Follow the given steps:
- Open the ch02_08_ajax-car.html file using your web server.
- You should see something like this:
- The reason we selected the LINES model instead of the TRIANGLES model is to easily visualize the structure of the car.
- Find the line where the rendering mode is being selected and make sure that you understand what the code does.
- Go to the draw function.
- In the drawElements instruction, change the mode from gl.LINES to gl.TRIANGLES.
- Refresh the page in the web browser.
- What do you see? Can you guess why the visuals are different? What is your rationale?
Lights
Illumination helps us visualize complex geometries more clearly. Without lights, all of our volumes will look opaque, and it will be difficult to distinguish their parts when changing from LINES to TRIANGLES.
