Lecture Description:
Canvas vs. SVG Performance in Interactive Animation
In this lesson, we will compare the performance of canvas and SVG in creating interactive animations. The example animation we'll work on may be familiar if you've taken the "Interactive Web Animation" course, which previously used SVG. Now, we will implement the same animation using canvas and evaluate the results.
Key Concepts:
Setup:
The animation consists of HTML and JavaScript files.
The HTML file will feature a full-screen canvas element with a black background and no scrollbars.
The canvas element will have an ID of "canvas1".
Object Style Implementation:
The animation properties include node count, node radii for depth effect, screen dimensions, and displacement calculations.
Nodes will be circles whose sizes and positions react to the mouse cursor, creating an interactive surface.
Canvas Drawing:
Nodes will be drawn using the Path2D interface and the arc() method.
Each node's position and size will change based on the cursor's location, calculated using the Pythagorean theorem.
Interactive Features:
The animation will update in response to the mouse position, recalculating node positions and radii dynamically.
A small configurator will allow customization of the animation's appearance via keyboard input.
Performance Comparison:
Initially, both canvas and SVG will perform similarly with a small number of nodes.
As the number of nodes increases, canvas demonstrates superior performance with quicker initialization and smoother animation.
Final Thoughts:
We will conclude by discussing the results and determining which technology offers better performance for complex, interactive animations. Through practical experimentation and customization, you'll gain a deeper understanding of the strengths and limitations of both canvas and SVG.
