Verification Benchmark
To verify the AI model's capability, look specifically for 'inter-reflections' (seeing one sphere reflected inside the other). Previous models like Gemini 3 often failed this specific physics calculation.
Thinking Process Visibility
In GPT 5.2, expanding the 'Thinking Process' is critical for debugging. It confirms if the AI successfully executed external actions, such as browsing the web for specific texture assets (street panoramas) before writing the code.

Ray-Traced Environment Generation
Target:
GPT 5.2
Create a WebGL simulation with two metallic spheres. Use any publicly available 3D street environment as the background. Allow adjustable parameters such as reflectivity, roughness, radius, position, and other material properties of the spheres. Ensure the scene handles ray-traced reflections between the objects.
Step by Step
Generating and Deploying the WebGL Simulation
- Enter the detailed prompt into the GPT 5.2 chat interface specifying the need for 'two metallic spheres' and a 'publicly available 3D street environment'.
- Click the 'Generate' button.
- Click to expand the 'Thinking Process' log to confirm the AI is searching for street panoramas and implementing WebGL 2 ray tracing.
- Wait for the code generation to complete.
- Click the 'Copy Code' button or icon on the code block.
- Open a text editor (e.g., Notepad, VS Code) on your computer.
- Paste the generated code into a new blank file.
- Save the file with an '.html' extension (e.g., 'simulation.html').
- Double-click the saved HTML file to open it in your web browser.
Verifying Ray-Tracing Accuracy
- Locate the 'Ray Tracing Controls' panel within the generated browser window.
- Click to expand the controls if they are collapsed.
- Set the 'Base Color' of both Sphere A and Sphere B to 'White' to neutralize color influence.
- Drag the 'Roughness' slider for both spheres to '0' to maximize mirror-like reflections.
- Drag the 'Metalness' slider to '1' to fully simulate metallic surfaces.
- Adjust the 'X' or 'Z' position sliders for Sphere A to move it closer to Sphere B.
- Observe the reflection on the surface of Sphere B; confirm that Sphere A is visible inside the reflection (physically accurate inter-reflection).
