How to Render OpenGL Frames in C Builder with TFrame1?

Rendering an OpenGL Frame in C Builder

In order to render an OpenGL frame inside a form, the code provided in the referenced link can be modified as follows:

Replace TForm1 with TFrame1 to embed the OpenGL rendering in a specific area of the form.
Use TForm::Handle as the window handle for initializing the OpenGL context.

Code Snippet:

<code class="cpp">// Initialize OpenGL
int TForm1::ogl_init()
{
    if (ogl_inicialized) return 1;
    hdc = GetDC(Form1->Handle);             // Get device context
    // ... (Remaining OpenGL initialization code)
    return 1;
}</code>

Additional Considerations:

The provided code initializes an OpenGL rendering context for C Builder 5 (BCB5), but the principles can be applied to other versions as well.
For more advanced OpenGL functionality, consider using libraries or frameworks that provide cross-platform compatibility and improved efficiency.
