 I am Supriya Apasnur working as an assistant professor in civil department from Walton Institute of Technology, Sulapur. Today's session we are going to see the one point and the two point perspective. These are the learning outcomes. At the end of this session students will be able to draw need perspective view drawings of an object. So there are different types of the perspective such as the one point perspective and the two point perspective. So we are going to see both. So in this the vanishing point, the single point on the horizon where all the lines on the ground level they seem to come together. So they are drawn to the vanishing point. Next is the horizontal line that is drawn in the top from the top of the paper on the top corner of the paper. So the place where the land and the sky meet orthogonal lines that connect to the vanishing point. So actually perspective it is the art of representing the 3D that is the three dimensional view of an object which can be presented on a two dimensional medium or the two dimensional surface. So actually it doesn't represent the true shape or the size of an object. It is just the 3D model which can be presented on the paper. So in the one point perspective you have one vanishing point whereas in the two point perspective you have two vanishing points. So here you can see the horizontal line which will be drawn from the top of the paper that is the top side of the paper. So the vanishing point, the vanishing point will be drawn at the eye level or the horizontal line and the orthogonal lines that is the projections that are parallel but not the parallel projections which the lines that are drawn parallel and appear to get closer and closer and they are actually joined to a vanishing point, they are joined to a point that is called as the vanishing point. So this is how the one point perspective can be represented. So actually one point perspective it can be used to draw the images such as the roads and the railways whereas the two point perspective it can be used to draw the interior of the building. So first of all let's see take an object such as a cube or a box. So this is the front view which is drawn on the ground level. So this is the front view of the object. So let's see what is the 3D of this. So this is the front view of the object. So this is the horizontal line. So on the horizontal line itself the vanishing point will be placed and this is the eye level of the object. So there you can see that this is the box which has the four corners. So all these corners has to be joined to the vanishing point. They are joined to the vanishing point and you are supposed to take an arbitrary line. This is the vertical line which is taken arbitrarily and which will be parallel to this one of the edge of the box. So when you take the vertical line it cuts the orthogonal lines. These are the projections which are drawn called as the orthogonal lines. So while taking the vertical line it cuts the orthogonal line somewhere here. So from there itself you are going to draw a horizontal line which will be parallel to the horizontal line or which will be parallel to the one of the edge of the box. So this is the top view of the top view of the box which is presented. So these are the what you can say over all the 3D of that box itself. So this is the object which is drawn below the horizontal line. So let's see what happens when the object is drawn above the horizontal line. So in the same way you have to take the front view of this, front view of the object and draw all the corners, join the corners of these objects to the vanishing point and then arbitrarily you have to take the vertical line which will be parallel to one of the edge of the box. And likewise join these corners and when it cuts the orthogonal line somewhere here at this point from that point itself we are going to draw a horizontal line which will be parallel to the horizontal line. So then that this objects the projections of the box which represents the bottom view of the object. So this is how you can differentiate when the object is drawn below the horizontal line you get the top view of that object and when it is drawn above the horizontal line you get the bottom view of that object. So this can be differentiated in the one point perspective and let's see when the object is drawn on the horizontal line itself. So this is the object which is drawn on the horizontal line and these are the corners as two corners are visible to you. So join these two corners to the vanishing point. So these are nothing but the orthogonal lines and then arbitrarily you have to take the vertical line over here which will be parallel to this one and then join these corners. So this is how the perspective of the one side of the object is visible to you. So this is how the one point perspective it is used to present the images of the roads and the railways. So here you can pause the video for two seconds and try to give the answer for this. What are the elements of the perspective? Hope so you have got the answer. So the three components essential to the perspective are the orthogonal that is the parallel lines, the horizontal line and the vanishing point. So as to appear farther from the weaver the objects in the compositions are rendered increasingly smaller as they are near the vanishing point. So let's see the two point perspective. So the two point perspective it is actually used to draw the interior of the buildings. So all the 3D model can be done in using the perspective. Actually it doesn't represent the true shape and the size but it can be represented for the imagination. So it's a two point perspective. So draw a horizontal line from the towards the top of the page and then on this horizontal line itself you are going to place the vanishing points which are at the two edges of the page and then this is the front view of that object which is drawn. So from the front view of the object you are going to mark the height of the object horizontally which is taken over here and then a vertical line is drawn in between the two vanishing points which will be exactly in the center of the vanishing points and below on the ground level itself the vertical line is to be drawn till the height of the object. When the vertical line is drawn you have two corners over here. So that two edges of the vertical line are supposed to be joined to the vanishing points. So while joining to the vanishing points you are supposed to take the height of this. So while joining to the vanishing point you have the height of this object. So then drop a parallel line that represents the height of the object and then it cuts the orthogonal projection somewhere here on this point itself. So from that point itself you are going to drop a vertical line which will be parallel to this vertical line. So actually all the points which you get they are supposed to be joined to the vanishing point. So drop a vertical line which represents the backside of that object itself to represent the back form of the objects. So next step when you get the vertical lines you have the it cuts the orthogonal line over here. So as you get this point this point has to be joined to the vanishing point over this corner that is the cross connection it should be. So after this year you get one more point this point has to be joined to the second vanishing point. So likewise the back form of the backside of the boxes it is formed the whole backside of the form is or backside of the object is formed overall. So this is how the in the two-point perspective it is presented. So in the two-point perspective you have two vanishing points whereas in the one-point perspective you have one vanishing point. So these are the MCQs. These are the points at which the edges of the object appear to be converging. This point is seen at the eye level that is on the horizontal plane. Here are the MCQs that is the first option is station point. Second is the piercing point. Third is the exit point. Fourth is the vanishing point. Hope so you have got the answer. Vanishing point is the right answer for this. This is the second MCQ. These are the references. Thank you.
