# OpenGL.GL.EXT.packed_float

OpenGL extension EXT.packed_float

This module customises the behaviour of the
OpenGL.raw.GL.EXT.packed_float to provide a more
Python-friendly API

Overview (from the spec)

This extension adds a new 3-component floating-point texture format
that fits within a single 32-bit word. This format stores 5 bits
of biased exponent per component in the same manner as 16-bit
floating-point formats, but rather than 10 mantissa bits, the red,
green, and blue components have 6, 6, and 5 bits respectively.
Each mantissa is assumed to have an implied leading one except in the
denorm exponent case. There is no sign bit so only non-negative
values can be represented. Positive infinity, positive denorms,
and positive NaN values are representable. The value of the fourth
component returned by a texture fetch is always 1.0.

This extension also provides support for rendering into an unsigned
floating-point rendering format with the assumption that the texture
format described above could also be advertised as an unsigned
floating-point format for rendering.

The extension also provides a pixel external format for specifying
packed float values directly.
