Teaching Learning Activities

I will start the lesson by asking students what they know about parallel and prespective projection. Encourage them to share their thoughts and experiences.

I will introduce the concept of projection matrices and their significance in representing projection transformations.

I will introduce the concept of homogeneous coordinates and how they are used in projection transformations and derive the parallel projection matrix for orthographic projection using linear transformations.

I will explain the elements of the parallel projection matrix and how they relate to the projection process.

I will introduce the concept of perspective division and how it affects perspective projection and derive the perspective projection matrix using homogeneous coordinates and perspective division.

I will explain the elements of the perspective projection matrix and how they relate to the projection process.

I will ask students if they have any confusion related to today topic and at last i will summarize the lesson in brief.

Assessment

• Explain the concept of a projection matrix and its role in representing projection transformations in computer graphics.
• Discuss the elements of the perspective projection matrix and their relationship to the projection process.
• Describe the elements of the parallel projection matrix and discuss their significance in the projection process.

Evaluation

• Provide examples of real-world applications where parallel and perspective projections are used, and explain how projection matrices are employed in those contexts.
