How do we get texture back from it's ID as image declared by: textureId = glGenTextures(1) This is to save the texture as image or us it any where else on an wxWidget. Thanks |

However, if you're doing pixel transformations or want to get e.g. mip-mapped versions of it then this approach can be useful. HTH, Mike -- ________________________________________________ Mike C.
