How an audience reacts to a film or performance all depends on how well it was produced, and the quality of the actors involved. When it comes down to it, the overall quality of any performance is dependant on how well the performers act, how they set the tone, their use of emotions, their gestures, etc. Every single small detail help play a part in the making of any act. And if the actors fail to fulfil their duties as performers, then the whole show will be ruined, and the audience will either be un impressed, or non existent.
Answer:
vanishing point- A vanishing point is a point on the image plane of a perspective drawing where the two-dimensional perspective projections (or drawings) of mutually parallel lines in three-dimensional space appear to converge.
orthogonal- elating to or involving lines that are perpendicular or that form right angles, as in This design incorporates many orthogonal elements. Another word for this is orthographic. When lines are perpendicular, they intersect or meet to form a right angle.
picture plane- in perspective, the imaginary plane corresponding to the surface of a picture, perpendicular to the viewer's line of sight.
