Detailed Description

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

An authored expression of position, time and a parameter block, shader-only.

Template Parameters

D	Domain type.
R	Range type.

Carries no Tendency, for the same reason TemporalField does not. The third argument is a vec4 supplied by whoever dispatches the shader, and it is what lets a field depend on state the shader text cannot hold, such as an Agent's position and radius. For GpuFieldOperator it is set with set_params() and pushed every dispatch, so changing it recompiles nothing.

namespace MayaFlux::Fields {
using namespace MayaFlux::ShaderCompat;
 
const auto pull = MF_FIELD_P(pull, [](vec3 p, float t, vec4 a) -> vec3 {
    vec3 d = vec3(a.x, a.y, a.z) - p;
    float r = length(d);
    return r > 0.001f ? (d / r) * (a.w / (r * r + 0.1f)) : vec3(0.0f);
});
}
