Irrlicht Engine

Yes, a mesh is a model (vertices, indices, tcoords).

you can. Just open (or create) a blank IImage object, having the size that you want, and apply whatever terrain generation algorithm that you feel like using (I personally like perlin noise, mostly for its simplicity ).

That's what the documentation's there for

remember that you have to set the fog flag to true on the material on the node that you wanna have fog in.

Also, getHeight funtion of terrain node currently returns false all the time (it's not implemented yet), so you might want a different method to place the trees.

FOV in Irrlicht uses radians (3.1415 = 180 degrees) so all you have to do to set a 90 degree FOV is camera->setFOV(3.1415f/2.0f);

It's done this way because it is faster than to check the object's position relative to the 6 planes. You may get more objects drawn, but it still should be faster than the pickier method.

try camera->setFOV(3.1415f/2.0f);

that should give you a 90 degree field of vew, eliminating any fish eye view thingies and problems.

It's not, I've just been away for a while :)


I've been redoing the data structure holding the vertex data, but I can't seem to find a feasible option to a having huge vertex buffer, and giving each quad tree node to have only pointers to the vertex data.

I've been toying with the idea of ...

get the vector3df from ISceneCollisionManager->getCollisionPoint(), and do the following:

ISceneCollisionManager *cols = smgr->getSceneCollisionManager();
while(device->run())
{
vector3df point = cols->getCollisionPoint(fill in vars here);
wchar_t tmp[1024];
swprintf(tmp, 1024, L"X:%f Y:%f Z:%f ...

yup, just get the color data from each texture, and blend it at will, then create a third texture and substitute its color data with the blended texture data.

I saw in your demo that you change the LOD on a per patch basis, do you calculate your indices interactively, or at load time?

I'm having some troubles setting the translation of a bounding box for view frustum culling (as in I can't see a single thing being drawn). Here's the code:

[code]
bool isQuadVisible(SViewFrustrum *cam, QuadNode *node)
{

aabbox3d<f32> pointBox(node->vertices[4]->Pos);
pointBox ...

well, in a custom scene node, you always need to get the scene manager from the irrlicht device, so from there, it's just a call to smgr->getActiveCamera() and you get the camera node pointer!


Btw, im also working on a terrain rendering node, using quad trees. However, I'm currently working on ...

ICameraSceneNode *->removeAnimator(ISceneNodeAnimator *);

this should work, provided you haven't dropped the animator pointer, although im not sure if it works even after that, as I haven't tried it.
