What is the ideal framerate for smooth animation?

I'm looking to add a snow animation using JavaScript. I currently have it running at 200ms which is decent but not smooth enough. Would changing the interval to 20ms make it more fluid, or would it be inefficient and strain the CPU?

window.setInterval(snow.draw, 20);

Check out an example here

snow = {
count: 60,
delay: 20,
flutter: 0.2,
wind: 1.0,
w1: 1,
minSpeed: 0.3,
maxSpeed: 4,
cv: null,
flakes: [],
toggle: function() {
    if(window.snowtimer)
        snow.stop();
    else
        snow.start();
},
resize: function() {
    snow.cv.width = innerWidth;
    snow.cv.height = innerHeight;
    snow.gt = snow.ct.createLinearGradient(0,0,0,snow.cv.height);
    snow.gt.addColorStop(0.0, '#6666ff');
    snow.gt.addColorStop(1.0, '#ffffff');
    snow.ct.fillStyle = snow.gt;
},

// Additional functions go here...

};

Answer №1

When it comes to snow effects, 20ms may be too fast and 50FPS might be excessive. The typical eye can perceive around 20fps, but 25fps is recommended if you want to optimize processing.

To achieve good quality, aim for 30FPS or higher.

In conclusion, consider setting it to 30ms. This will allow the graphics to render close to the speed of the human eye. Experiment with 40ms (25fps) to potentially save on processes without compromising the visual effect.

Answer №2

In my opinion, 30 frames per second seems like a reasonable benchmark. Traditional film stock typically operates at approximately 24fps, whereas most contemporary video games aim for around 30fps (or even 60fps with more advanced graphics cards).

On average, the human eye can process about 20 frames per second, although this rate can increase to 60fps during moments of heightened survival instincts or panic.

Calculating at 1000/30ms results in a slightly higher than 30fps output.

Answer №3

Most people can perceive around 24-30 frames per second, with web animations typically running at 15 fps and high quality movies at 30 fps. TV animation usually operates at around 24 fps.

Therefore, when setting the interval for your animation in JavaScript, it's important to consider the frame rate. It's recommended to stick close to industry standards for a smooth viewing experience.

window.setInterval(snow.draw,your choice);

Experimenting with higher refresh rates, such as 48 fps with repeated frames, is an option if you're not satisfied with the default settings.

Optimizing performance is crucial, especially on web browsers with varying resources. Minimizing unnecessary processes can greatly improve the fluidity of animations. Consider combining elements to reduce load.

Wikipedia provides valuable insight on frame rates, mentioning that the human visual system can process 10 to 12 images per second individually.

Additionally, film and video creators often use 24 frames per second for its cinematic "look," even when not transferring to film directly.

Answer №4

In order for an animation to appear fluid and seamless, it is crucial that the frame rate remains consistent. To achieve this on a computer, the frame rate must be a whole divisor of the monitor's refresh rate. For instance, with the common 60Hz monitors today, ideal frame rates include 60FPS, 30FPS, 15FPS, etc.

While most individuals can distinguish individual frames at a 15FPS frame rate, some are able to do so at 30FPS. It is recommended to aim for a 60FPS (16ms) frame rate if possible, particularly for fast-moving animations, but settling for 30FPS (33ms) is acceptable if drawing speed is limited.
