Tool Description
Instructions:
- Click the "Add Control Point" button or click on the canvas to add a control point.
- Drag the control point to adjust the curve shape.
- Copy individual or all coordinates in the coordinate table.
- Use preset curves to quickly create common shapes.
- You can copy the generated SVG code and use it in other projects.
Bezier Curve Principle
Bezier curves are parametric curves in computer graphics, defined by control points. They are widely used in vector graphics, such as font design and 3D modeling. An n-th order Bezier curve is defined by n+1 control points and generates a smooth curve through recursive interpolation.
Application Scenarios
- Animation Transitions in UI Design
- Font Design and Vector Graphics
- Motion Trajectories in Game Development
- Curve Modeling in CAD/CAM Systems
- Smooth Curves in Data Visualization
