我正在使用什么SDL和OpenGL版本及实现

问题描述

我下载了SDL 1.2.14在Windows 7上并且我已经安装了Mobility Radeon X1800驱动程序.

I downloaded SDL 1.2.14on Windows 7and I have Mobility Radeon X1800 driver installed.

我正在使用Microsoft Visual C ++ 2010 Express.

I'm using Microsoft Visual C++ 2010 Express.

我在"VC ++目录"中添加了SDL包含和库目录

I added the SDL include and library directories in the "VC++ Directories"

我添加了以下其他依赖项: opengl32.lib; glu32.lib; SDL.lib; SDLmain.lib;

I added the following Additional Dependencies: opengl32.lib; glu32.lib; SDL.lib; SDLmain.lib;

我将SDL.dll添加到了程序文件夹中

I added the SDL.dll to my program folder

我没有添加任何opengl目录！

I didn't add any opengl directories!

#include "SDL.h"
#include "SDL_opengl.h"

bool running = true;

int main(int argc, char* args[]) {
  SDL_Init(SDL_INIT_EVERYTHING);
  SDL_Surface* screen = SDL_SetVideoMode(640,480,32,SDL_OPENGL);

  glViewport(0,0,640,480);
  glMatrixMode(GL_PROJECTION);
  glLoadIdentity();
  gluPerspective(45.0, 640/480, 1.0, 200.0);

  while(running) {
    glClear(GL_COLOR_BUFFER_BIT |GL_DEPTH_BUFFER_BIT);

    glMatrixMode(GL_MODELVIEW); // Swich to the drawing perspective
    glLoadIdentity();
    glTranslatef(0.0,0.0,-5.0);

    glBegin(GL_TRIANGLES);
      glVertex3f(-0.5f, 0.5f, 0.0f);
      glVertex3f(-1.0f, 1.5f, 0.0f);
      glVertex3f(-1.5f, 0.5f, 0.0f);
    glEnd();

    SDL_GL_SwapBuffers();
  }

  SDL_Quit();
  return 0;
}

该程序绘制一个简单的三角形.我在上面包括了2个头文件，而我的Opengl代码才起作用！

This program draws a simple triangle.I include 2 header files above and my Opengl code just works!

我不知道我的三角形是在GPU还是CPU上完成的.以及我使用的是哪个openGL版本?

I don't know if my triangle is done on a the GPU or CPU. And what openGL version I'm using?

我的意思是，我听说微软不再在其中更新opengl文件，并且它们使用OpenGL 1.1等的CPU实现.

I mean i heard that Microsoft don't update there opengl files any longer and that they use CPU implementation of OpenGL 1.1 or something.

我怎么知道我正在使用哪个版本的OpenGL?我可以在运行时检查吗?

How do I know what version of OpenGL I'm using? And can I check at run time?

如何知道我使用的是CPU还是GPU?我可以在运行时检查吗?

How do I know if I'm using a CPU or GPU implementation? And can I check at run time?

感谢您查看我的问题.

推荐答案

调用 glGetString

此处是Microsoft的glGetString文档. SGI文档，并告诉您该功能可以在gl.h和opengl32.lib中找到.
