float4::float4
Syntax
float4::float4(); [1 line of code]The default constructor does not initialize any members of this class.
This means that the values of the members x, y, z and w are all undefined after creating a new float4 using this default constructor. Remember to assign to them before use.
See Also
Syntax
float4::float4(float x, float y, float z, float w); [11 lines of code]Constructs a new float4 with the value (x, y, z, w).
Note
If you are constructing a float4 from an array of consecutive values, always prefer calling "float4(ptr);" instead of "float4(ptr[0], ptr[1], ptr[2], ptr[3]);" because there is a considerable SIMD performance benefit in the first form.

float4::float4(float x, const float3 &yzw); [9 lines of code]
float4::float4(const float2 &xy, const float2 &zw); [9 lines of code]
Constructs a new float3 with the value (xyz.x, xyz.y, xyz.z, w).

Syntax
float4::float4(const float2 &xy, float z, float w); [9 lines of code]Constructs a new float3 with the value (xy.x, xy.y, z, w).

Syntax
float4::float4(const float *data); [16 lines of code]Constructs this float4 from a C array, to the value (data[0], data[1], data[2], data[3]).
Parameters
const float *dataAn array containing four elements for x, y, z and w. This pointer may not be null.
