Unit-I Co-ordinate system

A 2D transformation in a coordinate system that only involves a change in orientation and not in position or size is known as a

• Translation

• Scaling

• Rotation

• Reflection

In 3D transformations, using homogeneous coordinates allows us to represent both the geometry of the object and the transformation in a single matrix, making it easier to perform

• Translation

• Scaling

• Rotation

• All of the above

Homogeneous coordinates are used in computer graphics because they allow for

• Representation of a point in a 2D or 3D space using a single equation

• Combination of translation, scaling, and rotation transformations in a single matrix

• Easy conversion between 2D and 3D representations

• All of the above

In 2D transformations, a transformation that changes the size of an object but not its orientation or position is known as

• Translation

• Scaling

• Rotation

• Reflection

A 3D transformation that involves a change in orientation and position of an object in 3D space is known as a

• Translation

• Scaling

• Rotation

• All of the above
