合成景观360度

Question

有没有人对SRTM或HGT或DEM文件（“数字海拔数据”）有经验，可以与您创建图像类型的静态和合成景观： http : //www.lalpinistavirtuale.it/Panorami/Ronce_sintetico.jpg I想讨论一下（算法，绘图模式等。）谢谢您提供任何信息

Answer 1

Given elevation data, ie a height map, you can generate a 3D mesh made of triangles. This is a technique commonly used in video game development, and you should have no problem finding sample code for doing so online (one place you could look is in the terrain generators of the Irrlicht or OGRE graphics engines).

You could then use Android's OpenGL support to render these meshes into a virtual landscape like the one you linked.

You could then just move the virtual camera around your generated world. Or, if you want to generate a panorama, just keep the camera in one location, then rotate around, rendering images. Since you know the azimuth at which you rendered each image, combining them should be fairly trivial.
