Crank up the number of dots and see how j Query, GSAP, and Zepto compare.Since Zepto uses CSS transitions for all of its animations, it should perform best, right?For example, what if you want to animate "rotation" and "scale" independently, with different timings and eases?Maybe an element is continuously pulsing (oscillating scale) and you'd like to rotate it on rollover. See the Pen Independent Transforms by Green Sock (@Green Sock) on Code Pen In my opinion, this is a glaring weakness in CSS but if you only do simpler animations that animate the entire transform state at any given time, this won't be an issue for you.“Gnomon is the best school for 3D art and I’m so glad I attended.The classes are challenging but absolutely worth the commitment.
The most frequently cited reason for using CSS for animation is "hardware acceleration". Let's break it down into two parts: The GPU is highly optimized for tasks like moving pixels around and applying transform matrices and opacity, so modern browsers try to offload those tasks from the CPU to the GPU.
I went from having zero 3D experience to being hired immediately after graduation. ”“Gnomon was crucial in my success in the video game industry.
Being exposed to constant creativity, inspiration, and critique was extremely helpful for my transition into game development on the artist side of things.”“Attending Gnomon was the best career choice I ever made.
The secret is to isolate the animated elements onto their own GPU layers because once a layer is created (as long as its native pixels don't change), it's trivial for the GPU to move those pixels around and composite them together.
Instead of calculating every single pixel 60 times per second, it can save chunks of pixels (as layers) and just say "move that chunk 10 pixels over and 5 pixels down" (or whatever).
