A wide variety of looks can be achieved through shading and lighting. Source: Paperclip.
This week, we will explore the lights and shading from Blender's raytracing render engine: Cycles. We will implement a portion of these functionalities into your SimpleRT ray tracer next week.
<aside> 📖 In lecture, we talked about shading techniques to make the geometry appear smoother without adding more geometry. We can toggle Phong shading for objects in Blender's viewport (scanline renderer), and also in Cycles. We will compare how Phong shading looks, and how it compares with adding actual geometry (subdivide).
</aside>
Open Blender, delete the default cube. Keep the camera and the point light.
Add a UV sphere. Add a plane, scale it 5 times (shortcut S, 5), then move it down along the z-axis by 1 (shortcut G, Z, -1).
Go to Properties Editor → Render Properties, and set Render Engine to Cycles. To preview your render, set your viewport shading to Rendered.
