Description: Photogrammetric space intersection requires image coordinates of a point in space to be digitized
on two or more photos. In digital photogrammetry or in single photo digitizing, it is difficult
to locate the matching image of poorly defined points on different photos. A mathematical technique
has been developed that requires only that lines or features be digitized on different photos
without the need to digitize the same image points to perform the intersection. This method is very
useful in single photo digitizing and 3D robot vision.

Description: MATLAB作为成熟的科学计算软件，其绘制三维实体模型的功能已经非常完善，要实现三维实体模型间的运算也比较容易，然而Scilab 的绘制三维形体模型的功能还不够强大，三维形体模型之间的布尔运算也比较困难，因此有必要开发一个绘制三维形体模型并实现并、交、叉运算的工具箱，来强化Scilab的绘图功能。
本项目组开发的《基于CSG的三维形体建模工具箱》实现了三维形体建模和绘制功能，用户不仅能依据给定的参数直接绘制简单的三维形体，还可以对三维形体进行平移、旋转和比例缩放操作。多个形体之间可以通过正则布尔运算(并、交、差运算)得到新的三维形体，方便用户利用多个简单形体构建复杂的三维形体。
-As a mature scientific computing software, MATLAB s function of rendering three-dimensional models is very good, and it is easy to achieving three-dimensional solid models’ operation. Compared with MATLAB, Scilab uses relevant functions to render three-dimensional models is not strong enough. And it is also difficult to implement the Boolean operations among three-dimensional shapes. Therefore, it is necessary to develop a toolbox to implement functions of modeling and rendering and the operations of union, intersection, difference to strengthen the drawing function of Scilab.
This project <CSG-Based 3D Modeler Toolbox> implements functions of CSG-based modeling and rendering. Users not only can make and plot simple three dimensional shapes, but also can translate, rotate or scale the shapes. It is convenient to make a complicated shape by some simple unit shapes, for simple shapes can be composed into a complicated shape by regular Boolean operations- union, intersection, and

Description: 研究了三角形表面模型的布尔运算。传统的CSG 算法是基于基本实体的布尔运算进行的，对于由三角形或多边形描述的表面模
型的复杂模型运算则十分困难。通过构建模型的BSP 树，利用BSP 树的空间分割能力，把参与运算的模型分割成两部分，然后，根据交、并、差
各种布尔运算，组合分割后的结果，实现了不规则三维模型的布尔运算-Researched on Boolean Operation of triangle facial model. Traditional CSG algorithm based on the Boolean Operation of primitive
solid model, which hard to deal with the complex model defined by triangles or polygons. Construct the BSP Trees of 3D models, using the ability of
space partioning to divide up the model into two partions，and then，you will get the Boolean Operation results such as intersection, union, difference
by combine different partions. Implemented the Boolean Operation of unregulated 3D model.

Description: Computer Graphics: The geometry of the shape must be defined by implicit functions. You must use
in the function script at least one set-theoretic intersection, one union and one
difference operations implemented using min / max functions. Using symbols of
these operations ( | and & ) is not allowed.
The geometry of the shape must be created using at least one ellipsoid,
cylinder, cone, box, and blobby object.
A 3D texture defined by an explicit displacement function has to be applied to
the shape.
The color of the shape must vary across the shape’s surface and be defined by
parametric functions.
