OpenGL ES 3.0 stride compressor

This is a command-line tool to change 32-bit IEEE-754 floating-point values to the following formats:

• half-precision floats
• normalized signed and unsigned bytes
• packed INT_2_10_10_10_REV

Usage:

node src/compressor.js strides.bin --stride=FFF-hh-hh-hhh

Stride parameter describes how floats read from source binary files are written to output binary file (which created under /output directory).

Different characters define conversion to different data types:

• F, f - 32-bit float (do not convert)
• H, h - 16-bit half precision float
• B, b - normalized signed byte
• U, u - normalized unsigned byte
• p - 3 floats packed into INT_2_10_10_10_REV
• 0 - adds 1 empty byte to align data
• X, x - skips this value and doesn't add it to output

Any other characters are ignored and can be used for formatting.
