### **Optimized Dynamic AI Prompt for Spiral Galaxy Formation VFX**
This prompt is structured as a comprehensive template. You can adjust the parameters within the `[square brackets]` to dynamically alter the output for a wide range of galaxy formation scenarios.
#### **1. Core Directive & Scene Context**
**`[Render_Style]`** particle simulation showcasing the cosmological formation of a **`[Galaxy_Type]`** spiral galaxy over galactic timescales, visualized as a dynamic, high-fidelity VFX sequence. The scene must accurately depict key astrophysical processes, focusing on gravitational dynamics and stellar evolution within a **`[Dark_Matter_Halo_Presence]`** dark matter halo.
**Primary Goal:** Generate a visually stunning and scientifically plausible particle-based animation or still frame representing a specific moment in a galaxy’s evolution.

#### **2. Subject & Cosmological Process Description**
**A. Central Subject: The Protogalaxy**
The simulation focuses on a massive, rotating cloud of primordial gas (**`[Gas_Composition]`**) and dark matter, undergoing gravitational collapse.
* **Galactic Core / Bulge:** A nascent, high-density central bulge is forming, glowing with the intense light of **`[Core_Star_Density]`** star density and a potential **`[Supermassive_Black_Hole_Seed]`**. The core should exhibit a chaotic yet centrally-bound swarm of particles.
* **Galactic Disk & Spiral Arms:** A flattened accretion disk is forming around the core. Visualize the emergence of spiral arms, not as solid structures, but as **`[Spiral_Arm_Mechanism]`** (e.g., “ephemeral density waves,” “tidally induced filaments,” “stochastic self-propagating star formation”). These arms are the epicenters of **`[Star_Formation_Rate]`** star formation, punctuated by bright, clustered knots of young stars.
* **Galactic Halo:** A vast, spherical, and largely transparent halo of **`[Halo_Composition]`** surrounds the disk. Its presence should be primarily inferred through its gravitational effects on the visible matter, possibly with subtle gravitational lensing artifacts at the edges of the frame.
**B. Key Astrophysical Phenomena to Simulate:**
* **Gravitational Collapse:** Particles should accelerate inward, converting potential energy into kinetic energy and heat. Illustrate the flattening of the rotating system due to the conservation of angular momentum.
* **Accretion & Infall:** Show filaments of intergalactic gas being drawn into the galaxy’s gravitational well, feeding the disk and triggering bursts of star formation as they collide with existing gas.
* **Stellar Feedback:** Depict the impact of newly formed massive stars. This includes powerful stellar winds pushing gas away, and supernova shockwaves creating expanding shells and bubbles (**`[Supernova_Feedback_Intensity]`**) within the spiral arms, which can both compress gas to trigger more star formation and expel it from the disk.

#### **3. Particle System & FX Details**
This simulation is composed of millions of distinct particles, each representing a component of the galaxy.
* **Young, Massive Stars (O/B-type):** Highly emissive, brilliant **`[Young_Star_Color]`** particles. They should be clustered within the spiral arms. Individual particles should have a bright core with a soft, glowing aura.
* **Ionized Gas Clouds (H II Regions):** Volumetric, glowing clouds of **`[H_II_Region_Color]`** gas, illuminated from within by the young stars they contain. These are the most vibrant visual features of the spiral arms. Simulate turbulence and a soft, nebular texture.
* **Neutral Gas and Dust:** Dark, non-emissive, light-absorbing particles that form intricate, wispy silhouettes against the bright nebula and galactic core. These particles should trace the fine, filamentary structure within the spiral arms, creating depth and contrast. Represented as **`[Dust_Lane_Appearance]`**.
* **Older Stars (Disk & Bulge Population):** A dense field of less-bright, **`[Old_Star_Color]`** point-like particles that define the underlying structure of the disk and central bulge.
* **Dark Matter:** Not directly visible. Its influence is key. Represent it as a subtle, pervasive gravitational lensing distortion field or a faint, ghostly swarm of non-interacting particles that dictates the overall rotational velocity and structure of the visible galaxy.

#### **4. Artistic & Cinematic Parameters**
* **Visual Style:** **`[Visual_Style_Keywords]`**. (e.g., “Photorealistic, inspired by Hubble/JWST deep-field images,” “Cinematic documentary style,” “Abstract data visualization”).
* **Color Palette:** **`[Color_Palette_Description]`**. (e.g., “Hubble Palette (SHO): gold, teal, and magenta,” “Naturalistic: brilliant blues, nebular pinks, warm yellows, and deep reds,” “Cool and ethereal: blues, purples, and cyans”).
* **Lighting:** **`[Lighting_Description]`**. (e.g., “High-contrast, dramatic lighting dominated by emissive particles,” “Soft, diffuse light from billions of unresolved stars,” “Volumetric lighting with god rays piercing through dense dust lanes”).
* **Camera & Composition:** **`[Camera_Behavior]`**. (e.g., “Epic wide-angle establishing shot, static,” “Slow, majestic orbital pan around the galactic plane,” “Dynamic camera fly-through of a spiral arm,” “Tilted, top-down ‘god’s eye’ view”).
* **Atmosphere & Mood:** **`[Atmosphere_Keywords]`**. (e.g., “Awe-inspiring, immense scale, cosmic ballet,” “Violent, chaotic, energetic,” “Serene, majestic, ancient”).

#### **5. Technical Specifications & Output Control**
* **Rendering Engine Style:** `Unreal Engine 5 cinematic render`, `Octane Render`, `Houdini particle fluid simulation`, `ray tracing`, `path-traced global illumination`.
* **Detail Level:** `8K resolution`, `hyper-detailed`, `intricate filamentary structures`, `astronomical precision`, `no aliasing`.
* **Negative Prompts (What to Avoid):** `2D flat image`, `cartoony`, `blurry`, `low-resolution`, `uniform particle distribution`, `static`, `no motion`, `obvious digital artifacts`, `hard edges`, `lack of depth`.

### **Example Prompt in Practice**
Here is a concrete example using the dynamic template above to generate a specific scene.
**(1. Core Directive)**
`Cinematic render` particle simulation showcasing the cosmological formation of a `large barred spiral galaxy (SBc type)` over galactic timescales, visualized as a dynamic, high-fidelity VFX sequence. The scene must accurately depict key astrophysical processes, focusing on gravitational dynamics and stellar evolution within a `dominant, massive` dark matter halo.
**(2. Subject & Cosmological Process)**
The simulation focuses on a massive, rotating cloud of primordial `hydrogen and helium gas with trace heavy elements` and dark matter, undergoing gravitational collapse.
* **Galactic Core / Bulge:** A nascent, high-density central bar is forming, glowing with the intense light of `extremely high` star density and a `bright, active quasar-like seed`.
* **Galactic Disk & Spiral Arms:** A flattened accretion disk is forming around the central bar. Visualize the emergence of spiral arms as `ephemeral density waves`, which are triggering a `high, bursty` star formation rate. These arms are punctuated by bright, clustered knots of young stars.
* **Galactic Halo:** A vast, spherical halo of `globular clusters and sparse primordial stars` surrounds the disk, its presence inferred through subtle gravitational lensing artifacts at the edges of the frame.
* **Astrophysical Phenomena:** Emphasize gravitational collapse leading to disk flattening. Show filaments of intergalactic gas being accreted along the dark matter web. Depict `intense` supernova feedback, creating visible expanding superbubbles of hot gas that blow out of the disk in a “galactic fountain” effect.
