Leer de basisprincipes van geometrisch modelleren met Python. Ontdek hoe je geometrische figuren programmeermatig kunt representeren, manipuleren en benaderen. Deze cursus behandelt basisvormen, transformaties en praktische benaderingstechnieken, waardoor geometrische concepten toegankelijk en interactief worden.

Maak kennis met de kernconcepten van geometrisch modelleren en hoe Python kan worden gebruikt om basisvormen te representeren en te manipuleren.

Verdiep u in geometrische transformaties zoals translatie, rotatie en schaling, en zie hoe deze vormen beïnvloeden in Python.

Leer hoe je krommen en complexe vormen kunt benaderen met behulp van polygonen en andere technieken in Python.

Uitdaging: Translatie
