查询词典 virtual object

The binary + operator performs string concatenation when one or both operands are of type string. If an operand of string concatenation is null, an empty string is substituted. Otherwise, any non-string argument is converted to its string representation by invoking the virtual ToString method inherited from type object.

由此可知 C#的加号运算子预设就支援字串串加的功能，只要一群字串串接的物件中只要有一个以上的物件型别是「字串」的话，就会全部变成「字串相加」，只要遇到「非字串」的物件，预设会使用继承至 object 物件的 ToString 方法进行转型，让所有物件都变成「字串」后进行相加动作。

The main contents and results of research in this paper are shown as following: It is important to built the motion model of a virtual system. As the virtual object is the submarine in this simulation system, we studied on the motion model of the submarine and gave the submarine six DOF space motion equation MultiGen-Paradigm corporation's modeling software named Creator is used, the modeling of all entities and 3D terrain in virtual ocean environment is accomplished. Then introduced the theory of Large Area Database Management and realized the Large area database management; In the course of 3D scene simulation, Vega is utilized to develop the project. The building of 3D scene is done, which includes the simulation of static and dynamic ocean surface, realization of ocean wave, simulation of bow wave and stern wake, utilization of lighting and material, simulation of cloud and fog, kinematics' modeling of submarine etc.

论文的主要研究工作和成果包括以下一些内容：建立虚拟对象的运动模型是构造一个虚拟系统的关键所在，建立的运动模型准确与否直接关系仿真对象模拟的逼真度，由于本仿真系统的虚拟对象是潜艇，所以对潜艇的运动模型进行了研究，给出潜艇空间六自由度运动方程；利用MultiGen-Paradigm公司的Creator建模软件完成虚拟海洋环境中个实体模型建模和三维海底地形模型的建模；然后介绍了大地形数据库管理(LADBM，Large Area Database Management)技术的基本原理，实现大地形数据库管理；在三维场景仿真中，使用Vega驱动软件进行软件开发，完成了三维场景空间的建立，主要包括动态和静态海洋的仿真、海浪、船首波浪和传尾尾迹的实现，灯光和材质的使用，云和雾的模拟等。

The heart of this algorithm is to track at least four fiducial points from frame to frame that construct the affine frame, thus the occlusion contours between virtual and real objects can be reconstructed and reprojected. Further, each contour is labeled as being "behind" or "in front of" in the first two frames, depending on whether it is in front of or behind the virtual object, so the occlusion is resolved.

该算法的核心是在每一帧图像中追踪至少四个基准点，构成仿射基，进而对虚拟物体与真实物体之间的遮挡轮廓进行重建和重投影，且在前两帧图像中交互指定这些阻挡轮廓相对于虚拟物体的前后位置，从而解决了扩充现实的阻挡问题。
