Skipping and Tearing in Java Animation

阅读更多关于 Skipping and Tearing in Java Animation

问题 the following code draws a square with two smaller square rotating inside it. whenever you click an arrow on the keyboard, the whole system will move in that direction. however i'm having some problems with the image tearing and at times skipping (its small but still there). i was wondering if anybody knew how i could fix these issues w/o massively altering the code. import java.awt.*; import java.awt.event.*; import javax.swing.*; import static java.awt.Color.*; public class GUI extends

WPF: How do I prevent tearing with WriteableBitmap?

阅读更多关于 WPF: How do I prevent tearing with WriteableBitmap?

问题 I'm using a WriteableBitmap to display images I process myself at around 20 frames per second. This question (WPF: More efficient way of displaying quickly-changing images?) and this question (How to display quick-updating images without large memory allocation?) indicate that the best way to do this is by using a WriteableBitmap . The documentation for WriteableBitmap indicates that calling WritePixels() on the UI thread will cause the rendering thread to redraw the image: MSDN documentation

Tearing in my animation on WinForms C#

阅读更多关于 Tearing in my animation on WinForms C#

问题 I am using a library in which enables me to animate movement of WinForm elements (linked below), when I use it to move a transparent panel across the form (which has a picture background) there is an extraordinary amount of tearing. I believe the fix is to get winforms to refresh at a rate of 30fps without being laggy. I tried settings a timer to do This.Refresh(); at 30 times a second but it just ended up with slow loading. So how would I achieve a nice refresh rate of the form? The link

OpenGL tearing with fullscreen native resolution

阅读更多关于 OpenGL tearing with fullscreen native resolution

问题 I've got an OpenGL application with win32 api without glut etc...and I run into a problem with screen tearing in fullscreen. Basicly I have set WS_POPUP as a window style and resolution of my monitor as window size. I'm running on AMD radeon HD 7770 and I see terrible tearing! When I put WS_POPUPWINDOW style instead of WS_POPUP , the tearing is gone, however I have unwanted border around my scene. Another thing I noticed is fact, that the tearing disappears when the resolution is NOT native.

Tearing in HTML5 canvas?

阅读更多关于 Tearing in HTML5 canvas?

问题 I'm making a small game using the HTML5 canvas element. It works great, except that it has a scrolling background with obvious tearing happening in Firefox and Chromium browsers in Ubuntu. I'm pretty sure it's buffered because there isn't any of the flickering I'd expect; just tearing. Is there any way to work around this or time rendering to right after the last screen refresh? 回答1: Currently there is no way to control the actual repainting of a canvas element(which if there was, could

BitmapFactory.Options.inBitmap causes tearing when switching ImageView bitmap often

阅读更多关于 BitmapFactory.Options.inBitmap causes tearing when switching ImageView bitmap often

问题 I've encountered a situation where I have to display images in a slideshow that switches image very fast. The sheer number of images makes me want to store the JPEG data in memory and decode them when I want to display them. To ease on the Garbage Collector, I'm using BitmapFactory.Options.inBitmap to reuse bitmaps. Unfortunately, this causes rather severe tearing, I've tried different solutions such as synchronization, semaphores, alternating between 2-3 bitmaps, however, none seem to fix
