hobart

Render polygons, polylines, and mesh cross sections to SVG.

Features

• Render 2D and 3D polygons and polylines to SVG, with automatic computation of the bounding rectangle.
• Render cross sections of lace-style polygonal meshes.

Installation

pip install numpy hobart

Usage

python -m hobart.cli horizontal-xs \
    --reference vitra_with_xs.dae \
    examples/vitra/vitra_without_materials.obj \
