for my personal work and opengl programming I need cubmaps for reflections. So I have decided to make cubemap generator based on the blender compositor nodes.
With this cubmap generator you can create 6 single images, horizontal and vertical cross images from a 360° panorama equirectangular resp. latitude-longitude format.
Input (only preview, not HDR)
Ouputs (with blur effect)
The Blender project is dynamically configurable:
- Use any equirectangular resp. latitude-longitude format wich blender supports as a texture
- create out textures in power of 2 resolutions (512512, 10241024, other can be addapted)
The naming of the outputfiles is a bit wired, because I have not found an option where I can turn of the frame number naming scheme of the output files. (maybe someone can help here)
When the blender project is opened, then there is a little howto to generate the textures.
This project is created and tested with blender 2.64 RC2.
In the zip archive there are also some gimp projects for the mask and container presets. I don’t have packed a HDRI texture into the archive, instead I have created a JPEG preview from an HDRI, to reduce the size of the archive.
All test images are from http://www.openfootage.net
Comments and critics are welcome
Download current version:
- fix: X axis is mirrored now and correct
- fix: simplifiy and correct the h-cross and v-cross node setup (its now pixel accurate)
- initial release
