Pattern

Pattern は, 各振動子の位相と振幅をデバイスへ送るコマンド. 位相と振幅は別々のバッファで渡す.

API

Rust

Pattern::new(&phases, intensities);

Pattern::with_bank(bank, &phases, intensities);

Pattern {
    bank,
    phases: &phases,
    intensities: intensities.into(),
    transition_mode,
};

Pattern::new は書き込み先バンクを PatternBank::B0 とする. 別バンクへ書く場合は Pattern::with_bank(bank, phases, intensities) を使う.

Python

Pattern(phases, intensities)

Pattern(phases, intensities, bank=bank)

Pattern(
    phases,
    intensities,
    bank=bank,
    transition_mode=transition_mode,
)

Pattern は書き込み先バンクをデフォルトで PatternBank.B0 とする. 別バンクへ書く場合は Pattern(phases, intensities, bank=bank) を使う.

C#

new Pattern(phases, intensities);

new Pattern(bank, phases, intensities);

new Pattern(
    bank: bank,
    phases: phases,
    intensities: intensities,
    transitionMode: transitionMode
);

new Pattern(phases, intensities) は書き込み先バンクを PatternBank.B0 とする. 別バンクへ書く場合は new Pattern(bank, phases, intensities) を使う.

フィールド	型	デフォルト	説明
bank	PatternBank	PatternBank::B0	書き込み先・再生対象のバンク
phases	&[Vec<Phase>]	—	デバイスごとの位相
intensities	PatternIntensity	—	振幅 (Intensity の一様値, または &[Vec<Intensity>] のデバイスごとのバッファ)
transition_mode	TransitionMode	TransitionMode::Immediate	バンク切替時の遷移挙動

patternの計算には幾つかのヘルパ関数が用意されている.

等価な低レベルコマンド

Pattern は WritePatternBuffer + ConfigPattern + ChangePatternBank の 3 つと等価であり, これらは 1 フレームに融合して送られる. 以下は Pattern { bank, phases, intensities } と等価な組み合わせである.

transition_mode に TransitionMode::Later を指定した場合は融合せず, WritePatternBuffer + ConfigPattern の 2 フレームに分解して送る (ChangePatternBank を送らない). 詳細は ChangePatternBank の TransitionMode を参照.

Rust

WritePatternBuffer::new(bank, 0, phases, intensities);
ConfigPattern {
    bank,
    config: SamplingConfig::new(NonZeroU16::MAX),
    size: 1,
    loop_behavior: LoopBehavior::Infinite,
};
ChangePatternBank {
    bank,
    transition_mode,
};

Python

WritePatternBuffer(
    bank=bank,
    index=0,
    phases=phases,
    intensities=intensities,
)
ConfigPattern(
    bank=bank,
    config=SamplingConfig(0xFFFF),
    size=1,
    loop_behavior=LoopBehavior.Infinite,
)
ChangePatternBank(
    bank=bank,
    transition_mode=transition_mode,
)

C#

new WritePatternBuffer(
    bank: bank,
    index: 0,
    phases: phases,
    intensities: intensities
);
new ConfigPattern(
    bank: bank,
    config: new SamplingConfig(ushort.MaxValue),
    size: 1,
    loopBehavior: LoopBehavior.Infinite
);
new ChangePatternBank(
    bank: bank,
    transitionMode: transitionMode
);

Example

Rust

use autd3_rs::commands::Pattern;
use autd3_rs::geometry::{Autd3, Geometry, offset};
use autd3_rs::units::{m, mm, s};
use autd3_rs::value::Intensity;
use autd3_rs::{Client, ClientConfig};
use autd3_rs_link_nop::Nop;
use autd3_rs_pattern::{focus, wavelength};

let geometry = Geometry::new(vec![Autd3::default()]);
let client = Client::open(&geometry, Nop, ClientConfig::default()).await?;

let mut phases = geometry.phase_buffer();
focus(
    &geometry,
    geometry.center() + offset(0.0 * mm, 0.0 * mm, 150.0 * mm),
    wavelength(340.0 * m / s),
    &mut phases,
);

let mut builder = client.datagram_builder();
builder.push(Pattern::new(&phases, Intensity::MAX));
let frames = builder.build()?;
for frame in &frames {
    client.send_checked(frame).await?;
}

client.close().await?;
