Quick Guide =========== This guide will walk you through the basics of **String Cosmo Communication**. Like `Beanim `_, the package for creating Beamer-like slides, we'll start with the available templates and colors, then build a presentation showcasing string theory and cosmology concepts. ---- Available Templates ------------------- String Cosmo comes equipped with nine different templates to homogenize the look of your slides: * 🌅 **cosmic_dawn** - Warm sunrise colors for early universe scenarios * 🌌 **quantum_dusk** - Elegant purple-lavender theme for quantum effects * ⚫ **dark_energy** - Dark theme with bright cyan accents * 🌿 **green_mint** - Fresh mint green theme * 🧊 **blue_ice** - Cool blue color scheme * 🍂 **red_autumn** - Warm autumn colors * 🔵 **beamer_blue** - Classic Beamer style in blue * 🟢 **beamer_green** - Classic Beamer style in green * 🎨 **default_template** - Clean black and white design Template Gallery ^^^^^^^^^^^^^^^^ .. raw:: html

---- Step 1: Import and Setup ------------------------- These templates can be called by importing them at the preamble of your ``file.py`` to work with Manim: .. code-block:: python from manim import * from manim_string_cosmo import * # Choose your template import_template_string_cosmo('cosmic_dawn') class String_Cosmology_Presentation(Scene): def construct(self): # Your presentation code here pass ---- Step 2: Define Your Objects ----------------------------------------- Before building the animation script, define all the objects you'll use. String Cosmo provides specialized objects for visualizing string theory and braneworld scenarios. For example. * **Bubble()** - Vacuum bubble universes with various content types: - ``bubble_type="empty"`` - Empty bubble - ``bubble_type="radiation"`` - Radiation-filled bubble - ``bubble_type="em"`` - Electromagnetic field content - ``bubble_type="strings"`` - String attaching to the brane - ``bubble_type="GW"`` - Gravitational waves * **Black_Hole()** - Higher-dimensional black holes: - ``bh_type="spinning"`` - Rotating 5D black hole from 10D background - ``bh_type="fragmentation"`` - AdS Fragmentation * **AdS_Jc()** - Anti-de Sitter junction configurations: - ``vacua_type="DB"`` - Dark Bubble configuration - ``vacua_type="RS"`` - Randall-Sundrum configuration * **More objects** - To find in the `Documentation ` .. note:: You can define all objects in a separate ``objects.py`` file and import them into your main script for better organization. ---- Step 3: Build Your String Cosmology Presentation ------------------------------------------------- Here's a complete example showing how to create a presentation about bubble nucleation and braneworld scenarios: .. code-block:: python from manim import * from manim_string_cosmo import * from manim_slides import * import_template_string_cosmo('dark_energy') class Bubble_Cosmology_Presentation(Slide): def construct(self): # ============================================ # Object Definition # ============================================ bubble_empty = Bubble(bubble_type="em") bubble_radiation = Bubble(bubble_type="radiation") bubble_strings = Bubble(bubble_type="strings") bubbles = VGroup(bubble_empty, bubble_radiation, bubble_strings)\ .arrange(RIGHT, buff=1).scale_to_fit_width(config.frame_width-1) bh_spinning = Black_Hole(bh_type="spinning") bh_fragment = Black_Hole(bh_type="fragmentation") black_holes = VGroup(bh_spinning, bh_fragment).arrange(RIGHT, buff=10).scale_to_fit_width(config.frame_width-5) ads_db = AdS_Jc(vacua_type="DB") ads_rs = AdS_Jc(vacua_type="RS") ads_configs = VGroup(ads_db, ads_rs)\ .arrange(RIGHT, aligned_edge=DOWN, buff=1)\ .scale_to_fit_width(config. frame_width-1) # ============================================ # SLIDE 1: BUBBLE ANIMATION # ============================================ self.play(AnimationGroup( *[bubble.fade_in_bulk() for bubble in bubbles] )) self.next_slide(loop=True) self.play(AnimationGroup( *[bubble.create_bubble() for bubble in bubbles] )) self.wait() self.next_slide(loop=True) self.play(AnimationGroup( *[bubble.expand_bubble() for bubble in bubbles] )) self.wait() # ============================================ # SLIDE 2: BLACK HOLE ANIMATION # ============================================ self.next_slide(auto_next=True) self.play(FadeOut(bubbles)) self.wait() self.play(FadeIn(black_holes)) self.wait() self.next_slide(loop=True) self.play(AnimationGroup( *[bh.nucleate() for bh in black_holes] )) self.wait() self.next_slide(loop=True) self.play(AnimationGroup( *[bh.expand() for bh in black_holes] )) # ============================================ # SLIDE 3: AdS JUNCTION CONFIGURATIONS # ============================================ self.next_slide(auto_next=True) self.play(FadeOut(black_holes)) self.wait() self.play(AnimationGroup( *[config.fade_in() for config in ads_configs] )) self.next_slide(loop=True) self.play(ads_rs.show_symmetry(rt=3)) self.wait() self.play(ads_rs.restore_symmetry()) self.wait() self.next_slide(loop=True) self.play(AnimationGroup( *[config.fade_in_arrow() for config in ads_configs] )) self.wait() self.play(AnimationGroup( ads_db.show_n_vector_db(rt=3), ads_rs.show_n_vector_rs(rt=3) )) self.wait() self.next_slide() self.play(FadeOut(ads_configs)) Step 4: Render Your Animation ------------------------------ Render the animation using the standard ``manim`` command: .. code-block:: bash manim -pql file_name.py Bubble_Cosmology_Presentation Options: * ``-p`` - Play the video after rendering * ``-ql`` - Quality low (faster rendering for testing) * ``-qh`` - Quality high (for final presentations) For presentations with manim-slides integration, you will need to add ``self.next_slide()`` stops and render as discussed in `Manim Slides documentation `_ .. code-block:: bash manim-slides render file_name.py Bubble_Cosmology_Presentation manim-slides present Bubble_Cosmology_Presentation The final result should look like: .. raw:: html

Next Steps ---------- Now that you've created your first string cosmology animation, explore more advanced features: * 🔧 Learn about all object types and their parameters in the :doc:`api/modules` section * 🎨 Experiment with different templates to match your presentation style * 💡 Create your own sketches and animations to improve this package! .. tip:: **Pro tip:** Start with simple single-object animations to understand the physics, then build up to complex multi-object scenarios. The template system ensures visual consistency across all your animations.
