Functions

GLM_FUNC_DECL double packDouble2x32 (uvec2 const &v)
 Returns a double-qualifier value obtained by packing the components of v into a 64-bit value. More...
 
GLM_FUNC_DECL uint packHalf2x16 (vec2 const &v)
 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. More...
 
GLM_FUNC_DECL uint packSnorm2x16 (vec2 const &v)
 First, converts each component of the normalized floating-point value v into 8- or 16-bit integer values. More...
 
GLM_FUNC_DECL uint packSnorm4x8 (vec4 const &v)
 First, converts each component of the normalized floating-point value v into 8- or 16-bit integer values. More...
 
GLM_FUNC_DECL uint packUnorm2x16 (vec2 const &v)
 First, converts each component of the normalized floating-point value v into 8- or 16-bit integer values. More...
 
GLM_FUNC_DECL uint packUnorm4x8 (vec4 const &v)
 First, converts each component of the normalized floating-point value v into 8- or 16-bit integer values. More...
 
GLM_FUNC_DECL uvec2 unpackDouble2x32 (double v)
 Returns a two-component unsigned integer vector representation of v. More...
 
GLM_FUNC_DECL vec2 unpackHalf2x16 (uint v)
 Returns a two-component floating-point vector with components obtained by unpacking a 32-bit unsigned integer into a pair of 16-bit values, interpreting those values as 16-bit floating-point numbers according to the OpenGL Specification, and converting them to 32-bit floating-point values. More...
 
GLM_FUNC_DECL vec2 unpackSnorm2x16 (uint p)
 First, unpacks a single 32-bit unsigned integer p into a pair of 16-bit unsigned integers, four 8-bit unsigned integers, or four 8-bit signed integers. More...
 
GLM_FUNC_DECL vec4 unpackSnorm4x8 (uint p)
 First, unpacks a single 32-bit unsigned integer p into a pair of 16-bit unsigned integers, four 8-bit unsigned integers, or four 8-bit signed integers. More...
 
GLM_FUNC_DECL vec2 unpackUnorm2x16 (uint p)
 First, unpacks a single 32-bit unsigned integer p into a pair of 16-bit unsigned integers, four 8-bit unsigned integers, or four 8-bit signed integers. More...
 
GLM_FUNC_DECL vec4 unpackUnorm4x8 (uint p)
 First, unpacks a single 32-bit unsigned integer p into a pair of 16-bit unsigned integers, four 8-bit unsigned integers, or four 8-bit signed integers. More...
