Use graphics card acceleration to easily turn your laptop into a heater! _javascript skills

There has been a lot of trouble recently, and I haven’t come here to write about whimsical things for a long time. However, I thought of something very interesting this morning, so I spent half an hour thinking about it briefly and wrote something to share.

When the weather is cold, or when your hands and feet are cold~ So this warm notebook becomes a perfect tool for drying your hands:)

The only drawback is that when I don’t want it to be hot, the fan always keeps spinning. Now I really want to make it warm, but I can’t.

The solution is also very simple. Hang a 3D game there and turn on the special effects. It won’t work even if it’s not hot. However, this takes up a lot of system resources, so it is better to simply create a "heater" yourself!

The hottest hardware in a computer is the CPU and graphics card. Let these two pieces of hardware work non-stop, even if the fans are not spinning wildly~
I originally planned to use vc to write a simple small program that consumes the CPU and GPU, but as a jsfan like me, I will think about any problem: Can it also be implemented on the web? The result is of course positive!
Nowadays browsers support GPU hardware acceleration, why not just use js to implement it~ It can be done with just a few lines of code!

The code is very simple, it just keeps rendering images. After some streamlining, I simply removed the image and replaced it directly with a blank canvas. Anyway, our purpose is not to look beautiful, it is just to make the hardware work and generate heat!

If you want to try it, click here: http://www.etherdream.com/FunnyScript/GPUHeater.html (It is best to use ie9)

Copy code The code is as follows:

Heating...


<script><br>var ctx = document.getElementById('p').getContext('2d');<br>var src = document.getElementById('p2'); <div class="cnblogs_code"> <p>setInterval(function() {<br> for(var i=0; i<1000; i )<BR> ctx.drawImage(src, 0, 0);<BR>}, 16);<BR> </script>

Okay, simple enough code, but it works, The fan started whirring.
On IE9, it runs exactly as expected: the CPU usage is less than 1%, and the page is still rendering even when it is minimized. The specific amount of heat generated has to be decided by the Lu master.
