- Understanding how to move objects in 3D space involves setting their coordinates along the x, y, and z axes.
- The x-axis represents horizontal movement, y-axis vertical movement, and z-axis depth.
- Objects can be moved using mathematical functions that define their position over time (parametric equations).
- Example: A cube's x position set to 10 * cos(πt/2) oscillates between 10 and -10 every 2 seconds.
- Combining different functions for x and y positions can create paths like circles or spirals.
- A spiral can be created by making the radius of a circular path grow over time.
- Adding a z component that changes over time introduces depth to the movement.
- Parametric equations allow for creative and complex object paths in 3D space.
- The article demonstrates moving objects from simple circles to complex, mathematically defined paths.
- The project is part of visualrambling.space, with more articles planned on topics like Three.js, WebGL, and 3D mathematics.
