The user interface will not refresh in a timely manner. For example the user clicks a button that runs a process and when that process is completed the results should be reflected on a grid that is displayed however we can determine the process is finished but it takes several seconds for the grid to display this data. If we turn hardware acceleration off the issue goes away. I have clients that have applications they run on the same machine that require hardware acceleration turned on. How can these two applications run on the same machine yet conflict over hardware acceleration? What types of things could cause this issue?

Even though I have a degree in Mathematics, I've always had the impression that programming in 3-D would be difficult. I've recently discovered though, that it's really not very hard. In fact, it's almost easy and a lot of fun—thanks to the Irrlicht 3-D graphics engine.

The Irrlicht 3-D graphics engine is written in C++ and allows you to get impressive results without a whole lot of code, as you'll see later in this article. With Irrlicht, you can write programs that will run under Linux or Windows and take advantage of OpenGL or DirectX. Irrlicht directly supports 3-D models in various formats, including Maya (.obj), COLLADA (.dae), Quake 3 levels (.bsp), Quake 2 models (.md2) and Microsoft DirectX (.X), among others. This means there are plenty of ready-made models available for download on the Internet that can be used with Irrlicht. Also, many tools are available for creating models and textures to use with Irrlicht.

When I was evaluating some other 3-D engines, I chose Irrlicht because it seemed to be the easiest to wrap my head around, while at the same time, it had all the features I wanted. Irrlicht supports both mesh-based animation as well as a skeletal animation system. With Irrlicht, materials can be layered to produce stunning effects. And most important, Irrlicht is extremely well documented with tutorials on-line as well as a very responsive on-line forum. Oh, and it's free. And, it's open source. ]]> Graphics Programming naher88 http://forums.codeguru.com/showthread.php?537313-3-D-Graphics-Programming http://forums.codeguru.com/showthread.php?537251-How-to-create-graphical-components-using-GDI&goto=newpost Thu, 23 May 2013 15:02:16 GMT Hi, I want to know that how to create graphical components using GDI+ like i have a box which will have input port/outport and those components can be connected to other components. Each components will have their own different properties using that user can provide the required inputs. Could someone suggest a way or provide any link or document available on this? Thanks cdeveloper Hi,
