Geometric Transformations in Computer Graphics

The lecture covers basic 2D transformations in computer graphics, focusing on translation, rotation, and scaling. It explains how these transformations change an object's position, orientation, and size, respectively. The session also introduces homogeneous coordinates, which simplify complex transformations by reducing matrix operations. The lecture emphasizes the importance of these transformations as building blocks for more complex operations in graphics.

What is the primary focus of the course discussed in the introduction?

• Computer Graphics and Visualization

• Artificial Intelligence

• Machine Learning

• Data Science

Which of the following is NOT a fundamental 2D transformation?

• Reflection

• Rotation

• Translation

• Scaling

What does translation primarily change in a geometric object?

• Color

• Orientation

• Position

• Size

In the context of rotation, what does the angle theta represent?

• Angle of reflection

• Angle of scaling

• Angle of translation

• Angle of rotation

What is the effect of scaling on an object's size?

• It only changes the orientation

• It only changes the color

• It changes both size and position

• It only changes the position

What is the main advantage of using homogeneous coordinate systems?

• They make objects appear larger

• They are easier to visualize

• They increase the number of matrix operations

• They simplify complex transformations
