in front.
