PassFinder vs Vektoris3D

See the International Space Station as it passes overhead! You'll get that chance by knowing exactly when the ISS is going to pass over your location and is visible to the naked eye.

The well-known solid geometry software Vektoris3D has now been rewritten for learning on iPad and iPhone. Vektoris3D is the app for analytic 3D geometry: for constructing, modifying, exploring, and understanding mathematical models in space. Create points, vectors, lines, planes, surfaces, solids, and measurements in an interactive 3D scene. Change coordinates and variables with sliders and instantly see dependent objects update live. Vektoris3D helps you build models and spatial understanding by connecting mathematical representation, spatial visualization, and construction logic. It shows you not only results, but also relationships, formulas, measurements, and object dependencies. Vektoris3D gives you: - interactive 3D geometry for iPad and iPhone - direct exploration of variables and parameters with sliders - dependency diagrams for traceable construction paths - measurements for distances, angles, areas, and volumes - formula rendering with mathematically precise notation - example and classroom scenes for typical solid geometry topics - an AR view for additional spatial visualization Vektoris3D brings mathematics, model building, and spatial thinking together. This makes mathematical relationships visible, editable, and understandable for you.
