SIMD.%type%.swizzle()
This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.
The static SIMD.%type%.swizzle() method creates a new SIMD data type instance with the lane values swizzled (re-ordered).
Syntax
SIMD.Float32x4.swizzle(t, s0, s1, s2, s3) SIMD.Float64x2.swizzle(t, s0, s1) SIMD.Int8x16.swizzle(t,s0,s1,s2,s3,s4,s5,s6,s7,s8,s9,s10,s11,s12,s13,s14,s15) SIMD.Int16x8.swizzle(t, s0, s1, s2, s3, s4, s5, s6, s7) SIMD.Int32x4.swizzle(t, s0, s1, s2, s3) SIMD.Uint8x16.swizzle(t,s0,s1,s2,s3,s4,s5,s6,s7,s8,s9,s10,s11,s12,s13,s14,s15) SIMD.Uint16x8.swizzle(t, s0, s1, s2, s3, s4, s5, s6, s7) SIMD.Uint32x4.swizzle(t, s0, s1, s2, s3)
Parameters
- t
- An instance of a SIMD type to be swizzled / re-ordered.
s0-s15- index in t for lanes s0-s15.
Return value
A new SIMD data type with the lane values swizzled (re-ordered).
Description
The static SIMD.%type%.swizzle() method can be used to re-order a SIMD data type.
Examples
Swizzling a Float32x4
var t = SIMD.Float32x4(1, 2, 3, 4); SIMD.Float32x4.swizzle(t, 1, 2, 0, 3); // Float32x4[2,3,1,4]
