Description: 本题写了一个EE3的产品描述，是四维的。确实很难想像清楚。我们这样想就行。它有四个坐标，每一维都可以放上一个立方体，边长为1.然后就是怎么判断是否Inconsistent，有两种情况：1），如题上举的例子，ID为1的在x2坐标上前面是3，那么ID为3的在X2坐标的后面应该是1，否则就Inconsistent。-We usually think that there are three geometric dimensions the fourth dimension is usually time. However, the Association for Customizing Machines (ACM) has to deal with four geometrical dimensions for their strange customer EE3 who needs to pack four dimensional products into perpendicular parallelepipeds before shipping them to the newly emerged market niche just on the outskirts of the Milky Way.
Each of EE3 products consists of a number of unit 4D cubes that are glued together at their faces. A face of a 4D cube is a 3D cube and each 4D cube has 8 such faces. The picture on the left shows a 4D cube projected into a plane with the four principal, orthogonal axes shown. It takes a bit of effort to stretch our imagination and see the faces of a 4D cube in such a projection. The pictures below try to illustrate how the two faces along each of the four axes are situated in 4D. Again, using just the planar projection it is not so easy to illustrate and takes some effort to see. But we

future. Check this file for information on latest update.
The following files are presently included:
GRID.F This file contains a code for generating 3D Cartesian multigrid
grids. Its main part is the 2D grid generation code described
in more detail in directory 2DC. In addition, it is also used
to set boundary conditions, since the type of boundary for
CV-faces along boundaries can be prescribed by assigning a
particular value to an integer array identifying each boundary
cell face. More details will be given for the updated version.
DG An example of input data for the above code it generates a
non-uniform grid for a cubic cavity as used to predict flows in
lid-driven cavities.

Description: real-time 3D pointing gesture
recognition algorithm for natural human-robot interaction
(HRI). The recognition errors in previous pointing gesture
recognition algorithms are mainly caused by the low performance
of the hands tracking module and by the unreliability
of the direction estimate itself, therefore our proposed algorithm
uses 3D particle filter for achieving reliability in hand
tracking and cascade hidden Markov model (HMM) for a
robust estimate for the pointing direction. When someone
enters the field of view of the camera, his or her face and
two hands are located and tracked using the particle filters.
The first stage HMM takes the hand position estimate and
maps it to a more accurate position by modeling the kinematic
characteristics of finger pointing.

Description: In this paper, we present a comparison of four novel algorithms
that have been applied to the tracking of people in
an indoor scenario. Tracking is carried out in 3D or 2D
(ground plane) to provide position information for a variety
of surveillance, HCI or meeting-support services. The
algorithms, based on background subtraction, face detection,
particle filter feature-matching and edge alignment
of a cylindrical model are described and comparative results
presented using independent test data produced and
ground-truthed for the EU CHIL project.

Description: 四棱锥由5个面构成一个封闭的立体图,其中4个共顶点的侧面是三角形,底面是个四边形。如果我们要绘制一个3D的四棱锥只需要绘制这5个面即可，绘制的方法和前一篇文章OpenGL_Qt学习笔记之_03(平面图形的着色和旋转)的相同。只不过这里的顶点坐标是3维的，所以图像深度那一维不一定为0。因此我们可以事先计算好四棱锥各个顶点的坐标，这对学过立体几何的人来说应该是小case了。然后绘制每个面就可以。
注意，在opengl中绘制每个面时，所有面给出的顶点的顺序都要按照逆时针或者顺时针(我这里采用的是逆时针)，这样才能保证所绘制出来的图像时正确的。
现在我们在paintGL中开始绘制四棱锥，如果按照NeHe的教程，它只是绘制了个金字塔，并没有底面，只有4个侧面，这里，我采用它的方法，代码如下: -A closed perspective view of four-sided pyramid is constituted by 5 surface, wherein the side of vertex 4 is triangular, the bottom surface is a quadrangle. If we want to draw a 3D pyramid only need to draw the five faces can, the drawn and former article OpenGL_Qt study notes _03 (planar graph coloring and rotation). But here vertex coordinates of a three-dimensional, so the image depth that dimension is not necessarily 0. So we can be calculated in advance the good four-sided pyramid coordinates of each vertex should learn solid geometry, is a small case. Then you can draw each face. Opengl in draw each surface, all surface given vertex order must be in accordance with the counterclockwise or clockwise (I used counterclockwise), so as to ensure the drawn image. Now we start drawing in paintGL four pyramid NeHe tutorial, it just draws a pyramid and the bottom surface of only four sides, here, I adopt its methods, the code is as follows:
