Questions tagged [web-applications]

Do NOT use alone. Do NOT use with web-frameworks or libraries like [reactjs], [django] or [flask]. Use for questions about web applications, where a more specific tag isn't applicable. Use with a appropriate language tag([java]) and the specific aspect of web-application, the question is about: http method([post],[get]), errors([http-status-code-404]), client-server communication ([client-server]) or server errors.

A web application is a client-server application that bases the communication on the HTTP () protocol. Often a third layer implements data persistence through a database.

The client side runs in a web browser that sends the http requests, receives the responses, renders the response's content (usually a html page, but also video streams, or applets). The heavy-lifting is done by scripts or compiled code on the server side. Some examples of web applications include Google Calendar (), Zimbra (), and Office Outlook Web Access.

Is there a limit of vertices in WebGL?

Three.js says that it can't load more than 65k vertices. In my pure webgl application, it doesn't say anything, but it doesn't show the entire object when I try big objects. I could split my objects into smaller buffers, but it would make me sad. Is…
