SectionLab transforms abstract geometry into a hands-on, visual experience. Perfect for students, teachers, and anyone curious about how 2D relates to 3D. BUILD mode — See 2D become 3D Watch flat shapes transform into solid objects through three different mechanisms: • Rotate: Spin a rectangle into a cylinder, a triangle into a cone, or a semicircle into a sphere • Translate: Extrude a circle upward to form a cylinder, or a square into a cube • Roll: Curl a flat plane into a cylindrical surface Drag the progress slider to control how far the transformation goes, or hit Auto Play for a seamless demonstration. CUT mode — Slice 3D shapes to see inside Choose from five geometric solids (cube, cuboid, cylinder, cone, triangular prism) and cut them with an adjustable slicing plane: • Move the cutting plane up/down and tilt it in any direction • Pull the two halves apart to examine the cross-section in detail • Toggle visibility of each half to focus on either side • Use the Cross-Section Dictionary for instant access to classic cuts (circle, ellipse, triangle, hexagon, and more) Why SectionLab? • Fully interactive 3D — pan, rotate, and zoom with touch gestures • No internet required — all 3D rendering runs locally • Multi-language support: English, 中文, 日本語, 한국어 • iPad-optimized with large touch targets • Clean, distraction-free interface designed for focused learning Perfect for: - Middle school and high school geometry students - Teachers looking for classroom demonstration tools - Self-learners exploring spatial reasoning - Anyone curious about the math behind 3D shapes
