How I can start in the center of my mesh?

[Gideon]

How?

[Acki]

I think you mean node, not mesh...
you can try it with:

Code: Select all

vector3df cntr = node->getBoundingBox().getCenter();

but I doubt that is what you want...
it's not that easy though, because a mesh usually is more complex...

[Gideon]

All good yet, but I have again the problem.
Look:
From above:

From below:

Whay is it?

[Acki]

What is it?

I don't know, tell me what you expect and what you get...

[Gideon]

This is a *.b3d world. It's like good in the Gile[s] and 3ds Max, but when I have load it... i see this.

[vitek]

It looks to me like the normals are on the wrong sides of the resulting mesh. I don't know if this is a problem in the mesh itself or if it is a problem with the reader code.

Code:

is that even vaguely like it should look?

it's probably nothing to do with normals as normals are just used for lighting and this clearly isn't a lighting issue.

more likely the triangles are wound the wrong way round so they're facing the opposite direction to where they should be facing. so you've probably got backface culling turned on so you don't see the backs of the triangles which in this case you would want to, you can change this parameter in irredit under the materials section. but of course for efficiency's sake you'd want backface culling on and for the triangles to be wound correctly, which would have to be sorted out in your modelling program.

[Gideon]

In the IrrEdit I have seen the same. Where the "face" function in IrrEdit? I did not found it.

[JP]

Sorry i thought you were using irredit but you're not (or not in the screenshots anyway), it's not necessary to use irredit for this but you can do. it's in the materials tab of the node, bottom left when you have the correct node selected, scroll down a bit and there's a tick box to turn back face culling on or off.

In irrlicht though you can set it like this:

node->setMaterialFlag(video::EMF_BACKFACE_CULL, false);

I think that's the right enum, you might have to check the API if it doesn't compile!

[Gideon]

This is not work...
The compiler write me:

`EMF_BACKFACE_CULL' is not a member of `irr::video'

Why?..8(
P.S. May be use in 3ds Max the Modyfi "Normal"?

[JP]

It's not working because you didn't read the last line of my post...

[Gideon]

Sorry, man. But I did not find in your post the answer on my qestion... Don't damage me, please...
I speak English very-very bad...=( What I must do?

[JP]

Read the documentation/API to find out the correct enum to use. Maybe it's EMF_BACK_FACE_CULL.

[Gideon]

Thank's, man. I can complited my world and I very happy now=) Biiiigggest thank's!
