graph visualization

This two-part article series will demonstrate a visualization technique that helps extract information from the data that has business value, and this article is the first part of the series. You'll see how to use Scalable Vector Graphics (SVG) and open source D3 JavaScript libraries to create visual representations that can be viewed through the browser, conveying information through shapes and colors. I'll demonstrate these techniques with some exam

Abstract : Visualization of Large Scale Terrain with huge textures is a very active filed at present. there is a bottleneck between the complexity of the scene and the capability of current system. therefore special algorithms have to be adopt to deal with this problem. usually, these algorithms try to give a multi-resolution representation of the terrain, then use a view-dependent triangle mesh to render the scene. incluefforts have been focused on

OData (Open Data Protocol) is always a standard I like (OASIS Standard), which provides a powerful access interface for querying and editing data based on restful protocols (Protocol). Although Microsoft launched it, it was born with open standards and open source genes (the first Microsoft opened the code for the OData client). When I have a chance, I'll go over some of the knowledge of OData in more detail.Previously, the OData development experience I was involved in was mostly focused on acc
