> ## Name

> texCUBEARRAY - cube array texture lookup with optional pre-computed derivatives.

> ## Synopsis

>     float4 texCUBEARRAY(samplerCUBEARRAY samp, float4 s)
>     float4 texCUBEARRAY(samplerCUBEARRAY samp, float4 s, float3 dx, float3 dy)

>     int4 texCUBEARRAY(isamplerCUBEARRAY samp, float4 s)
>     int4 texCUBEARRAY(isamplerCUBEARRAY samp, float4 s, float3 dx, float3 dy)

>     unsigned int4 texCUBEARRAY(usamplerCUBEARRAY samp, float4 s)
>     unsigned int4 texCUBEARRAY(usamplerCUBEARRAY samp, float4 s, float3 dx, float3 dy)

> ## Parameters

> samp
>   Cube array sampler array to look up.
> s.xyz
>   Coordinates to perform the lookup.
> s.w
>   Cube map array layer.
> dx
>   Pre computed derivative along the x axis.
> dy
>   Pre computed derivative along the y axis.

> ## Description

> Performs a texture lookup in sampler samp using coordinates s, the texture to be sampled is selected from the layer specified in the coordinates. Also may use the derivatives dx and dy.

> ## Profile Support

> texCUBEARRAY is only supported in gp5 and newer profiles.
