三维空间中的坐标轴和坐标平面
探索三维空间中的X、Y、Z坐标轴以及XY、XZ、YZ坐标平面。了解如何使用坐标定位点，并可视化轴与平面之间的关系。
Interactive Coordinate Axes and Planes Visualization
Introduction
Explore fundamental geometric concepts in 3D space. Points represent locations, lines connect points, and planes are flat surfaces. Understand the X, Y, and Z coordinate axes and how they define the 3D coordinate system.
Features:
- Points: Create points in 3D space and see their coordinates
- Line Segments: Connect two points with a finite line segment
- Rays: Draw rays that extend infinitely in one direction
- Lines: Create infinite lines extending in both directions
- Planes: Visualize flat surfaces in XY, XZ, YZ, or custom orientations
- Interactive Controls: Rotate, zoom, and pan to view from different angles
- Labels: Toggle point labels and coordinate axes
How to Use
- Points: Enter X, Y, Z coordinates and click "Add Point"
- Lines: Create at least 2 points, then select line type and choose start/end points from dropdowns (or leave empty to use last 2 points)
- Planes: Select plane orientation (XY, XZ, YZ) or create custom plane with 3 points
- Navigation: Click and drag to rotate, scroll to zoom, right-click and drag to pan
- Selection: Click on a point in the list to highlight it in the 3D view
- Coordinates: Points are positioned at the exact coordinates you specify (X, Y, Z)
