Class ARBHalfFloatPixel


  • public final class ARBHalfFloatPixel
extends java.lang.Object
    Native bindings to the ARB_half_float_pixel extension.

    This extension introduces a new data type for half-precision (16-bit) floating-point quantities. The floating-point format is very similar to the IEEE single-precision floating-point standard, except that it has only 5 exponent bits and 10 mantissa bits. Half-precision floats are smaller than full precision floats and provide a larger dynamic range than similarly sized normalized scalar data types.

    This extension allows applications to use half-precision floating-point data when specifying pixel data. It extends the existing image specification commands to accept the new data type.

    Floating-point data is clamped to [0, 1] at various places in the GL unless clamping is disabled with the ARB_color_buffer_float extension.

    Requires OpenGL 1.5. Promoted to core in OpenGL 3.0.
