Irrlicht Engine

Aye, I second that.

My problem at the moment is, the question "what performance is irrlicht capable of ?".
If I cant display 10 animated Meshes simultaneosly (so no need to think about
culling at this point) without killing my fps, I simply cant use irrlicht.

I was far enough away from the nodes. In fact I can keep moving away s long as i like. I decreased the FarValue of the camera and it pretty goodssems to cull the OctTreeNodes when I cant see them anymore. But the AnimatedmeshSceneNodes allways use up my FPS. Its not the problem to implement culling ...

Ok, not that I do not believe you, but then I got problems understanding something : I just did a simple test with the Hello World demo. I added about 10 animated scenenodes of sydney, that drops the fps drastically. Adding 10 OctTreeNodes results in the same fps decrease. But then I turn around so ...

Thanks, thats helpfull. I think, my main problem is, that I do not completely understand what irrlicht does about culling etc. The OctTreeSceneNode is the only node, that gets culled by the cameras aabbox ? So I will have to handle every other node myself, using "intersectsWithBox()", if i...

ICameraSceneNode does NOT automatically react on mousemovement.
(ICameraSceneNodeFPS does)
You will have to implement that yourself.

Linepicking wont help me, since it will hide large objects if only a part of them is blocked. But atm I am pretty confused aboute the culling already done by irrlicht. I could not find a reference which nodes get culled under which circumstances. Can anybody tell me where I get information on that. ...

Hi I got a problem with the FPS on my irrlicht program. The combination "scene_manager->draw_all()" with many "IAnimatedMeshSceneNodes" seems to kill my framerate. - Is there a way arround "draw_all()" ? Should I build a mesh selector to choose which meshes to update vi...

Great, third time, I answer this thread, and it just gets lost somewhere. @ sourada : I implemented a externel camera very similarto yours. It works fine , but since I used the normal cameraI have to map the mouse movements to the rotation. Maybe Im just stupid, but I cant get it done smoothly. How ...

A while ago I tried to set up a primitive 3rdperson camera using the FPS camera. I encountered a few problems and went for a different solution, but that thing still bugs me. I'm merely getting the cameras orientation an move it to look at the desired target. And somehow this results in massive jitt...

Yep, thats what I'm doing. Atm I'm getting the transformed bbox everytime i need it, instead of updating; works fine. But the problem is that I'm additionally using the "usual" irrlicht collision detection, to prevent objects from intersecting, which results in the effect that objects whic...

virtual ISceneNodeAnimatorCollisionResponse* irr::scene::ISceneManager::createCollisionResponseAnimator ( ITriangleSelector * world, ISceneNode * sceneNode, const core::vector3df & ellipsoidRadius = core::vector3df(30, 60, 30), const core::vector3df & gravityPerSecond = core::vector3df(0,-1...

No thats not what I mean. Irrlicht uses Triangleselectors to calculate collisions. And the basic way is to use a CollisionResponseAnimator with a sceneNode, which takes care of the "movementreactions". So you "take a node", and a few triangles an tell the Animator to manage colli...

Simple question :
When setting the ellipsoid values for the collisionResponseAnimator,
how do you get "good values" to accurately represent your object/modell etc.?
Just take the boundingboxes heigth, width and legth as the radiuses,
or is there sth. better ?

Hi there, I'm trying to manage the results of a collision between objects, which do not simple "block" each other. All my "blockable" objects are managed via triangleselectors, and collisionresponsanimators to prevent them from intersecting etc. But I got additionaly objects whic...
