Irrlicht Engine

Yes, you're absolutely right, it is a method of BulletPhysics. With nodes Irrlicht I define the position and rotation of the sensor. And uses this information to generate endpoint RayTest.

Another function is the "btDiscreteDynamicsWorld :: rayTest" ... with help of this method, I want to find the nearest object. On GitHub have forks that allow this method to run in multiple threads ...

I wonder ... Tell me, ISceneCollisionManager :: getCollisionPoint faster than g_PhysicalWorld-> GetWorld () -> rayTest (Start, End, RayCallBack)? And whether it is possible to perform ISceneCollisionManager :: getCollisionPoint from multiple threads? Should I use ITriangleSelector * selector or can ...

Thank you. I understand you offer not do a few RayTest, and instead create a sphere with which to check the intersection of objects? I just have hundreds of such sensors and to me it is very important to quickly calculate their ...

Well, thanks for the quick response, I have been working in this direction. I will describe the problem more generally, I imitate the sensor field of view and want use the method RayTest to check the presence of an object in a certain region, for that I generate endpoints with little extensibility i...

Good afternoon. I am using addMeshSceneNode(_Mesh) to create a graphic node. _Mesh is SMesh, and I create by specifying the vertices of triangles. Next, I need to get the coordinates of the vertices at the offset, rotation, and scale of the node. In the SMeshBuffer coordinates are not changed. How c...

Thank you very much. The class that you recommend doing exactly what I need. Since computation physics and rendering scene are performed in different threads, I do not need very high performance graphics engine. I was a little changed your class and spread it here, all of a sudden someone else will ...

Well, I mean ... Tell me, then, please, how do I determine the correct origin and rotation the child node relative to the parent.

Is it possible to easily add the appointment of child nodes of the parent node flag application scale? Maybe it would even increased performance - it is not always necessary to use the parent node scope. I use Irrlicht to display the results of the Bullet Physics, and there is a class with the aid o...

Please try this:   #include "stdafx.h" #include <irrlicht.h>   using namespace irr;   #ifdef _MSC_VER #pragma comment(lib, "Irrlicht.lib") #endif   int main() {     IrrlichtDevice * Device = createDevice(video::EDT_OPENGL, core::dimension2d<u32>(1280,1024) );     if (!Device)    ...

Thanks for the quick reply, but somehow it does not work. I add child node with a turn and it is distorted (child node is created as g_GraphicalWorld-> SceneManager () -> addMeshSceneNode (.....); bluish transparent tetrahedron shown in figure is child node).If turn the child node relative parent is...

Is it possible to disable or compensate of scaling child node when the assignment of its parent?

Node field of view is created and rotated with the right size, then she is clinging to the sensor node, and if I understand correctly, to the node of the field of view of the scale of the sensor node is used, which distorts the node view.

Well, why do I get by dividing the vector. And the scale is used for all three axes.
I think here the reason is different: the scale is applied to the child node after the turn. How to avoid it?

Good afternoon. I imitate the sensor field of view (transparent triangle), which is ISceneNode given from SMesh. The field of view as a subsidiary node clinging to the sensor node, which conditionally scale (1, 1, 2). When I cling to the node of the field of view of the sensor I give it the scale to...
