'''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. The official definition of this extension is available here: http://www.opengl.org/registry/specs/EXT/packed_float.txt ''' from OpenGL import platform, constant, arrays from OpenGL import extensions, wrapper import ctypes from OpenGL.raw.GL import _types, _glgets from OpenGL.raw.GL.EXT.packed_float import * from OpenGL.raw.GL.EXT.packed_float import _EXTENSION_NAME def glInitPackedFloatEXT(): '''Return boolean indicating whether this extension is available''' from OpenGL import extensions return extensions.hasGLExtension( _EXTENSION_NAME ) ### END AUTOGENERATED SECTION
