• Graphics software (e.g., Adobe Photoshop, GIMP)
• Drawing tablets

Teaching Learning Activities

1. Begin by introducing the topic of output primitives through a brief lecture covering the fundamentals of digital images.
2. Define pixels and straight lines as basic building blocks for creating images.
3. Explain how output primitives are used in rendering graphics on display devices.
4. Define pixels as the smallest unit of a digital image.
5. Discuss the properties of pixels, including color and position.
6. Demonstrate how pixels are arranged in a grid to form images.
7. Introduce the concept of straight lines and their properties in digital images.
8. Use graphics software to demonstrate how pixels form an image.
9. Show how straight lines are created using pixels.
10. Ask students to practice creating straight lines using drawing software or drawing tablets with different line thicknesses and angles.

Assessment

1. Explain the concept of a pixel and its role in computer graphics.

2. What is the significance of pixels in computer graphics, and how are they utilized in creating straight lines?
