Houdini Main Changelogs

7.0.134

As 16-bit floating point numbers are becoming more common in Houdini, here are some statistics about what a 16 bit float can store:

  • Largest value is 65504.0
  • Smallest non-zero value is around .001

In general a half precision floating point number will yield around 4 digits of precision. For many cases (i.e. texture maps), the advantage of requiring half the memory is a clear advantage.

7.0.134

It's now possible to specify more than just 8 and 16 bit depths for image conversion using iconvert. The -d option takes: -d byte,char,8 = 8 bit unsigned int -d short,16 = 16 bit unsigned int -d half = 16 bit floating point -d float = 32 bit floating point This only works for formats which support the bit depth specified. For example, SGI images don't support half-precision floating point images.
