OpenLayer's alternative BlitDistorted function actually uses a GL_TRIANGLE_FAN. TranslatorHack 2010, a human translation chain in a.cc. |

Well, do you have a screenshot how it looks in OpenLayer? -- |

How curious, after months of not using it, it doesn't seem to be able to do this as well. TranslatorHack 2010, a human translation chain in a.cc. |

Ok, so we don't want a function that "works like OpenLayer's Bitmap::BlitDistorted" but a new function nobody has ever done yet...? -- |

Seems like too much of a hassle to me. I thought it would be something simple but from the looks of it this is something that is best left to being done in 3D. I retract my request. |

Googling a bit I found this paper from 2004. It sounds like a method to do what you want: http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.62.7170&rep=rep1&type=pdf It requires a hardware implementation though and doesn't seem like any hardware supports it, they all just use triangles. OpenGL ES 1 and 2 as well as normal OpenGL 3 and 4 even removed the GL_QUAD primitives completely. So yes, your best bet is to just use one of the methods suggested in this thread to achieve it, in your own code. -- |

Maybe this case is hard to do?
