commands are executed in the app's render thread.Chromium provides an interface called In-process command Buffer GL for the unique GPU command execution of Android WebView (neither executed in a separate GPU process nor executed in a separate GPU thread). As the name implies, in-process command buffer GL is the same as the command buffer GL interface, and the GP

"+ =", for example:recipes += ["Thai Shrimp Cake"]Note that this method is used between arrays. If a single element is to be added to an array, add [] to the element.To retrieve or replace the elements in the array and use the index, this is the same as in OC:?var recipeItem = recipes[0]recipes[1] = "Cupcake"In Swift, Range can be used to indicate the Range: for examplerecipes[1...3] = ["Cheese Cake", "Greek Salad", "Braised Beef Cheeks"]Here, the second to fourth elements in the recipes are re

Surface member function lock to obtain a Canvas, which is essentially a Graphic Buffer to the SurfaceFlinger service Dequeue. Canvas encapsulates the 2D UI rendering interface provided by Skia and is drawn on the previously obtained Graphic Buffer. After the rendering is complete, the Android application process then calls the unlockAndPost request of the Canvas member function obtained above to display it on the screen. In essence, it is a Graphic Buffer to the SurfaceFlinger service Queue, th

Python Learning list NotesThe list is the most frequently used data type in Python;Support for characters, numbers, strings can even contain lists (so-called nesting)1.

greater the Z-buffer value, the farther away. This is the opposite of our normal coordinates (the farther the zcoordinate is, the smaller the zcoordinate is, the negative number ). This is the deep cache. Now, you may remember the code we used to initialize the webgl context from the first lesson: Gl.

projection matrix (Perspective projection matrix). 9. Hide Face Removal WebGL provides a hidden surface removal (hidden surface removal) feature. This feature will help us to eliminate the blocked surfaces (hidden faces), and you can confidently plot the scene without having to estimate the order of the objects in the buffer. Turn on the Hide Face removal feature. You need to follow these two steps: 1. Turn on the Hide Face removal feature Gl.enable (GL
