What is the proper OpenGL initialisation on Intel HD 3000?
Your code snippet handling OpenGL initialization and exit appears generally correct, but you may consider optimizing it using a loading library. A recommended approach is to use a loader library instead of performing the initialization yourself.
Suggested Improvements:
<code class="c++">int OpenGLscreen::init(void *f, int textures) { if (_init) exit(); frm = (formtype *)f; HDC hdc = GetDC(frm->Handle); if (!_used) { // Pixel format selection logic ... } // Create OpenGL context using a loader library hrc = CreateOpenGLContext(hdc); if (hrc == NULL) { ... // Handle context creation failure return 0; } wglMakeCurrent(hdc, hrc); if (!glewInit()) { ... // Handle GLEW initialization failure return 0; } _init = 1; _used = 1; ... // Continue initialization code </code>
<code class="c++">void OpenGLscreen::exit() { if (!_init) return; wglMakeCurrent(NULL, NULL); wglDeleteContext(hrc); _init = 0; }</code>
