  1. From July 7th
  2. .omo animation format listing
  3.  
  4. viz omo format
  5.  
  6. 0x06 - folder call(?)
  7. 0x08 - has an importance
  8. 0x0d - value of 2 for stages and 0 for character animations (possibly tells how many animations types are stored)
  9. 0x0e - bone references
  10. 0x10 - frame count
  11. 0x14 - indicates where index data start
  12. 0x18 - indicates next data start
  13. 0x1a - tells where next block starts
  14. 0x1e - data start
  15. 0x20 - bone entry identification?
  16. 0x30 - start keyframe
  17.  
  18. each bone entry has its own 16 bytes of data at 0x20
  19.  
  20.  
  21. August 18th Update
  22. OMO Data-
  23. Header:
  24. char magic[4] - "OMO "
  25. uint16 unknown[2]
  26. uint32 unknown
  27. uint16 unknown
  28. uint16 channelCount
  29. uint16 frameCount
  30. uint16 frameSize
  31. uint32 channelTableOffset
  32. uint32 fixedDataOffset
  33. uint32 frameDataOffset
  34.  
  35. Channel Table Entries:
  36. uint32 animType
  37. uint32 boneId // matches id in vbn (2 bytes after bone parent index in vbn)
  38. uint32 offsetInFixedData
  39. uint32 offsetInFrame
  40.  
  41. Fixed data size and frame data size for a channel is determined by it's animType - can be empty
  42.  
  43. Types:
  44. Constant - 1x Vector3f (constant on all frames, no frame data)
  45. Interpolated - 2x Vector3f (frame has interpolation value for each coordinate)
  46. There are others I haven't figured out
  47.  
  48. Frame Data:
  49. buffer frameData[frameCount][frameSize]
  50. Channel frame data starts at: frameData[frameNum] + frameDataOffset
  51. Seems to be uint16 interpolation values (i.e. 0x0000-0xffff for 0.0 - 1.0)
  52.  
  53. Eyeballing translation and scale values looks based on this looks sane, I'm not sure about rotation.
  54.  
  55. animType bit field guesses:
  56. 0x04000000 - has scale
  57. 0x02000000 - has rotation
  58. 0x01000000 - has translation
  59. 0x00200000 - translation constant
  60. 0x00080000 - translation interpolated
  61. 0x00007000 - rotation constant
  62. 0x00005000 - rotation interpolated
  63. 0x00000200 - scale constant
  64. 0x00000080 - scale interpolated
  65.  
  66.
