One of HTML5 's most welcome new features is the canvas element, which is responsible for setting an area in the page and then using JavaScript to make a dynamic drawing. Basic usage 　　　id= "Drawing" widht= "Max" height= " > a drawing of Somethind Canvas >After setting the canvas, go to the drawing context, via get. Context ("2d") methodvar drawing = document.getElementById ("drawing"), if (Drawing.getcontext) {var context = Drawing.

Very early plan to learn OpenGL, but because the curriculum and learning algorithms occupy the time, has not been able to start, now this time began to make OpenGL, these days are watching "OpenGL into the 8th edition of the Guide," first read GLSL write shader. Here, try a simple small example with a fixed pipeline, and then start the programmable pipeline.This small example is very simple, is to draw a square in the 2D plane, and then move around.Th

Given a 2D matrix matrix, find the sum of the elements inside the rectangle defined by it upper left corner ( row1, Col1) and lower right corner ( row2, Col2). The above rectangle (with the red border) are defined by (row1, col1) = (2, 1) and (Row2, col2) = (4, 3), which contains Su m = 8.Example:Given matrix = [ [3, 0, 1, 4, 2], [5, 6, 3, 2, 1], [1, 2, 0, 1, 5], [4, 1, 0, 1, 7], [1, 0, 3, 0, 5]] Sumregion (2, 1, 4, 3), 8

The conversion of the 2D is achieved by transform, which has 4 different ways: Displacement: translate (x-coordinate, y-coordinate), which is the displacement from the upper-left corner to the origin, without affecting other elements Scaling: Scale (x multiple, y multiple), which is scaled at the origin of the element center Rotation: Rotate (degrees), which rotates at the origin of the element center.

1. Quartz 2D is a two-dimensional drawing library that closely integrates with the iphone OS to work with all relevant frameworks, including Core Animation, OpenGL es, and Uikit.2. Quartz's drawing function depends on 3 core concepts: Context, path, and state.① Context: The user describes where the graphic is written, and the procedure is defined by Cgcontextref . In general, you can write to UIView or bitmaps. ② Path: The path is something that is of
