Scrub to pause and inspect. At 0%, B matches A; at 100%, B shows the effect. The scene repeats every 8 seconds.

Look for: 移流と圧力補正を反復 → 煙が流れて広がる。

This model simplifies the technique to show its use case and effect. Operation counts describe the model; they are not performance measurements.

例: 煙の渦

1. Start
密度が一点にある
2. Change
移流と圧力補正を反復
3. Result
煙が流れて広がる

格子上で煙を連続更新できる。時間変化を示す模式図です。実際の描画結果や処理速度を再現したものではありません。

How it works

1. Input
格子上の速度と密度
2. Process
移流・圧力補正を反復
3. Result
流れる煙

A schematic of Stable Fluids / Grid-Based Fluid Simulation. It shows the relationship between input, process, and result; exact values and rendering depend on the implementation.
