NASA WORLD WIND VS CESIUM CODE
Since it is intended as a learning aid, the code is written in a style that we hope is easy to understand and follow, especially when accompanied by the book.įor information on getting up and running with the code on both Windows and Linux, see the instructions here.Help translate this site by visiting Community The code (and the book) draw from the authors' real-world experience working on STK, one of the earliest commercial virtual globes.
NASA WORLD WIND VS CESIUM PATCH
Terrain patch rendering using CPU triangulation, GPU displacement mapping, and GPU ray casting.Vector data rendering, including reading vector data from shapefiles.High-precision vertex rendering techniques to avoid jittering problems.
Techniques for avoiding depth buffer errors when rendered objects are found at widely varying distances from the camera.WGS84 (and other ellipsoid) globe rendering using tessellation or GPU ray casting.A well designed (and pragmatic) renderer abstraction making it easier and less error prone to interface with OpenGL.OpenGlobe has the following features and capabilities: It is not a complete virtual globe application, but is rather a core engine and a number of runnable examples.
NASA WORLD WIND VS CESIUM FULL
It is written in C# (with full support for running on Linux using Mono) and uses the OpenGL 3.3 core profile via OpenTK. OpenGlobe is a 3D engine for virtual globes (think Google Earth or NASA World Wind) designed to illustrate the engine design and rendering techniques described in our book, 3D Engine Design for Virtual Globes. But for a production quality, open source, virtual globe by the same authors (plus more), check out Cesium! Note: OpenGlobe is great for learning along with our book, 3D Engine Design for Virtual Globes.
