    • A computer program and apparatus for displaying an image of graphical objects viewed from a certain eye point, which permit the user to select either a fixed up direction or a variable up direction when manipulating the eye point location. The program first determines which movement mode to use, according to a given user action. It then calculates the eye point coordinates and a line-of-sight vector according to the user action and the determined movement mode. When the mode is fixed up-direction mode, the up direction of the projection plane is set to a predefined direction. When it is variable up-direction mode, some predetermined rules are applied to determine the up direction. Given objects are perspective-projected on the projection plane being oriented in the determined up direction, based on the calculated eye point coordinates and line-of-sight vector. The resulting object image is then displayed on a monitor screen.
    • 一种用于显示从特定眼点观看的图形对象的图像的计算机程序和装置,其允许用户在操纵眼点位置时选择固定向上方向或可变向上方向。 程序首先根据给定的用户操作确定使用哪种移动模式。 然后根据用户动作和所确定的移动模式来计算眼点坐标和视线矢量。 当模式为固定向上模式时,投影平面的向上方向被设定为预定方向。 当它是可变的向上方向时,应用一些预定的规则来确定上行方向。 基于所计算的眼点坐标和视线矢量,给定对象被透视投影在投影平面上,朝向确定的向上方向。 然后将所得到的对象图像显示在监视器屏幕上。

    • There are provided a three-dimensional model display program and a three-dimensional model display apparatus, which enable seamless switching between two-point perspective projection and three-point perspective projection. A line-of-sight vector indicative of a direction of viewing an inside of a virtual three-dimensional space from a viewpoint 3 is determined in response to an operation input. A projection condition is determined that two-point perspective projection is selected when the line-of-sight vector is close to a horizontal one and that a degree of influence of three-point perspective projection on two-point perspective projection increases with an increase in inclination of the line-of-sight vector with respect to a horizontal direction. An image is generated by perspectively projecting the three-dimensional model 2 according to the determined projection condition, and then the generated image is displayed.
    • 提供三维模型显示程序和三维模型显示装置,其能够实现两点透视投影和三点透视投影之间的无缝切换。 响应于操作输入来确定指示从视点3观看虚拟三维空间的内部的方向的视线矢量。 确定投影条件,当视线矢量接近水平视角矢量时,选择两点透视投影,并且三点透视投影对两点透视投影的影响程度随着增加而增加 视线矢量相对于水平方向的倾斜度。 通过根据确定的投影条件透视投影三维模型2来生成图像,然后显示生成的图像。
