BSplineCtrl B样条空间线
- BSplineCtrl B样条空间线,在空间绘制可以用鼠任意拖动来改变形状的B样条平滑曲线。用到的知识有:B-Spline ,鼠标三维拾取。-BSplineCtrl B-spline space line drawing in space can be used arbitrarily drag mouse to change the shape of B-spline smoothing curves. The knowledge is used : B-Spline, 3D mouse pi
MFC_OpenGL
- 通过等值线的绘制与填充过程分离的编程思想,先用OpenGL硬件加速的光栅化技术实现区域快速填充,然后利用MFC下的GD I绘图功能在相同的区域上绘制等值线。该方法不涉及到复杂的算法,用很简单的代码就能实现与商业软件视觉效果相媲美的等值线填充效果,且适用于离散区域为任意形状的多边形网格系统。
B_
- 1. 用鼠标拖动输入的点做为控制顶点,生成一条B-样条曲线,显示控制顶点和多边形。用鼠标Pick曲线上任意一点,移动鼠标到新位置改变曲线形状。 2. 用鼠标输入一组数据点,插值生成一条B-样条曲线-1 with the mouse to drag the input points as control vertices to generate a B-spline curves, showing the control points and polygons. Pick the curve
3DOpenGL
