What’s possible with Taichi
Speed up Python
Taichi translates the compute-intensive Python code into fast machine code at runtime with a just-in-time compiler, accelerating your Python code.
Create an urban airflow simulation using 3D Lattice Boltzmann Method, with spatially sparse data structures provided by Taichi.
A GPU path tracing voxel renderer made by Taichi! You can easily create inspiring voxel art using this renderer within 99 lines of Taichi code.
Computer visionWith automatic parallelization and spatially sparse data structures, Taichi powers the fast development of a LiDAR-based SLAM system.
More Use Cases
The advantages of using Taichi
Easy to learn
No barrier to entry for Python users: Taichi shares almost the same syntax as Python. Apply a single Taichi decorator, and your functions are automatically turned into optimized machine code.
Try drawing a Mandelbrot set in 40 lines of Taichi code
Taichi’s JIT compiler automatically compiles Python functions into fast GPU or CPU machine code for parallel execution. While Taichi lives in Python, it can approach or even outrun the speed of C++ or CUDA.
