Is there a good way for displaying unicode text in opengl under Windows? For example, when you have to deal with different languages. The most common approach like #define FONTLISTRANGE 128 GLuint list; list = glGenLists(FONTLISTRANGE); wglUseFontBitmapsW(hDC, 0, FONTLISTRANGE, list); just won't do because you can't create enough list...

My nephew is an aspiring game developer. I have taught him a bit of C/C++, and suggested he learn that for a start. Once he has come to grips with that, which game/graphics API's do people suggest he learn? I would think DirectX would be current industry standard, but with more games looking to go X-platform then maybe Open-GL would be...
I recently found out that OpenGL 3.0 was released a week ago. I glanced through the specification and read through some of the forum posts on the Khronos message board, and... I'm devastated. Not only did they not release the promised object model, but they deprecated most of the functionality that, IMHO, made OpenGL great, in favor of a...
Multisampling is a way of applying full screen anti-aliasing (FSAA) in 3D applications. I need to use multisampling in my OpenGL program, which is currently embedded in a wxWidgets GUI. Is there a way to do this? Please respond only if you know the detailed steps to achieve this. I'm aware of enabling multisampling using WGL (Win32 exte...
Hi, I'm trying to do a simple rotation in OpenGL but must be missing the point. I'm not looking for a specific fix so much as a quick explanation or link that explains OpenGL rotation more generally. At the moment I have code like this: glPushMatrix(); glRotatef(90.0, 0.0, 1.0, 0.0); glBegin(GL_TRIANGLES); glVertex3f( ...
The following code writes no data to the back buffer on Intel integrated video cards,for example, on a MacBook. On ATI cards, such as in the iMac, it draws to the back buffer. The width and height are correct (and 800x600 buffer) and m_PixelBuffer is correctly filled with 0xAA00AA00. My best guess so far is that there is something amiss...
