the implementation of the first edition demo involves three parts: 1. Draw lines and add physical events(1) Get mouse input(2) Convert to screen coordinates, then set to Linerender to draw(3) Create a collider based on the information of the mouse input point2. Handling of objects and obstacles(1) Create objects and obstacles, add rigid bodies, and match the relevant collider(2) To configure the relevant parameters such as gravity(3) using the PHYSIC2D collision parameters, add the corresponding

First, the foreword: The Delphi method is basically the same as the point of drawing. The difference is in the Glbegin () parameter. the frame code drawn can refer to the code in opengl2d drawing initialization under Delphi, and the address is http://www.jb51.net/article/52141.htm. The modified part is the content of the Draw function. Second, draw the line ste

1. Use Matlab as a closed polygon drawing Instead of finding a function that directly draws a polygon, you can only save the coordinates of each point in an array, connect a point to its adjacent point, and attach the last point to the first point. The following is an example of the. m File: Copy Code code as follows: Clear CLC A=[0 2 4 6 8 10 12 14;0 2 1 4 6 6 5 7]; % the point coordinates to be connected x;y [N,m]=size (a);

For the agg font for a very simple introduction, the following is a simple description of the agg line. first for drawing lines, there are several lines such as ordinary lines, actual lines, lattice-like lines. Agg is supported for each line. In addition to the beginning of the line of the end of the style there are s

This article mainly implements the Java drag mouse draw line function, in order to achieve the function of drawing line, respectively with implements MouseListener and Mousemotionlistener, and by mousepressed (), mousereleased () Gets the start and end coordinates of the mouse drag. This is a good example of mastering Java mouse events. The specific implementati

Draw_point (x0, y0, color); is a painting point function I wrote. You don't need to worry about it. The key is the painting line algorithm. /* Draw line functionThis algorithm is an optimization algorithm for bresenham's line-drawing algorithm. It removes multiplication and division operations to make the operation fas

Comments: Drawing an ellipse in a Canvas is a common requirement, but this method has not been implemented in most browsers currently. Therefore, the arc or arcTo method is often used to draw an ellipse in combination with scale deformation, if you are interested, you can understand it and hope it can help you. Drawing an ellipse in a Canvas is a common requirement. The ellipse method is added to the new HT

In Android, when there is a need to draw a line chart, most people use the achartengine to draw a line chart. The Achartengine Chart engine does have the ability to implement a line chart, and in addition to this, we can use the chart module inside the Andbase development framework to make the icon drawing. The previou

As shown in the picture, each five-second diagram will be moved once (in fact, a redraw of the picture) to display the monitored CPU information. The Pastcpuinfomation function is mainly used to display a line chart The Updatecpupic function removes the figure 5 seconds ago and then draws a picture from the existing data. The Updatecpuinfomation function adds the newest point to the array that stores the polyline Then in the interface to get two t

Drawing an ellipse in a Canvas is a common requirement, but most browsers have not yet implemented this method. Therefore, the arc or arcTo method is often used in combination with scale deformation to draw an ellipse, if you are interested, you can understand and hope to help you draw an ellipse in your Canvas, comparing the new HTML Canvas 2D Context W3C draft, the ellipse method is added to draw an ellipse, but this method has not been implemented
