Normal table

Return to forum index

  I'm trying to add kv6 support to my voxel editor, already got kv6 importing figured out but I'm stuck trying to figure out how to generate the normalindex byte from a float normal vector. Is there any simple (slow is OK) formula for that?
  
  Edit: A dump of the table would do the job as well.
  
  Thanks

  Re: Normal table

  In SLAB6.C, search for "equivec". These functions handle the conversion between (x,y,z) and 8-bit normal index. If you just want the list of normals, look at equiind2vec(). The constants, equivec.zmulk and equivec.zaddk, are calculated at the top of equivecinit(), where n is always passed as 255. Good luck.

  Thanks a lot, the equiind2vec() formula did it! I've included credits to you for the vox/kv6 formats on the next version's readme.
