Irrlicht Engine

That feature would be really nice

Hi


Currently I use a static octree for my static stuff.

The apps goes down the octree and see what cubes are inside the frustum,
normally it should do a speed increase, But my test showed it wasn't faster.

I have found out a very big speed problem, it's described here:
http://irrlicht ...

Hi

Currently with my octree culling scenenode I manage to have 90000 Objects without a lockup ~4fps and display ~ 200 triangles that are in the frustum.

The really big problem I have it's the rather slow OnPostRender function. Currently the analyse shows it's 53% the time of running in it ...

I am open to other datastructures...

Hi

You don't get any speed improvement when you look on all nodes,
or I don't get one.
Somehow using the autoculling only doesn't work right.
I don't know why, but when I look exactly from top to my landscape nodes (but only a portion can be seen) I tries to draw all nodes .
:shock: Niko, is this ...

I changed the design and now have a static octree in a SceneNode,
if you want to create your own:

I made an pirvate octree class that get init by a box and the devides to a specific depth.
Overloaded addchild, removechild of the OctNode Class.


Some Pitfalls:
Currently I don't know how a Node can ...

Let's sum up:
For most people terrains with only a bunch of extra nodes can use the normal Irrlicht Octree mesh for terrain and do the other stuff with the autoculling.

If you have a lot of nodes/objects you need a better autoculling in the scenemanger or something different.

I like nikos idea of ...

I haven't yet found a way to compile it in one pass under Win2000:
I did:
Compile it until it says it can't dllwrap.

Copy makefile.win to irrlicht.mak or any name you want.
In Irrlicht.mak change linkobj line so it has only LINKOBJ = <path>/*.o $(RES)
Change the project options -> makefile so it ...

Octree is only a datastructure, aka, you devide a cube to have 8 smaller cubes, guess what an Quadtree makes? :D
It's not limited by definiton to only be used with triangles.

Niko said he has an scenenode that culls the children somehow.
I don't know if it's static or dynamic, and how it culls it ...

Hmm, looks like I need to write my own system

Niko? You don't have such a code already, I don't want to reinvent the wheel.

There is a free version of VB to create activex controls,
in a control you can add all standard controls. It's called vb5cce. Visual Basic 5 Control Creation Edition.

If I remember correctly you can create various size controls with it, and aswell save the control. I think the tool needs only a ...

As you see, I am interested :)

A terrain I want to display aswell with these objects, so it looks like it's the same. Currently I draw my two polys via drawIndexedTriangleList. Currently my opengl testwindow with 75x75 simple terrain objects is showing with 18fps :? Not very good compared to the ...
