Convert lat long image to cross.

malcolm

Now that hdrshop costs 400 dollars even for a personal license, is there a program that can take an hdr lat long image and convert it into a vertical cross?

Bake a Sphere with spherical mapping to a spherified cube with whichever configuration of crossmap UV's you want...I looked around for an actionscript to do this directly within PS and I am kind of shocked it doesn't exist.

Heres a cube with crossmap UV I already made https://www.dropbox.com/s/u6q239e3m14a6o7/SpherifiedCrossmapCube.obj

edit:
mapped cylinder coords to a flattened cube, works well enough. Much faster to setup and render, The downside would be re-arranging faces.

Thanks guys, but I was hoping for a program that did all the work in one click.

All the low-cost/free ones usually do not do HDR images. I think HDRShop has it locked down as the only stand-alone that can do the conversions...

You can use this and see if it fits your needs:

Then if you like it, just $55 bucks.

I found this as well (mentions Flexify and others)

nvidia's texture tools contain a photoshop script called "cube map shuffler" that can do this. not sure if it works on hdr files, but it's worth a try i guess.

cubemap gen is a standalone app originally developed by ati. i'm pretty sure it supports hdr and so on.
