Algan

---

Algan is designed to be a successor to Manim with full-featured 3-D raytracing capabilities.

As seen on AlgorithmicSimplicity.

Key Features

• Manim Feature Parity: Everything you know and love from Manim.
• GPU Ray Tracing: High-fidelity optical effects including area lights, glossy reflections, refractive glass, soft shadows, and depth of field (path tracer).
• Declarative Timeline Contexts: Intuitive animation staging with Seq(), Sync(), Lag(), Off(), and Speech() blocks makes animation code modular and re-usable.
• Unified 2D/3D Geometry: Seamless morphing and interpolation between 2D Bézier circuits and 3D meshes with become().
• Audio & Speech Alignment: Automatic word-level forced alignment to synchronize on-screen animations with narration.

Installation

pip install algan
algan warmup    # optional: compile the render kernels now, in parallel, instead of during your first render

For installing optional extra features (GPU acceleration, LaTeX for formulas, speech), see the Installation Guide.

Quickstart

Save this script as scene.py:

from algan import *

# 1. Make 3-D objects with physical materials
sphere = Sphere(color=BLUE, radius=1.2)
sphere.set_material(
    MeshPhysicalMaterial(
        roughness=0.15,
        metalness=0.1,
        clearcoat=1.0,
        clearcoat_roughness=0.08,
    )
)

# 2. Define animation timeline with contexts
sphere.spawn()
with Sync(runtime=2):
    sphere.move(RIGHT * 2)
    sphere.rotate(180, OUT, about=ORIGIN)
    sphere.color = RED

# 3. Render video
Scene.save_video("quickstart.mp4")

Run with Python or the Algan CLI:

# Using python
python scene.py

# Using the algan CLI
algan render scene.py

The output video will be written to algan_outputs/quickstart.mp4.
