Detailed Description

template<typename D, typename R>
struct MayaFlux::Kinesis::DualField< D, R >

One authored expression carried as both a host callable and shader text.

Template Parameters

D	Domain type.
R	Range type.

The cpu member is an ordinary Tendency and is accepted anywhere a Tendency is, including FieldOperator::bind. It composes with combine, chain, scale, clamp, threshold, invert, lerp and select as any Tendency does. Those free functions build closures, so a composed Tendency has no shader half: composition on the GPU is textual and happens in the kernel body, where several emitted functions are called with whatever arithmetic is wanted.

Field bodies must be authored outside namespace Kinesis. See the authoring rules in ShaderCompat.hpp.

namespace MayaFlux::Fields {
using namespace MayaFlux::ShaderCompat;
 
const auto swirl = MF_FIELD(swirl, [](vec3 p) -> vec3 {
    return cross(vec3(0.0f, 1.0f, 0.0f), p) * 2.0f;
});
}
 
field_op->bind(FieldTarget::POSITION, Fields::swirl.cpu);
