Irrlicht Engine

Awesome thread.
Comment the code a little more extensively and put this into irrLicht tutorial!

but it always circle around (0, 0, 0) You use no origin in your calculation, that is why its circling around 0,0,0.

And there is also distance to origin which you need to take in to account somehow.

I made tutorial which shows two methods to turn node around origin: Turn around origin in 3D

I ...

I successfully circle around with my scene node (cube object) but it always circle around (0, 0, 0).
What do I have to do to make it circle around some specified point like (100, 100, 100)?

My current code

core::vector3df my_rotation4 = my_cube4->getPosition();
core::matrix4 n;

if(receiver ...

How would I rotate scene node around local axis (not world ones like rotateYZBy does)?

So, for example, that if I want to rotate around target up and down no matter at what side of target I am I always rotate around X axis.

Of course I would always have to turn to face the target so that my Y axis ...

OpenGL 1.4 hints for either an outdated driver, or a very weak onboard gfx card, though. Could be that you're out of luck getting better results with your actual HW. Could you please post the output of one of the other examples (5 or 6 would be good).

Yea, those examples 5. and 6. are good.
But ...

Most common problem after a new install is that the hardware drivers are not installed. And it might look somewhat like that if it's using something like Mesa instead.

Do type into the console:
glxinfo | grep direct

It should return something like:
direct rendering: Yes

If it says no instead ...

So I installed new Ubuntu 9.10 and Irrlicht 1.6, compiled the examples and there is an error. When I look around only textures that are in close proximity to myself (sphere around me) are rendered, those further outside are black.

Example on 02.QuakeMap example (Sry for whole screen but Gimp is not ...

I want to rotate the camera around an object (her target) telling camera how many degrees to rotate around specified target, so in animateNode I put:


RotX = 0.0f;
RotY = 0.0f;
core::vector3df target = camera->getTarget();

// Rotation ------------------------------------

if (CursorKeys[EKA ...

Thanks, I'll implement your proposal. momentarily I am not thinking of serialization, but you never know if I need a Factory in future.

So what is the most meaningful type value to return for custom camera animator?
As you can see from the code I return ESNAT_UNKNOWN since nothing I need is defined in enum ESCENE_NODE_ANIMATOR_TYPE .


//! Returns type of the scene node
virtual ESCENE_NODE_ANIMATOR_TYPE getType() const {

return ...

Thanks, that was just what I wanted to know.
OK, back to implemetation.

This is necessary for deserializing your scene including the animators and later on reload them again. Actually, it's only necessary for the second step (the reload), at which point the scene manager has to be able to create the animator based on the name (a string).

I got that.
But do I need to ...

To be able to add custom scene node animators to Irrlicht and to make it possible for the scene manager to save and load those external animators, simply implement this interface and register it in you scene manager via ISceneManager::registerSceneNodeAnimatorFactory. Note: When implementing your ...

Hi everybody.

I want to make an Orbiting Camera (like the Maya one when you click left mouse button) but i want to have it react to keys WASD instead so I have free mouse cursor to click around the model.
Camera would orbit around the model in space like a planet or an atom.

I have three examples ...

Whoa, how did you know.
It works!

But as I programmer I am I have to ask what causes clash between Compiz and OpenGL. How to make them work together.
Yey another problem to solve.
