The nodejs write nodejs file system module method will come up a lot when it comes to do anything with, well writing a file in nodejs. There is the old way of how to go about using the nodejs write file method that can lead to a kind of call back hell, and then there is the more modern way of using write file that involves the use of promises.
In nodejs the require global is something that will end up being used often in projects as a way to make use of built in as well as custom made nodejs modules. There is more to it then just a way to load modules though, it can also be used as a way to load json files and other assets, so lets take a look at some nodejs require examples today.
In nodejs json is often used as the standard data serialization language of choice for most applications. When it comes to working with json in general in javaScript there is the JSON.parse, and JSON.stringify methods that are of interest. In addition in nodejs there is the nodejs require global that can be used to quickly load json, and the file system module can be used as a built in way to write files including json. There are alternatives to json such as yaml, but for this post I will be going over some of the basics of json in node.js as a way of handing data serialization and config files.
In late releases of Three.js the 2d canvas software renderer has been removed from the core of threejs itself. It is possible to still use it of course it just needs to be added as an additional asset for a project on top of just three js by itself. For the most part these days there is no need to bother with the 2d canvas powered software renderer as the built in webgl renderer will work just fine on most clients, but if for some reason you do want to add more robust support for older clients that do not have great web gl support than the software renderer will have to be added in, and feature testing for web gl will need to be preformed.
In three js there is a built in box helper that can be used to help when it comes to debugging tasks with a mesh, or an Object3d instance. The box can be moved and rotated just like many other objects in three js, and it can also be resized as well. So lets take a look at some quick examples of the box helper in three js.
