Loads Alias|Wavefront .OBJ file format.

Example usage:

cinder::gl::BatchRef myCubeRef;
ObjLoader loader( loadFile( "myPath/cube.obj" ) );
myCubeRef = gl::Batch::create( loader, gl::getStockShader( gl::ShaderDef().color() ) );
myCubeRef->draw();

ObjLoader (std::shared_ptr< IStreamCinder > stream, bool includeNormals=true, bool includeTexCoords=true, bool optimize=true)

Constructs and does the parsing of the file includeNormals
if false texture coordinates will be skipped, which can provide a faster load time
includeTexCoords
if false normals will be skipped, which can provide a faster load time
ObjLoader (DataSourceRef dataSource, bool includeNormals=true, bool includeTexCoords=true, bool optimize=true)

Constructs and does the parsing of the file includeNormals
if false texture coordinates will be skipped, which can provide a faster load time
includeTexCoords
if false normals will be skipped, which can provide a faster load time

void

copyIndicesNonIndexed (uint16_t *dest) const

Builds a sequential list of vertices to simulate an indexed geometry when Source is non-indexed. Assumes dest contains storage for getNumVertices() entries.
void

copyIndicesNonIndexed (uint32_t *dest) const

Builds a sequential list of vertices to simulate an indexed geometry when Source is non-indexed. Assumes dest contains storage for getNumVertices() entries.
