NAME¶
packHalf2x16 - convert two 32-bit floating-point quantities to 16-bit quantities
and pack them into a single 32-bit integer
DECLARATION¶
uint packHalf2x16(vec2 v);
PARAMETERS¶
v
Specify a vector of two 32-bit floating point values that
are to be converted to 16-bit representation and packed into the result.
DESCRIPTION¶
packHalf2x16 returns an unsigned integer obtained by converting the
components of a two-component floating-point vector to the 16-bit
floating-point representation found in the OpenGL Specification, and then
packing these two 16-bit integers into a 32-bit unsigned integer. The first
vector component specifies the 16 least-significant bits of the result; the
second component specifies the 16 most-significant bits.
