I've used this function in the past:
TextureChunkPtr createTexture(std::string path)
{
ImagePtr image = Image::create();
beginEditCP(image);
image->read( path.c_str() );
endEditCP(image);
TextureChunkPtr tex1;
tex1 = TextureChunk::create();
beginEditCP(tex1);
tex1->setImage( image );
tex1->setMinFilter( GL_LINEAR_MIPMAP_LINEAR );
tex1->setMagFilter( GL_LINEAR );
tex1->setWrapS( GL_REPEAT );
tex1->setWrapT( GL_REPEAT );
tex1->setEnvMode( GL_REPLACE );
endEditCP(tex1);
return tex1;
}
You might not need all those settings, but try it out.
Hope it helps
Dirk
