Topenglpanel -

Unlike GDI or Canvas drawing, which are CPU-driven and 2D, TOpenGlPanel allows you to write directly to the GPU command buffer. When you hook into its OnPaint event (or OnRender in some variants), you are speaking directly to your graphics card.

This gives you a solid, ready-to-use OpenGL panel with smooth animation and clear structure.

It is particularly popular among developers maintaining legacy projects or building specialized engineering tools that require real-time 3D visualization within a standard Key Features and Benefits Encapsulated Context Management:

Because it renders directly to the GPU, it’s significantly faster than software-based drawing methods like for complex geometries. Getting Started: A Quick Example Once you’ve installed the package into your RAD Studio IDE , using it is straightforward: Drop the Component: TOpenGLPanel on your main form. Initialize: or a specific OnInitialize event to set up your lighting, viewport, and perspective. event, clear the buffer and draw your objects: __fastcall Unlike GDI or Canvas drawing, which are CPU-driven

procedure TMyOpenGLPanel.StartAnimation; begin FTimer.Enabled := True; end;

type TOpenGLContextHelper = class helper for TContext3D public procedure DrawCubeFace(FaceIndex: Integer; Size: Single); end; event, clear the buffer and draw your objects:

// Clear buffers Context.SetClearColor($FF1A1A2E); // dark blue-gray Context.Clear([TClearTarget.Color, TClearTarget.Depth]);

end; end;
