anicg 12 Posted February 16 attached is a wonderful file from cigiwiki: https://www.tokeru.com/cgwiki/index.php?title=HoudiniCops Where it converts a latlong into a cubemap, kind of unwraps an 360degree image. The problem is I'm stuck with the cubemap and want to go back to latlong. Any idea how to invert the code? Latlong_to_cubemap_v04.hipnc Share this post Link to post Share on other sites
sebkaine 286 Posted February 19 (edited) i dont't have a direct answer to your question but houdini has a command line utility call isixpack that allow cube to lat and lat to cube conversion : whatever you do in houdini or vex you will get decent quality but distorsion at the nadir/pole. the best library for doing this kind of work is krpano, almost every HDRI map manipulation tool use this library. it gives great result in term of distorison and blurring. https://krpano.com/home/ For the hard way , this is one of the best place to start : http://paulbourke.net/panorama/cubemaps/ https://github.com/madwyn/libcube2cyl/blob/master/src/Cube2Cyl.hpp Edited February 19 by sebkaine Share this post Link to post Share on other sites
