OBJFile (Jzy3d API 1.0.0-SNAPSHOT API)

java.lang.Object
- org.jzy3d.io.obj.OBJFile

```
public class OBJFile
extends Object
```
Translated from C++ Version: nvModel.h - Model support class The nvModel class implements an interface for a multipurpose model object. This class is useful for loading and formatting meshes for use by OpenGL. It can compute face normals, tangents, and adjacency information. The class supports the obj file format.

  - loadModelFromFilename
```
public boolean loadModelFromFilename(String file)
```
  - loadModelFromURL
```
public boolean loadModelFromURL(URL fileURL)
```
    This function attempts to determine the type of the filename passed as a parameter. If it understands that file type, it attempts to parse and load the file into its raw data structures. If the file type is recognized and successfully parsed, the function returns true, otherwise it returns false.
  - compileModel
```
public void compileModel()
```
    This function takes the raw model data in the internal structures, and attempts to bring it to a format directly accepted for vertex array style rendering. This means that a unique compiled vertex will exist for each unique combination of position, normal, tex coords, etc that are used in the model. The prim parameter, tells the model what type of index list to compile. By default it compiles a simple triangle mesh with no connectivity.
  - computeBoundingBox
```
public BoundingBox3d computeBoundingBox()
```
    Returns the points defining the axis-aligned bounding box containing the model.
