ph::TSwizzledTexture< InputT, OutputT, OUTPUT_N > Class Template Reference

Swizzle an array-like input type to the other array-like output type. Output type OutputT can have any number of elements (no need to be the same as input type InputT). For any elements in OutputT that is not part of the swizzle, the value will be as if the element is zero-initialized (or default-initialized depending on the actual type). More...

Detailed Description

template<typename InputT, typename OutputT, std::size_t OUTPUT_N>
class ph::TSwizzledTexture< InputT, OutputT, OUTPUT_N >

Swizzle an array-like input type to the other array-like output type. Output type OutputT can have any number of elements (no need to be the same as input type InputT). For any elements in OutputT that is not part of the swizzle, the value will be as if the element is zero-initialized (or default-initialized depending on the actual type).

Template Parameters

OUTPUT_N

Size of the array-like object. Must not exceed number of elements in OutputT.
