Detailed Description
Wavefront Object exporter The following objects are considered:- VRS::ShapeMaterialGL Materials are written to a mtl-file with the same name as the obj-file.
The opacity-value is taken from the diffuse alpha-channel, the shininess is converted from OpenGL-range (0..128) to obj-range(0..1000)
- VRS::ImageTexture2DGL
- VRS::MipmapTexture2DGL Images are stored as png files. The filenames are created from the obj- filename and an index. For MipmapTexture2DGLs only mip-level 0 is written.
- VRS::PolygonSet Saves vertex-coordinates, per-vertex normals, one set of texture- coordinates and (triangulated) face information. Other per-vertex-data as color, multiple texture-coordinates, fog-coordinates or arbitrary per- vertex-data are not supported by the file-format. Shapes that are repeatedly referenced in the scenegraph are also repeatedly written (taking into account their respective transformation)
- VRS::Transform Transformations are exported directly. Instead, vertices (and normals) are multiplied with the associated matrix (the inverse transpose, resp.) and written to the file.
- VRS::SceneThing Object hierarchies defined by the scenegraph are not preserved. All shapes that are found within the scene are written to the same 'hierarchy level'.

`canHandle' checks whether a concrete writer class can handle a given object or not. `write' will output the object to a file with filename. In the case of i/o errors, an exception of type IOError is thrown. 'write' assumes that the object passed can be handled, i.e., 'canHandle' must return true for that object.

Implements VRS::ObjectWriter.
| virtual const char* VRS::OBJWriter::objectFileSuffix | ( | ) | const [inline, virtual] |
`objectFormatName' gives a verbose description of the file format that is written to. `objectFileSuffix' is the most widely used suffix used for this format.
