C. Motivation
-so before we start, I will group you into two
-and there are pictures in the board, in the left is an isometric and in the other side is the orthographic drawing. All you have to do is to write the differences between those two, on the board, you need two volunteer for your group
- in one minute, the one should write their answers on the board and the other one should get those answers from the rest of the group. Ill give you 5min. for that and time starts now.
-time’s up! We will now count your answers
-the group ( ) is the winner!
IV. Lesson Proper
1. Unlocking of Difficulties
- So today we are going to talk about Parallel and Angular Perspective
- Parallel perspective has only one vanishing point where the projection lines came from, can you follow? - yes maam
- Very good! While the angular perspective has two ore more vanishing point.
2. Application
-today I’m going to teach you how to draw a parallel and angular perspective, so first we need to draw the horizon. Can you follow? You should try it also on your papers. And then draw the front view of the object. Anyone who wants to try it on the board?
- me! Ma’am
-we need to connect the edges of this object to the vanishing point using very light lines, which are the projection lines
-and the supply the missing lines.
-can you follow?
- yes!
-and now the angular perspective is more difficult than parallel.
-again we need to draw the horizon.
-then make a 120 degrees angle below it.
-project the lines
-it’s hard to identify where is the front view so we need to do trial and error by placing a straight lines on the side of the first vertical line. Project it.
Identify the missing lines and fill it to complete the whole object.
-ok, now let’s try another one, any volunteer?
- ma’am!
-ok, We will erase it first and all you have to do is to follow the steps I thought you.
-all done ma’am
-well done! Do you all now know how to draw angular and parallel perspective and the differences between them?
-yes ma’am!
3. Generalization
- -Now that you know how to draw parallel and angular perspective. Can you now differentiate the two? - ma’am parallel has only 1 v.p while angular has 2.
- Very well said!
4. Values Integration
-do you have any ideas on what is the relevance of perspective drawings?
- ma’am the importance of perspective drawing Is to enhance our drawing ability.
-very well said, another one is for us to view object on their other perspective views.
V. Evaluation.
- so now I want you to draw the angular perspective drawing of the given orthographic drawing.
-I’ll give you 10mins to finish that.
-done? -yes ma’am!
-pass your paper.
