rendering

问题 I was wondering what is the best way to implement a renderer in JavaScript. It's not the content part of the rendering that's really important here - I would rather like to hear when and how to effectively run the renderer code. Currently, I have window.setInterval(renderFunc, 1000 / 20) , which will just render a frame each 50 ms (i.e., fps = 20). The point is that faster computers won't render more frames, moreover slower computers will not be able to catch up with 20 fps, so the function

问题 When rendering huge visuals in WPF, the visual gets distorted and more distorted with increasing coordinates. I assume that it has something to do with the floating point data types used in the render pipeline, but I'm not completely sure. Either way, I'm searching for a practical solution to solve the problem. To demonstrate what I'm talking about, I created a sample application which just contains a custom control embedded in a ScrollViewer that draws a sine curve. You can see here that the

问题 I have html in an MS SQL DB. I would like to render the html on a SSRS page, is this possible? 回答1: This kind of capability was deliberately disabled in SQL 2005 Reporting Services because of 'security reasons'. I believe the advice at the time was to record any html as an image and embed the image in the report. I decided to abandon reporting services all together instead. Sorry! If you are using SQL 2008 you can use some HTML in your reports. However, there are some limitations to the

问题 All. A Rails n00b here... I'm writing an application that reports the status of a transaction. Some of the content in the rendered HTML comes from instance variables initialized in the controller, while other content comes from text files (e.g., log files) that I want to render in the HTML using <pre> tags. What is the "Rails Way" to do this? Thank you for your time... 回答1: <pre> <%= render :file => '/tmp/test.log' %> </pre> 回答2: Here you go: http://edgeguides.rubyonrails.org/layouts_and

问题 I have a project which takes a picture of topographic map and makes it a 3D object. When I draw the 3D rectangles of the object, it works very slowly. I read about BSP trees and I didn't really understand it. Can someone please explain how to use BSP in 3D (maybe give an example)? and how to use it in my case, when some mountains in the map cover other parts so I need to organize the rectangles in order to draw them well? 回答1: In n-D a BSP tree is a spatial partitioning data structure that

问题 Problem: Currently, I have a LoginForm component that has an "on-success" handler function handleOnSuccess . This the then linked to the parent component with an onTokenUpdate property defined by a "token-update" handler function handleUpdateToken . The problem is that the setState in the handleUpdateToken function is forcing an undesired rerender. Desired Outcome: What I ultimately need is to update the LoginForm component property token with the value obtained on success WITHOUT performing

问题 I'm using Normalize.css in HTML5 Boilerplate and noticing Firefox 9 on OS X renders fonts differently than every other browser I'm testing with (Chrome 16, Safari 5.1.2, Opera 11.6 all behave the same) Here's some screenshots, no padding or margins: Firefox OS X 9.0.1: Chrome OS X 16: You can see Firefox is rendering the kerning, I believe, larger than the other browsers. Any ideas? 回答1: Fonts do render differently in different browsers. :) 来源： https://stackoverflow.com/questions/8721800

问题 There are lots of widgets provided by sites that are effectively bits of JavaScript that generate HTML through DOM manipulation or document.write() . Rather than slow the browser down even more with additional requests and trust yet another provider to be fast, reliable and not change the widget output, I want to execute* the JavaScript to generate the rendered HTML, and then save that HTML source.­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­­

问题 I have a problem when using Tmux and Vim. As you can see on the picture when I use nerdtree (or irssi, actually any terminal app), I have these kind of rendering problems. Every key I type modify the entire terminal rendering. It's only a graphical bug, but it prevents me from working properly. For example, on the screenshot I submitted, nerdtree is opened. The rendering issue comes mostly when the lines are too long (wrapping) or when I have to scroll (down or up). I haven't found a way to
