Exploring 2D Geometric Transformations

What is a basic 2D geometric transformation?

• Translation, projection, and inversion

• Rotation, translation, and perspective

• Translation, rotation, and scaling are basic 2D geometric transformations.

• Reflection, dilation, and shearing

How are transformations represented using matrices?

• Transformations are represented using matrices by applying subtraction to vectors.

• Transformations are represented using matrices by adding vectors together.

• Transformations are represented using matrices by applying matrix multiplication to vectors.

• Transformations are represented using matrices by dividing vectors by scalars.

What is the purpose of composite transformations in 2D graphics?

• To limit the number of transformations that can be applied to a single object.

• To create 3D effects in 2D graphics.

• To apply transformations only to individual objects without combining them.

• The purpose of composite transformations in 2D graphics is to combine multiple transformations into a single operation for efficiency and simplicity.

Explain the concept of the viewing pipeline in 2D graphics.

• The viewing pipeline is a method for rendering audio in 2D environments.

• The viewing pipeline only applies to 3D graphics without any transformations.

• The viewing pipeline in 2D graphics is the process of transforming 3D objects into a 2D representation through a series of transformations and projections.

• The viewing pipeline in 2D graphics is solely about color correction.

What is the viewing coordinate reference frame?

• A method for rendering textures on surfaces.

• The system used to measure distances in 3D space.

• The coordinate system used to define the viewer's perspective in computer graphics.

• The algorithm for calculating lighting effects in scenes.

Describe the window-to-viewport coordinate transformation.

• The viewport coordinates are always larger than window coordinates.

• Window coordinates are fixed and cannot be transformed.

• The window-to-viewport coordinate transformation maps window coordinates to viewport coordinates by scaling and translating them to fit the display area.

• Viewport coordinates are used for printing documents only.

What are 2D viewing functions used for?

• They are used for storing 3D data in a 2D format.

• They are used for projecting 3D scenes onto 2D displays.

• They are used for creating 3D models from 2D images.

• They are used for enhancing 3D graphics performance.

What is clipping in the context of 2D graphics?

• Clipping refers to the process of adding textures to 3D models.

• Clipping is the method of merging multiple images into one.

• Clipping is a technique for enhancing image resolution.

• Clipping is the process of restricting rendering to a defined area in 2D graphics.

How does clipping improve rendering efficiency?

• Clipping enhances the quality of textures in rendering.

• Clipping improves rendering efficiency by limiting processing to only visible objects, reducing computational load.

• Clipping has no effect on rendering efficiency.

• Clipping increases the number of objects processed for better detail.

What are some common types of clipping operations?

• image clipping

• circle clipping

• Point clipping, line clipping, polygon clipping, text clipping

• audio clipping
