rendering

问题 I have a customized vertical scrollbar which displays markers for selected items in a DataGrid. The problem I'm facing is, when there are a great number of items (e.g. could be 5000 to 50000) there is a lag while it is rendering the markers. With the following code it basically renders as per the selected items index, number of items and height of the track. Obviously this is inefficient and am looking for other solutions. This is my customized vertical scrollbar <helpers

问题 Am using three.js How can I control the rendering order? Let's say I have three plane geometries, and want to render them in a specific order regardless of their spatial position. thanks 回答1: You can set renderer.sortObjects = false; and the objects will be rendered in the order they were added to the scene. Alternatively, you can leave sortObjects as true , the default, and specify for each object a value for object.renderOrder . For more detail, see Transparent objects in Threejs Another

问题 I have created a new project and after build is done, when I tried opening activity_main.xml it is giving me following Rendering error: Can anyone tell, what's the possible reason behind this and how to solve this problem? I have just started learning android , but in the very beginning I am getting stuck. As asked, adding my app's build.gradle and layout.xml : Build.gradle: apply plugin: 'com.android.application' android { compileSdkVersion 27 buildToolsVersion "28.0.0" defaultConfig {

问题 I have to draw my shapes on a offscreen bitmap, but I have a strange problem when I try to render my bitmap. This is how the image should be displayed: And this how I a see the bitmap: Following is the code I use to create the bitmap brush: const auto size = renderTarget->GetSize(); const auto pxSize = D2D1::SizeU(size.width * 4, size.height * 4); ID2D1BitmapRenderTarget* compatibleRenderTarget; HRESULT hr = renderTarget->CreateCompatibleRenderTarget(size, pxSize, &compatibleRenderTarget); if

问题 Does the bare LWJGL distribution use hardware rendering or software rendering? 回答1: LWJGL always uses hardware rendering. Since it is a games library, it just quits if no hardware rendering is available. From the LWJGL wiki: "Made the library throw an exception when hardware acceleration is not available on Windows. No point in running at 5fps is there? "(LWJGL wiki) There is a command-line switch org.lwjgl.opengl.Display.allowSoftwareOpenGL but I don't think you can force it to use software

问题 I have a shape (the red path below) and i have to apply to this path a TranslateTransform and a ScaleTransform transformation. But if i use the Shape RenderTransform property in this way: Path MyPath = new Path { Fill = new SolidColorBrush(Colors.Red) }; MyPath.Data = MyPathGeometry; TransformGroup transf = new TransformGroup(); transf.Children.Add(new TranslateTransform(50, 50)); transf.Children.Add(new ScaleTransform(2, 2)); MyPath.RenderTransform = transf; I get a drawing of this type:

问题 Let me start by saying that I am aware that you can specify the Content-Disposition in the header and use either "attachment" or "inline" and this question is NOT about that (at least not directly). I have a file with a .txt extension. I am noticing different browser behavior dependent on the content of that .txt file. If my file contains alphanumeric characters and I paste the location of the file into the URL bar of (say) Chrome, the file opens in the browser. If my file contains an "SI"

问题 First, play with the navigation menu on this page (left-side): http://bestds.com/TankStorage/ I'm using javascipt to update the dom backgroundColor of these li elements upon click. Firefox renders the updated DOM elements, but Chrom and Chromium do not render them. Using Chromium's document inspector, I can clearly see that the li element's background-color has been updated correctly, but they're not being rendered. What's funny, is it will go ahead and render the DOM changes after I hover my
