rendering

问题 Our web analytics package includes detailed information about user's activity within a page, and we show (click/scroll/interaction) visualizations in an overlay atop the web page. Currently this is an IFrame containing a live rendering of the page. Since pages change over time, older data no longer corresponds to the current layout of the page. We would like to run a spider to occasionally take snapshots of the pages, allowing us to maintain a record of interactions with various versions of

问题 I am trying to develop an augmented reality app using swift and scenekit on ios. Is there a way to draw the video captured by the device camera as a background of the scene? 回答1: This worked for me, I used AVFoundation to capture the video input of the device camera: let captureSession = AVCaptureSession() let previewLayer = AVCaptureVideoPreviewLayer(session: captureSession) previewLayer.videoGravity = AVLayerVideoGravityResizeAspectFill if let videoDevice = AVCaptureDevice

问题 Nowadays we have pretty advanced tools to iron out rendering, allowing to see the different stages, time taken by draw calls, etc. But without them the graphics pipeline is quite a black box when it comes to understand what is happening inside. Suppose for some reason you have no such tool, or a very limited one. How would you measure anyway what is taking time in your rendering? I am aware of tricks like discarding draw calls to see the CPU time, setting a 1x1 viewport to see the cost of

问题 This is a duplicate from UI.StackExchange.com: https://ux.stackexchange.com/questions/1004/mixing-percent-and-fixed-css Should you ever apply percentage and fixed CSS together? Will it cause problems, and if so what kinds? Does mixing degrade browser render performance? Will mixing give you weird results on initial load with progressive rendering browsers? Below is just a dumbed-down example of mixed usage, it could be any mixture. I am not looking for validation of the example. I have heard

问题 I am attempting to create a Tetris GUI. My friend wrote the backend. Up until now, we just had the tetris board (or grid as I refer to it in my code) print to the console window. In the code below I am setting up a JTable to act as the board for the Tetris game. I was wondering how I could get my JTable to render each grid element based on the grid passed from the Tetris 'game' declared in the top of the Window class. This grid is a 2D array of integer value which refer to colors enumerated

问题 WPF 4.0 notoriously fixed the blurry text issue. Setting TextOptions.TextFormattingMode="Display" uses pixel hints to line up characters, which works really well to improve clarity. However, it does not work while the program is running as a Windows service in session 0; the text goes back to "Ideal" rendering, which at small sizes is completely unreadable. Below is a comparison of the two renderings. Not running as a service: Running as a service: Rendering code: //rtb is a
