How to make the geometric sketch body and make it stand out the plaster feel

I'm also studying art! I'm a senior in high school! Learning to draw is really difficult at first!

I always feel impatient when I study! I always feel that the painting is not good! Very lost!

I'm depressed! These are quite normal! As long as you get through this difficult period!

I'm sure you'll make a lot of progress! Then let's get down to business!

First of all, simple tricks!A you can use the pen sassafras method! When your own picture feels very dim!

The outline of the object is too rigid! You can use the pen to delicately retouch! It will be useful to do more with less!

b Charcoal Block Method! When you feel that the dark side of your picture is not dark enough! You can use the same charcoal or charcoal pen as you usually use to wipe it down!

Make the transition! You'll feel like your picture comes to life! Of course, this is a matter of grasping a degree!

Otherwise, your picture will be confused! You can't see the contrast and change of light and dark! c with a brush method!

In the composition of the picture! Erasers can be cleaned with a brush! It can make the picture neat and clean!

At the same time, you can use a brush to make a transition when covering a large key! The picture will be hazy! Facilitates effective depiction of details!

dTry to use crude paper when choosing paper! Rough paper helps us to show contrasts better! If you choose smooth paper!

If you don't have the skills to get home! Then your picture will be easy to blur!

Experience to talk !a. When constructing the contour, we must pay attention to the proportional relationship between the object and the object! Keep comparing!

Try to use simple lines for simple outlines! In this way, the picture looks clean and refreshing! Don't use force to draw the outline!

This makes it difficult to modify the object! b Draw shadows! The shadow is the darker part of the picture!

It's not blind blacking when it comes to constructing shadows! It's about embodying a process of transition! From dark to faint!

If you want the picture to look and feel, you need to correspond to the surrounding background! Make the picture look comfortable! Suitable!

cLet the picture have a three-dimensional effect! This brings us to the contrast of the pictures! When the contrast between the object and the surrounding environment is not strong enough!

It's hard to feel the three-dimensionality of an object! At the same time we should weaken the edge line of the object! This makes the object look very sensitive!

But be sure to pay attention to the spatial relationship between objects!

Hope you are satisfied!

Totally hand-played! Do not copy or steal!

It would be better to paint hard things with hard lead in the gray part, and the texture depends on the highlights, and the volume depends on the gray part.

1 You can't look at the parts, you have to look at the whole thing.

2 Compare more and find out the difference between light and dark, because shadows and shadows are not the same.

3 Multi-Touch Canvas Pleats can exercise a sense of volume.

4 Volume is composed of multiple faces, it is said that it has been set off to highlight the volume, to be comprehensively painted, the bright side must be set off by the dark side to appear bright.

5 Pay attention to reflections.

6. Be careful with your pen, don't draw the picture very well, try to be as careful as possible, and don't be in a hurry.

7 It is best to use a pen that changes with the volume and shape of the object.

Friends who have been exposed to sketching know that plaster geometry is a compulsory course for beginners to learn to draw! Relatively speaking, the structure of geometry is simple, and it is the basic composition and expression of all complex shapes, so geometry is the most important step in the introduction of art.

In the following Beijing College Entrance Examination Intensive Training Class, I summarized and summarized the 6 major problems that are common in the process of drawing gypsum geometry.

1) The shape is crooked. This is because the symmetrical center line of the object is not found when the shape is formed. Therefore, when starting the draft, the left and right sides should be started at the same time and compared with each other.

2) The composition of the picture is too "empty" or too "full". Objects in the picture appear "empty" if they are small and concentrated; Objects in the picture that are too large and scattered will appear "full". This problem is avoided by finding the entire outline of the geometry at the beginning of the drawing, and then determining the shape of each object.

3) Light and dark control, the outer contour line is too "virtual" or too "real". The processing of the contour line is generally not too "real", too "real" is not easy to express the space, but it can not be "virtual", the contour line is generally relatively backward relative to the proximal end of the object, so it is more "virtual", but no matter how "virtual" it is, it is also real. This requires us to be good at comparison and observation, and pay attention to controlling the rhythmic relationship between virtual and real contours.

4) The perspective is not in place, and the contrast between distance and proximity is too small. The basic law of perspective is that the near is large and far small, and some students often draw objects without perspective, which is caused by insufficient understanding of the basic laws of perspective. Therefore, when we paint, we should grasp the laws of perspective, strictly grasp the relationship of proportion, and display the object as objectively as possible.

5) The tone of the picture is "gray". The reason for the appearance of "gray" is that the depiction of the bright part of the object is relatively weak and the distinction between the dark part is relatively weak, and the contrast between light and dark is not clear. At this time, we can increase the boundary between light and dark to reduce the tone of the bright parts and increase the brightness, and this problem is solved.

6) The picture is "flowery", "average" and "rigid". A lot of beginners are prone to problems. The reason for the "flower" is that there are too many parts of the object depicted, too fine, too broken; The reason for "average" is that the depiction of objects is not primary and secondary; The reason for the "rigidity" is that the depiction of the object lacks hierarchical changes and is too rigid.

In the final analysis, these problems arise because beginners in sketching do not observe enough as a whole, so they are lacking in overall performance. This requires us to pay attention to the whole when observing, distinguish the primary and secondary relationships between still lifes, and adjust the layout strictly according to the primary and secondary structure of the whole when depicting, so that the part and the whole can be well integrated.

Of course, sketching also includes creative sketching, subtle sketching, landscape sketching, etc., but the general traditional learning process is the above three stages.

Today, let's talk about the learning system of gypsum geometry.

The study of gypsum geometry must first learn single gypsum and then combine gypsum. In the monomer, draw the cube first, and then draw the circle.

First of all, because the square is angular, the relationship between light and dark is strong, and it is easy to lay out the tone; The tone of the circle is too complex, the relationship between light and dark must be observed and found by yourself, and the arc is more difficult to grasp than the straight line. Secondly, the core logic lies in the logic of faces, and the learning order of the cube is less face-multi-faceted, and the more surfaces of the object, the later it is learned; The logic of the circle is actually that the cube continues to divide and cut into countless faces, forming a circle. The above is the logical order in which gypsum geometry is learned.

Monomeric stage. Cubes (few-multi-faceted).

1.Triangular pyramid 2Cube 3

Cross penetrating body (pyramid and cuboid penetration) 7Cross interspersed body (two cuboids through) 8Dodecahedron 9

Combination phase. 1.Combination of two geometries (simple objects)2Combination of two geometries (complex objects)3Three geometry combinations 4A combination of four or more geometry.

The above is the teaching system of the gypsum geometry stage.

Next, I will share some of the teaching methods and drawing steps of geometry, which can be learned or taught in this way.

Here we must emphasize the steps, although the masters are easy to come by, and painting should not be limited to death, but for learners, there must always be a set of correct ideas and systems. This set of steps is divided into more detailed, every point and requirement is very clear, the thinking is clear, and the logic is rigorous.

The plaster geometry sketch tutorial is as follows:

1. First of all, the gypsum geometry should be visited in a certain way of collocation and combination, and the requirements should be staggered, and the near and far virtual reality should be expressed.

2. Place the sketchpad, fix the sketch paper on the sketchboard, and place the spotlight on the side of the gypsum geometry combination, so that the light source can fully divide the boundary between light and dark.

3. Start to take shape. It is required to first examine the perspective relationship, pay attention to the interaction between the near big and the far small, the near real and the far virtual. At the same time, pay attention to the intersection of perspective trends and the eye level.

4. Comprehensively observe the layout, reasonable composition, and leave a certain amount of space around the four sides of the picture. When taking shape, first draw the external shape of the geometry, and then depict its deconstruction direction, so that the shape can be portrayed most accurately!

5. After the shape is done, it is to lay the tone and draw the relationship between light and dark. First of all, the entire dark side is represented, a single tone, no change is required, and then the gray side is laid out, paying attention to the contrast of the two tones.

6. Depict the dark side to distinguish the projection from the dark side of the geometry itself, it is recommended to add a faint level on the bright side, and then simply lay out the background. This way, there are two levels of light and two levels of darkness. Be sure to pay attention to the boundary between light and dark not to be too rigid, and to use soft lines to "pile" it out many times, rather than using it to "carve" out.

7. Begin to depict the transition line between light and dark, and you can add a small gray surface on the bright surface. In the process of drawing, you can put the drawing board at a distance, squint your eyes to observe the overall effect of the stroke, and avoid "greasy" and "dirty" situations.

8. Gradually depict layer by layer until the overall effect is completed.

9. In-depth depiction of details, such as the potholes and broken corners on the plaster statue, the folds of the lining cloth at the back, etc., make the picture more exciting, and constantly fine-tune the relationship between light and dark!

<>1. Composition Shou Su first determined the height, width and narrowness of the plaster statue, with a slightly smaller space above and a slightly larger space below. The space facing the face is also slightly larger. Then use straight lines to draw the large proportions and perspective relationships of the head, chest, neck, seat and facial features. Quiet.

2. Grasping the shape of geometry in the large proportion relationship and then draw the facial features, bone points and muscles and the boundary line between light and dark. It is necessary to use the assistance of horizontal lines, vertical lines, and oblique square lines to draw the proportions and turning points, from the outer contour to the facial features, and then use the facial features to correct the external contours, and repeatedly correct them, and sketch the shape and structure of the plaster statue with straight lines. The line should have a change in weight, virtual and real.

3. Spread the tone.

Starting from the large boundary between light and dark, draw the two major parts of light and dark, and then lay out the four fasts (head, neck, chest, seat) and the large volume of the five senses.

4. In-depth portrayal.

Starting from the large structural relationship, the light and shade of the facial features, bones, bone points, and muscles are changed.

Draw it out (note that void is not a blurring of the structure, but a weakening of contrast). In the shaping of the three major faces and five tones, it is necessary to find out the brightest spots, the darkest spots and the strongest reflective places of the entire plaster image, the performance of the middle tone should be delicate, and the facets should be clear, this part can expose the lines, and the lines should change with the structure.

5. Overall adjustment.

This step is more to see and analyze, to see whether the overall sense of light, texture, and weight of the picture is expressed, and you can also carry plaster.

For example, make analytical adjustments to the overall picture. In the end, the whole picture achieves a vivid and harmonious effect.

The steps for drawing plaster geometry are as follows:

1. First use a 2B pencil to take shape, express the geometry with lines, and grasp its perspective structure.

2. Spread the overall large color tone to determine the sketch light and dark relationship of geometric objects.

3. Wipe the picture precipitation tone, and represent it according to the volume structure of the geometry.

4. Carry out in-depth shaping, depict the details of the geometry, and adjust the tone and line of the picture.

Summary: To sketch geometry, it is necessary to understand the relationship between light and dark objects, and then depict them in depth, which is an essential step for sketching.

Beginner sketch drawing geometry method:

The sketch geometry step is a more formalized technique in sketch modeling. In the sketch basics, the geometry step will not change because of the different objects to be drawn, and the geometry step technique runs through the overall operation process of the sketch from beginning to end, it guides how to start, how to proceed and how to end the sketch, so the geometry step step technique is the sketch technique that beginners need to master first.

The simpler the sketch object, the lower the difficulty of drawing, and the clearer and more complete the operation order of the steps. Since the plaster geometry is the most sketched object"Simple"form, so beginners should take this opportunity to first deal with the technical topic of sketching geometry steps.

Beginners start drawing with geometric plaster to exercise the feeling of shape, etc.

You can start with a single plaster and then combine the plasters. You can draw the plaster structure first, and then paint the light and shade ones.

Pay attention to the ratio of length, width and height of the plaster when drawing the plaster, for example, draw a cylindrical plaster – pay attention to what is the ratio between the width of the plaster and the height of the plaster.

When drawing the plaster combination, we should also pay attention to the proportional relationship between the various plasters, such as the position relationship between gypsum A, gypsum B and gypsum C, and the proportional relationship between the length, width and height of gypsum A, B and C.

The above is just a brief introduction to me, I hope it can help you) ps: beginners are recommended to buy a better template, starting with copying.
