To the users of the illustrator software to share the detailed drawing of three-dimensional perspective of the tutorial.
This paper introduces the method of drawing three-dimensional perspective drawing, which is also very characteristic and creative. Have a foundation of friends can see you have no use this idea, or is there any thought of the AI to draw a stereo perspective can also be used to operate, well, interested in a look at it: We will first say some perspective of the theoretical knowledge, And then say a single point perspective, a 2-point perspective, and an example of a 3-point perspective.
There are 2 main ways to draw a perspective chart. One is to use vanishing point (extinction point) and visual line to build objects without measurement of the drawing method, the other is a more accurate mathematical operation method. Choose the best drawing Method--no measurement method, this is the focus of this article.
The main feature of this approach is that it has a lot of flexibility. You can use it to draw a piece of work quickly, or you can use it to draw a line draft. Keep in mind, though, that this method is not the best choice if your finished drawing needs to be measured very accurately. For example: Draw engineering drawings or blueprints.
In this tutorial, I'm not going to discuss the exact and mathematical methods used, and all of these methods focus on the rules of the horizon. Well, let's use illustrator to get a better idea of how to use a method that doesn't need to be measured.
Set up the visual flat line
It is easy to draw a perspective picture.
1, from the top of the ruler drag and drop a ruler line, make it as a visual flat line. If you do not display the ruler, you can use Ctrl+r or perform the View menu > Display ruler. Then drag the ruler line from the left side of the ruler to mark the vanishing point.
2. Draw 2 anchor lines (straight lines) at any point in the artboard, then use the white arrow (direct Selection tool), select a control point (anchor) for the line, and drag it to the intersection of the horizontal and vertical ruler lines. When you point to the intersection, the arrow marks will change. Now you've got the kill line.
3, now use the same method, draw other line (VP). When you are done, you are named "Visual Flat" and a new layer is created.
Select all the lines on the horizon layer, and then click the Color box on the layer and drag it to the new layer. But before you do, hold down the ALT key. This will drag the selected item copy to the new layer and be in the same position (same as the original layer). Lock the horizon layer and continue drawing.
Draw a single point perspective
1, draw the visual line, and in this line select a point, it as the center of Focus, which will be as your point of death.
2, this step, you first want to determine where your object appears in the picture. If you put the object on top of the horizon, you are looking at it, and if it is underneath the horizon, then you are overlooking it. Continue to draw and place your object.
The following illustration is the object I want to draw. The 3 graphs on the left are basic graphics for the objects, representing the top, side, and front views of the object, respectively. The right image is an isometric view of the object. This is only a reference.
3, in the position you decide, draw the front view of the object. Front view has no vanishing point, vertical is vertical, horizontal is horizontal.
4, the front view of some of the control points (anchor points) and the vanishing point connected. I've found that the best way to connect a control point to an endpoint is to fix an anchor point and then copy the line. In doing so, you have an anchor point on the line that is on the vanishing point.
With the direct selection tool, select the anchor point (not the anchor point on the kill point) and move to the vicinity of the object control point (anchor Point). At this point, before you release the mouse, hold down the ALT key and copy the line.
Here's a little problem, because if you start by holding down the ALT key and clicking on the anchor point, you'll move the whole line. Only when you start to move the anchor point, then hold down the ALT key to normal operation. After you make a copy, use the direct selection tool to align the anchor points on the kill line with the control points (anchor points) on the object.
5, continue to draw the depth of the object. This step may require a bit of skill. According to the mapping principle of the perspective, the distance between all the lines disappearing from the vanishing point is getting narrower (pictured). The closer you are to the vanishing point, the narrower the distance between the lines. The best way is to start by calculating the proportions.
Observe the relationship between the lines you draw and observe the lengths of each side as you draw. In addition to the use of intelligent methods, but also mainly by the naked eye observation.
6, remove unwanted lines. I use scissors tool to cut out the line. I've deleted 1 or 2 long lines, because if you need to build them later, it's easy to make a quick copy. Use the white arrow to align the anchor points when the arrows are marked white.
7, quickly clean up the connection point. Use the direct selection tool to select 2 anchor points, and then press Ctrl+j (Object menu > Path > Connection). If the dialog box pops up, then 1 anchor points are just above the other anchor point, and you can create a single anchor point. If you execute a connection command without a pop-up dialog box, then the 2 anchor points are separated from a certain distance, you can also execute the command, the following is the result of drawing objects with a single point of perspective.
Draw a 2 point perspective
1, draw a visual flat line, and then select 2 points on this line as the vanishing point. The location of the vanishing point will affect the result of your drawing, and if the distance between the 2 vanishing points is close enough, the image will be severely distorted.
2, if 2 points away from the object of equal distance, then you will get a feeling flat, no fluctuations, no tension in the graphics.
3. If you want to get a view with tension, then the distance between the 2 vanishing points to the object cannot be the same. A vanishing point is closer to the object, and the other should be farther away. It is important to do so, and the second is the vanishing point.
4, when you determine the vanishing point, start to draw the front edge of the shape, height can be arbitrary, but to calculate a good proportional relationship to draw the rest of the shape of the part.
5, draw the left end point (LVP) to the first line (the front of the shape of the edge) the top anchor and bottom anchor point of the kill line, draws the right endpoint (RVP) to the top of the first line (the edge in front of the shape) and the end of the bottom anchor point.
6, draw the 1th big shape.
7, reference just draw the 1th shape, to draw another large shape.
8, delete unwanted lines, and then add details.
9. The following figure is an object that is drawn with a 2-point perspective. Note: The outside is thicker than the inner edge.
Draw a 3 point perspective
1, the establishment of the visual line, first marked the 1th, the 2nd vanishing point. The 3rd vanishing point may be on the top of the horizon, or it may be below the horizon, or close to the center of the work. But in many cases, the 3rd vanishing point should be far from the page. It should be more of a reminder of the role, not the dominant role. If the 3rd vanishing point is too close to the horizon, the object will be severely distorted. Remember: The best time to use the 3rd vanishing point is that you are drawing objects that are very large or very small.
2. The next step is the same as the previous method of drawing the 2-point perspective, but all the lines must disappear from the new extinction point.
3, connect the edge to the vanishing point, draw the 1th big shape.
4, refer to the 1th shape, to draw another large shape.
5, use scissors tool to cut off the line.
6, use the direct selection tool, so that all the anchor points aligned.
7, now the object looks more tidy than before, so it is easier to add further details.
8, cut off the unwanted parts.
9. The following figure is an object that is drawn with a 3-point perspective.
Well, the above information is small compiled to you illustrator of this software users brought to the detailed drawing of three-dimensional perspective of the tutorial to share the full content of the text, you see the users here, small knitting believe that everyone now see here is very clear it, I hope that the small series of the above to share the tutorial can give you users to take the help of swimming.
