What fragments are, exactly
Posted: Sun Dec 22, 2024 6:40 am
is not that simple to explain, but we can just think of a fragment as if it was a single pixel on the screen that we’re trying to draw.
As you get more advanced with the whole usa email address data programming graphics rendering pipelines ordeal, you’ll learn that’s not always true, but it’s good enough of a lie for what we’re doing here.
So, a Fragment Shader is a program that will output a color for each pixel of an image.
Fragment Shader – Flutter App Development
Why not just use Dart?
When you write and run Dart code, the compiler transforms your code into machine code. It essentially translates human-readable language into a language that your hardware will understand. And for most cases, that hardware is your CPU.
CPUs are built to be versatile tools for dozens of different use cases. They are fast too, with modern consumer CPUs easily breaking hundreds of GFLOPs (that’s hundreds of billions of operations per second). But that’s not good enough.
See, CPUs are not that great at doing loads of repeatable work at the same time.
Let’s look at a typical screen resolution of 1920×1080, for example. That’s over 2 million pixels that we need to take care of. And ideally, we want to do it 60 times per second. That’s a significant amount of processing power wasted on just updating each pixel on the screen.
We need something better – a GPU.
