How can I display tiles which are diffrent matrix on globe?

[spring]

Hello

  I meet such a problem. My tiles projection is not different from regular, which I mean for example WebGLEarth tiles matrix is square(such as 4x4,8x8 etc), but our projection is different as the tiles matrix is rectangle (such as 4x2,8x4 etc).

  our Y axis is half smaller than the regular Y axis.

 who can help you about this problem?thank you very much
