Divide each plane of cube by its median without loop

I think the issue was by ths following , You can pass a list of axes to np.median and then expand via None (np.newaxis):
code :
>>> cube = np.random.random(100000).reshape(10,100,100)
>>> simple = cube / np.median(cube,axis=[1,2])[:,None,None]
>>> brute = cube.copy()
>>> for i in range(10):
...     brute[i, :, :] /= np.median(cube[i, :, :])
>>> np.allclose(brute, simple)

I wish this helpful for you This is a known limitation of CanvasRenderer.
You can reduce these artifacts by increasing the tessellation of your geometry -- particularly the plane.
code :
var floorGeometry = new THREE.PlaneGeometry( 1000, 1000, 10, 10 ); // will help
var cubeGeometry = new THREE.CubeGeometry( 50, 50, 50, 2, 2, 2 );  // may help

hope this fix your issue Your problem is that the camera and the plane both have the same Y coordinate. You never specified any position for the camera, so it is at the point (0, 0, 0), so its Y coordinate is 0. You also specified the coordinate of the plane to be (0, 0, 10), so its Y coordinate is also 0. Since the Y coordinate is up in Irrlicht, this means that you are looking at the plane from the slice like in this drawing:
code :
plane->setMaterialFlag(irr::video::EMF_LIGHTING, false);
driver->beginScene(true, true, irr::video::SColor(255, 255, 255, 255));
irr::IrrlichtDevice *device = irr::createDevice(irr::video::EDT_OPENGL);
irr::video::IVideoDriver *driver = device->getVideoDriver();
irr::scene::ISceneManager *sceneManager = device->getSceneManager();
const irr::scene::IGeometryCreator *geomentryCreator = sceneManager->getGeometryCreator();

irr::scene::IMesh* plane = geomentryCreator->createPlaneMesh(irr::core::dimension2d<irr::f32>(100, 100), irr::core::dimension2d<irr::u32>(100, 100));
irr::scene::ISceneNode* cube = sceneManager->addCubeSceneNode(20);

irr::scene::ISceneNode* ground = sceneManager->addMeshSceneNode(plane);
ground->setPosition(irr::core::vector3df(0, 0, 10));
plane->setMaterialFlag(irr::video::EMF_LIGHTING, false);    //This is important

irr::scene::ICameraSceneNode* cam = sceneManager->addCameraSceneNode();
cam->setPosition(irr::core::vector3df(0, 50, 0));    //This is also important

    driver->beginScene(true, true, irr::video::SColor(255, 255, 255, 255));    //Important for the background to be white

hop of those help? With Legacy OpenGL fixed function pipeline you can set a clipping plane.
There can be more than 1 clip plane and the planes have to be enabled by glEnable(GL_CLIP_PLANEi).
code :
plane = plane = [-1.0, -1.0, -1.0, -280]
ogl.glClipPlane(pgl.GL_CLIP_PLANE0, plane)
def on_draw(self) :

    pgl.glClear(pgl.GL_COLOR_BUFFER_BIT | pgl.GL_DEPTH_BUFFER_BIT)

    pgl.glViewport(0, 0, 500, 500)

    pgl.gluPerspective(45, 1, 1, 1000)

    pgl.glTranslatef(0, 0, -400)

    pgl.glTranslatef(self.x, self.y, self.z)
    pgl.glRotatef(self.xRotation, 1, 0, 0)
    pgl.glRotatef(self.yRotation, 0, 1, 0)
    pgl.glRotatef(self.zRotation, 0, 0, 1)
    pgl.glScalef(self.zoom, self.zoom, self.zoom)

    if not transparant:
        pgl.glPolygonMode(pgl.GL_FRONT_AND_BACK, pgl.GL_FILL)
        pgl.glPolygonMode(pgl.GL_FRONT_AND_BACK, pgl.GL_LINE)

    # set and enable clip plane
    plane = plane = [-1.0, -1.0, -1.0, -280]
    ogl.glClipPlane(pgl.GL_CLIP_PLANE0, plane)

fixed the issue. Will look into that further As @PaulPanzer pointed out, I was dotting the new vector from the wrong direction. The solution is
code :
np.dot(NE_1, NEW_SPACE)
