Algan
Full-featured 2D/3D programmatic animation engine for explanatory mathematics and technical videos.
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 depth of field, area lights, glossy reflections, refractive glass, and soft shadows.
- Declarative Timeline Contexts: Intuitive animation staging with
Seq(),Sync(),Lag(),Off(), andSpeech()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
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.
