Irrlicht Engine

Another little typo:

virtual const core::vector3df irr::scene::ISceneNode::getRotation ( ) const

Sets the rotation of the node.

Ok, that confirms my version... thanks!

I think that the FOV in buildProjectionMatrixPerspectiveFovLH/RH
methods are wrong calculated.

In fact, if I restrict the field of view I obtain a zoom out, not a zoom in.
I also tried a patch found at hybryd page, but it doesn't work.

Then I looked the GLUPerspective function:
http://developer ...

Update... =)


If I change

mat.transformBox(invbox); with mat.transformBoxEx(invbox);

in function COctTreeTriangleSelector::getTriangles (COctTreeTriangleSelector.cpp)

all collisions work well...

Bug? Feature? Error in my code?

Anyway, now my program seems to work! =)

I created a custom SceneNode and I used createTriangleSelector function for collisions:

[...]
selector = SceneManager->createTriangleSelector(&s_mesh, this);
[...]
collision->getCollisionPoint(ray, selector, v, t)
[...]

and all collisions work well! =)



But if I use createOctTreeTriangleSelector ...

Ok, maybe I'll modify the source code... =(

Thanks!

Can I use different colors for different menu items?

For example:

Menu: File
Menu items: Open(in blue), Exit(in black), etc.


Thanks! =)

Maybe this is a stupid question... ^__^
Anyway...

My GUI with antialiasing is very... ugly! (in my opinion) O_o
Can I draw my scene with antialising and GUI without antialiasing?
Eventually, modifying the Irrlicht source code...

Thanx!

Well, I found how to implement it in D3D =)

I must add in CD3D9Driver::drawIndexedTriangleList these lines:

pID3DDevice->SetRenderState(D3DRS_DIFFUSEMATERIALSOURCE, D3DMCS_COLOR1);
pID3DDevice->SetRenderState(D3DRS_AMBIENTMATERIALSOURCE, D3DMCS_COLOR1);
pID3DDevice->SetRenderState(D3DRS ...

With glColorMaterial, I can change the material's color for each vertex and not only the vertex's color.

For example, if I enable lighting (and add some lights) in CustomSceneNode tutorial, the object appears "white and black":

If I add glEnable(GL ...

Hi,
I have this code (in OpenGL):

[...]
glEnableClientState(GL_COLOR_ARRAY);
glEnableClientState(GL_NORMAL_ARRAY);
glEnableClientState(GL_VERTEX_ARRAY);

glColorPointer(4, GL_FLOAT, 0, color_p);
glNormalPointer(GL_FLOAT, 0, normal_p);
glVertexPointer(3, GL_FLOAT, 0, vertex_p);
glDrawArrays(GL ...

I am not sure...
Anyway, I recompiled the engine =)

Great, it works! =)

Thanks!!

I have a problem with light/material... =(

I created a simple custom scene node.

I added a light:
light = scene_manager->addLightSceneNode(0, camera_position, SColorf(0.3f, 0.3f, 0.3f));

And I used a material with these parameters:
material.AmbientColor = SColor(255, 20, 20, 20);
material ...
