Loading obj files in java 3d

Step 2 is probably going to be different as well, because you may already have data structures to save all of that data, or you may want them to be in a certain way to be efficient, or whatever. Which is why I structured the oObjLoader the way I did. In fact usually people define their own "internal" file formats that are quicker to load and parse, and may contain additional information they need. You should look at loading.

OBJ files as more of a process of importing them into your system. The oObjLoader provides you with a parser that does phase 1. The Parser sends all of that to phase 2 by callings methods defined in the Builder interface. I named it Builder because I couldn't think of a better name. In other words, it defines a bunch of method calls, but not the actual code.

The Builder interface maps very closely to the actual. OBJ file format, each call more or less just takes one element that we've parsed from the. OBJ or. MTL file. It has a bunch of method definitions.

But since it's an interface, it doesnt' actually have the code for the method bodies, just the definition. The parser takes care of turning everything from ASCII into floats or whatever, and knows what Builder method to call based on what everything is.

But it's pretty straight forward. It does things in somewhat wasteful ways, it is probably wrong for you and definitely not nearly as efficient as it could be. On the other hand, hey, it works, so you can use it to play with. OBJ files right away. Note, while oOblLoader will fully parse the. In fact really it just uses the default OpenGL lighting and the texture image file, if any, specified in the.

The implementation is backed up by a sufficient number of tests. The library has no runtime dependencies so it should be fairly easy to integrate into your project. It is built via Maven so it will be easy to integrate in Maven projects. You will need to manually register it in your local repository. If your project is not a Maven one - don't worry, it should not be a problem. Stack Overflow for Teams — Collaborate and share knowledge with a private group.

Thanks -Will. You will probably be better off rolling your own if you don't like the parser in the Java3D libraries. If you don't mind embedded rendering then take a look at pixelnerve.
