图形透视投影变换
- 显示三维图形的过程中,不仅要将它投影到二维平面上,还要确定一个视见体,在投影之前对物体进行裁剪,只显示我们感兴趣的那部分图形。-show 3D process, it should not only two-dimensional projection of the plane, but also to determine see as a body, the projector right before cutting objects, only shows that we are inter

- 二维和三维图形的基本变换 二维填充:二维填充有三种算法,其中有序边扫描线转换算法是固定填充的,四连通和扫描线种子填充法是可以填充任意形状的图形(曲线,多边形等)的,并且还可以判断种子点为外部点还是内部点。在使用时只需先画好需要填充的边界然后选择种子填充并用鼠标左键点击确定种子点即可填充。 二维裁剪:二维裁剪是演示性的功能,直接点击该菜单项就可以演示了。 二维基本变换:二维基本变换是演示性的功能,直接点击该菜单项就可以演示了。 二维动画:二维动画是演示性的功

- 三维重建,根据相机的内参数进行旋转变化可以将三维点映射变换到二维图像中去-Reconstruction, based on the changes in the parameters of the camera can be rotated transformed into a three-dimensional map points to the two-dimensional image
2d-3d
- 通过代码实现二维,三维图形的变换,包括 平移,旋转,对称等,并有转换后的基本坐标-Through code 2 d, 3 d graphics transformation, including translation, rotation, symmetry and so on, and have basic coordinates after conversion
D2FFT
- 二维傅里叶变换,是求解3D图像中重要图像处理步骤,也可转到一维之后再按照一维的规则进行编码-After the two-dimensional Fourier transform, the 3D image is to solve an important image processing step can also go further in accordance with a one-dimensional one-dimensional coding rules
