The type of drawing that was easier for me was the book because it was easier to draw the shape and lines of it so that it would look like a book.
What I found to be the most difficult when creating perspective drawings was that it was difficult for me to make them in a 3D type of shape.
A Vanishing point is the point at which receding parallel lines viewed in perspective appear to converge.
The difference between a one point, two point, and three point perspective sketch is they all have different sides of the drawing like different angles.
A perspective drawing differs from a isometric drawing because isometric drawings are more of shapes but perspective drawings are more of drawings of items like the book and remote I did.
