AI BriefingBuilding Web Animations Without APIs: Interactive Web Development Part 1
Key point
Introduces how to implement interactive web animations without libraries by leveraging principles of mathematics and physics.
Details
Shares a case of developing original interactive web animations by leveraging the laws of mathematics and physics, without relying on libraries.
The snowfall effect utilizes the concept of amplitude and period of a wave. Using the Sine function, the x-coordinate of a snowflake is repeatedly shifted between -1 and 1, and a constant value is added to the y-coordinate to create natural movement.
Linear Interpolation (Lerp) is applied to drawing the tree curve (wire garland). Instead of simply using an API to draw a curve, it's necessary to be able to calculate specific coordinates on the curve in order to place the light bulbs at the exact positions on the curve.
This approach not only builds developers' problem-solving skills, but also greatly helps in gaining a deeper understanding of and making better use of existing libraries.
