Irrlicht Engine

Question:

You project the light onto a plane (TerrainSceneNode) ?

This object does not provide the required normals?

Thanks. Good reading material.

I am having problems with Physx. My simulation looks slow. Only if i set the time step to 1/20 it gets a bit more realistic. But of course setting the timestep to 1/20 is not fixing the cause, just the effect.

Anybody knows the ratio recommended for Physx ?

Any new updates on this?

Looking forward

It might make sense to create two custom classes (but derived from the same base class). Each one will have it's own camera. when you select from one to another, each element will have it's associated camera.

More than one camera can co-exist. You just select which camera is active at a moment ...

The shader callback is called every frame. Loading a picture (texure) takes quite a lot of time.

In a shader callback you typically do not load anything, just send data to the uniform variables.

I used the same code ( or most of it ). It looks the same.

You are also using DirectX. I am using OpenGL.

Can you please explain how you do that in the shader?

I am not sure what wxWidget is your irrLicht window. Is it a wxControl or a wxWindow? You must make sure that the control or window in which you have the irrlicht 3d window is having the focus. Otherwise it simply does not receive the messages, since it does not have the focus. You can give it the ...

- animated meshes don't animate, they only move to their first frame.

You must add a tick call, just before beginScene:

GetIrrDevice()->getTimer()->tick();

- IRRlicht cameras don't have the proper aspect ratio (I think its because of the wrong information about the display size)

Add this ...

Isn't this similar to:

What settings did you use for this

irr::scene::IMesh* tangentMesh = smgr->getMeshManipulator()->
createMeshWithTangents(mesh->getMesh(0),
true, // recalculate normals
false, // smooth
false, // angle weighted
true // recalculate tangents
);


I've used several models (copied from ...

If all the industry is calling it binormal........

And this is not the point here. The point is calculating them, as it is clear that there is an issue with irrLicht.

@Luben

Most important is to define and explain them. I don't care how you call them, i need to know what they are and how to calculate them.

Thanks, i knew i was missing something. I am using the very same 3ds file in RenderMonkey and in irrLicht, but i am getting different results.
Only normals are loaded from the file, tangent and binormal are calculated by irrLicht.
