当从外界读入STL等三维模型时,其会按照它内部的坐标位置进行显示.因此它的位置和大小是确定的.但是在实际应用中,有可能需要人为地对这个模型在空间中进行旋转.平移或缩放等操作.VTK中有许多和旋转.平移相关的函数,下面一一进行测试. RotateX.RotateY.RotateZ(绕自身坐标轴旋转) Rotate the Prop3D in degrees about the X/Y/Z axis using the right hand rule. The axis is the Prop3D'
基本功能实现:物体通过鼠标左键上下移动,中间键缩放.右键旋转,30秒没操作,物体自动旋转 实例代码: using UnityEngine; using System.Collections; public class Script_07_11 : MonoBehaviour { public Transform target; private int MouseWheelSensitivity = 50; private int MouseZoomMin = 20; private int Mo
原地址:http://game.ceeger.com/Manual/HOWTO-FixZAxisIsUp.html Some 3D art packages export their models so that the z-axis faces upward. Most of the standard scripts in Unity assume that the y-axis represents up in your 3D world. It is usually easier to f
0 引言 在利用PCL的交互功能解决尺寸关联几何的指定问题时,涉及到一些显示上的操作.目前的需求是:将投影到注释平面上的点云,以与屏幕平齐的方式,显示在屏幕正中,这样方便用户进行操作.但是,在运用setCameraPosition 对点云视图进行设置时,由于不了解参数意义,所以无法达到目的. setCameraPosition 的API如下所示. /** \brief Set the camera pose given by position, viewpoint and up vector *
