Package org.lwjgl.opengl
Class WGLATIPixelFormatFloat
java.lang.Object
org.lwjgl.opengl.WGLATIPixelFormatFloat
Native bindings to the WGL_ATI_pixel_format_float extension.
This extension adds pixel formats with floating-point RGBA color components.
The size of each float components is specified using the same WGL_RED_BITS_ARB, WGL_GREEN_BITS_ARB, WGL_BLUE_BITS_ARB and WGL_ALPHA_BITS_ARB pixel format attributes that are used for defining the size of fixed-point components. 32 bit floating- point components are in the standard IEEE float format. 16 bit floating-point components have 1 sign bit, 5 exponent bits, and 10 mantissa bits.
In standard OpenGL RGBA color components are normally clamped to the range [0,1]. The color components of a float buffer are clamped to the limits of the range representable by their format.
Requires WGL_ARB_pixel_format
