gpu, old hardware, 3d acceleration and a lib

i am writing a 2d lib which will have 3d acceleration but i'd like to do it in a way that it will efficiently run on older HW. Possibly typedefs to hide options/functions that your targeted mode does not support. (also there may be emulation func turned on) What are some of the things older HW do? here is a list of questions and things ...

Ugly WPF text rendering - can't disable hardware acceleration on Vista

I'm experimenting problems with text rendering in WPF (third party applications and mine too). Labels and other text don't display correctly, look a little blurred and are rendered with some random colored pixels around. I'm working on a low end crap machine (SiS Mirage 3 graphics) with Vista SP1, .NET 3.5 SP1 and graphics driver update...

Any high-level, hardware-accelerated 3D engine?

I am programming in Flash for a long-time. It is interesting that most of the things, including open source libraries, are very high-level in the Flash world. It is great because we can build things up quickly. But Flash is too slow (I want to do CV stuff, visual effect, generative art etc). I have tried glut, Processing, OpenFrameworks...

How can I accelerate the generation of the an MD5 Checksum within vb.net?

I'm working with some very large files residing on P2 (Panasonic) cards. Part of the process we employ is to first generate a checksum of the file we are going to copy, then copy the file, then run a checksum on the file to confirm that it copied OK. The problem is, is that files are large (70 GB+) and take a long time to complete. ...

Can you enable hardware acceleration with the Quicktime API on Windows?

Using the Quicktime API on Windows, there doesn't seem to be any API exposed to enable hardware acceleration. If you open movies with the Quicktime app, DirectX acceleration can be enabled by use of the GUI under the Edit/Preferences/QuickTime Preferences/Advanced Tab. Is it possible to pass a DirectX surface or similar to get H/W accele...

My OpenCL kernel is slower on faster hardware.. But why?

Hi folks, As I was finishing coding my project for a multicore programming class I came up upon something really weird I wanted to discuss with you. We were asked to create any program that would show significant improvement in being programmed for a multi-core platform. I’ve decided to try and code something on the GPU to try out Ope...

Which OpenGL functions are not GPU-accelerated?

I was shocked when I read this (from the OpenGL wiki): glTranslate, glRotate, glScale Are these hardware accelerated? No, there are no known GPUs that execute this. The driver computes the matrix on the CPU and uploads it to the GPU. All the other matrix operations are done on the CPU as well : glPushMatrix, ...

QGLWidget and hardware acceleration ?

Greetings all, Does simply subclassing QGLWidget and reimplementing paintEvent() make use of OpenGL and hardware acceleration? I create a QPainter and draw QImages in this paintEvent(). What happen inside the paintEvent() method of QGLWidget? Does it convert the images(QImage,QPixmap) into OpenGL textures? Does it use hardware acceler...

How to achieve smooth (hw accelerated) transitions in the Android browser?

Hi, the title is self-explaining. On iPhone, Mobile Safari is WebKit based and supports hardware-accelerated -webkit-transform CSS properties. To be specific, I use the translate3d() transform. What alternative is there for the Android browser? I need it to work on Android 1.5. Thanks in advance. ...

WPF Control embedded in Winform causes App Crash

I am working on an outlook addin where we are using WPF user control embedded in a Windows form using ElementHost. This app crashes on only few machines intermittently.After analyzing crash dump,the WPF rendering thread seems to be causing this crash.The stack trace in the windbg looks like FAULTING_IP: msvcr80!memcpy+5a 7814500a...

How to tell whether an OpenGL context is hardware accelerated?

I know that if the openGl implementation does not find a suitable driver it happily falls back and render everything in software mode. It's good for graphics applications but it is not acceptable for computer games. I know many users using Windows XP and if the user does not install the video card driver for his GPU then the OpenGL won'...

Cross platform hardware accelerated 2d C++ app?

I know a decent amount of C++, and now I wanted to explore making a game. I was wondering what the best approach would be in terms of writing a hardware accelerated game that's still cross-platform (Windows/OSX/Linux). It's going to be a 2d game, but intensive enough that a CPU renderer probably wouldn't cut it. I know there's OpenGL, b...

WPF Firefox 4 Top Bar?

How would one create the top bar such as in Firefox 4's Orange bar? I don't want to do my own window class as I still want to be hardware accelerated rather than sofware rendered. Is there a way to do this? ...

Using graphics hardware for audio processing in iphone app

We are developing an iphone app that needs to process audio data in real time, but we are suffering with performance. The bottlenecks are in audio effects, which are in fact quite simple, but the performance hit is noticeable when several are added. Most of the audio effects code is written in C. We think there are two places we can us...

Silverlight Hardware Accelerated Graphics

Is there anyway to create cross platform hardware accelerated games in Silverlight? (OpenGL binding or something similar) Does libraries like Balder usable for writing large 3D games (e.g MMORPGs) in Silverlight? ...
