Benefits of Extended Thinking Mode
The 'Extended Thinking' mode is crucial for physics simulation tasks like this, as it gives the AI time to plan light reflection interactions between objects before writing the code.
Real-Time Reflection Physics
When you change the position or size of an object (like a sphere), notice how the reflections on other objects (like a cube) change dynamically. This demonstrates that the GPT 5.4 simulation is 'physically correct'.
Visual Debugging Tips
If the simulation feels sluggish, lower the 'Reflectivity' or 'Roughness' values to reduce the computational load on the browser.
Prompts
Prompt 1: Basic Generation & Sphere
Target:
ChatGPT GPT 5.4
Create a ray tracing simulation file. Make sure it loads efficiently on a regular web browser. Allow me to change the properties of the sphere and make sure everything works.
Prompt 2: Adding Objects & Position Controls
Target:
ChatGPT GPT 5.4
Allow me to change the properties and position of the other shapes (cube and pyramid) as well.
Step by Step
Steps to Build a Ray Tracing Simulation with GPT 5.4 Canvas
- Open ChatGPT and ensure you have access to GPT 5.4 (paid plan).
- Click the model dropdown menu and set the 'Thinking' mode to 'Extended' to allow the AI to process complex physics logic in more depth.
- Click the 'Canvas' mode icon within the chat interface to enable side-by-side code previewing.
- Enter the first prompt asking the AI to generate an efficient ray tracing simulation file for web browsers, focusing on controlling sphere object properties (refer to the Prompt Card).
- Press 'Run' or Enter and wait for Canvas to generate the code and the control interface on the right.
- Enter the second prompt to add the ability to change the position and properties of other objects, such as a cube and pyramid.
- Use the sliders that appear in the Canvas interface to test parameters like 'Reflectivity', 'Roughness', 'Metalness', and 'Rotation'.
- Click the 'Download' button at the top of the code to save the .html file and open it in your browser in full screen.
