Description
Explore how 3D shapes overlap and intersect. This exercise shows the exact intersection volume between shapes, helping you understand spatial relationships and form.
How to Use
- Click and drag on the shapes above to rotate the view
- Click the 🎲 button to randomize the shapes
- Switch levels using the buttons above
- Observe the coral intersection volumes where shapes overlap
Level 1 — Two Shapes
Two shapes with contrasting pastel colors. Simple overlap to study basic spatial relationships.
Level 2 — Three Shapes
Three pre-rotated shapes arranged in a triangle. More complex overlap patterns with multiple intersection zones.
Available Shapes
The sketch randomly selects from these 3D primitives:
- Box — rectangular prism
- Sphere — perfect round shape
- Cylinder — tube with flat ends
- Cone — pointed top, flat base
- Torus — donut shape
Practice Tips
- Try to predict what the intersection will look like before randomizing
- Notice which shape combinations produce the most complex intersections
- Use this as a reference when drawing overlapping forms in perspective
- In Level 2, observe how three-way overlaps form when all shapes intersect
