How to illustrate the manual production method of DIY three-dimensional paper art with examples

First, the materials needed for three-dimensional lily: white paper and scissors. Specific steps: prepare a square piece of paper, fold it into a triangle, then fold it again and make a crease in the middle of the triangle.

Fold the two corners of the triangle in half at an angle of 45 degrees, and the corresponding two corners are folded upwards. Fold the two corners of the appeal in half, and then subtract them with scissors at an oblique angle of 45.

Open it after cutting, with the convex angle outside and the concave angle inside. Fold the concave angle in half, all six angles are the same, and fold the lower part in the middle, so that the petals of lily will be more aggregated. It is better to curl the six petals with a thin wooden stick. When the thick roll is opened, it will recover. After the petals are rolled up, you can also add stamens and stems. A six-petal lily is finished. Second, the material needed for three-dimensional roses: colored paper. 2. Fold one in the middle and customize the width, about 1 cm.

After opening, the other side also repeats, based on the intersection with the diagonal. 3. Fold the two pairs into a square, and fold the vertex to the intersection of the two pairs, leaving a crease.

4. After opening, you can see that the crease is like this. Then, press the yellow line to leave a crease, and the other three corners will do the same.

5. Now the crease is like this, and then the middle will start to polymerize according to the crease. 6. Look down from above.

7. Leave a crease between two points and do the same for the other three points. 8. The crease is basically completed.

Turn it over and start to converge. 9. Polymerize slowly according to the crease.

10, convergence. 1 1. Fold the bottom up and open it for sorting.

What are the ways to make paper cups by hand?

The first hand-made work is a paper cup speaker.

Preparation materials: four paper cups, some toothpicks and an earphone. First, we cut a small hole at the bottom of two of the paper cups, so that the head of the earphone can pass through. This should be operated in the middle of the paper cup, which will increase the stability and aesthetics of the speaker. Then, we will put the earphone through the hole at the bottom of the cup. After wearing it, we will use two other non-porous paper cups as the base of the speaker, and use toothpicks to put the paper cup with headphones and the paper cup base together and fix them. Connect the music and we will hear the amplified sound.

The volume is still ok. After it is done, children can also use their brains to decorate it.

The second is to be a paper cup tiger. Preparation materials: a paper cup, colored cardboard.

In fact, it can also be made into frogs, rabbits, lions and the like. The steps are the same, and children can do whatever they like. The specific method is to put a beautiful coat on the paper cup with colored cardboard. Let's take the tiger as an example. Paper cups made of yellow cardboard become the tiger's body, and then the tiger's eyes, nose, mouth and the king's words on the top of his head are glued to the paper cups.

Don't forget to stick the tiger's tail on the other side of the paper cup. Such a domineering and lovely little tiger was created.

This is a very interesting ornament. The third is a paper cup lantern.

Preparation materials: a paper cup, a wire, a cotton thread and a red marker. First, paint the paper cup red, and then draw the paper cup into an equal straight line with a colored pen. Cut the paper cups in a straight line, but don't cut them short. Gently press out the cut paper cup by hand, so that the main body of the lantern comes out.

Fix it with a rope through the bottom of the cup. Decorate various decorations on the lantern theme with glue sticks, and now fix the upper part of the lantern with steel wires.

Such a beautiful and festive lantern was made. The fourth is a simple but interesting paper cup mobile phone.

Preparation materials: two paper cups and a cotton thread. Punch a hole in the center of the bottom of the paper cup, let the cotton thread pass through the bottom of the two paper cups, tie the knot and fix it, and connect the two paper cups to complete a paper cup mobile phone.

Simple as it is, the children have a good time.

Simple methods and diagrams of making small technology for primary school students

Purpose of 3D glasses experiment: 1. Understand the structure of the eyes and how the eyes see things. 2. Understand the common sense of protecting eyes. Experimental cognition: the principle of red and blue glasses: complementarity, also known as color difference 3D glasses.

The picture of the left projector passes through the red lens (left eye), and the red pixels removed during shooting will be automatically restored, thus producing a true color picture. When it passes through the blue lens (right eye), most of it is filtered out, leaving only a very dim picture, which is easily ignored by the human brain. On the contrary, the picture taken by the projector on the right side passes through the blue lens (right eye), and the blue pixels removed during shooting will automatically recover, resulting in a true color picture from another angle. When it passes through the red lens (left eye), most of it is filtered out, leaving only a dim picture, which is automatically filtered after the human eye reaches the brain. Experimental steps: 1. Understand the experimental equipment: double-sided red and blue lenses, paper frames, 4 small stereoscopic pictures and 2 large stereoscopic pictures.

2. Press the red and blue lenses on the frame (red and blue) and stick them with double-sided tape. 3. Observation and comparison: How do you feel when you look at the pictures provided with glasses? See how other ordinary pictures are different; Take off your glasses and put your hands in front of your eyes. Look at the blue film in the left eye, the red film in the right eye, and then look at the picture provided, which is not stereoscopic. Look at other pictures at the same time.

Bring your own glasses, look for "3D pictures, 3D videos" on the Internet, and feel a brand-new visual impact. (Moving the distance of the picture will have different effects) Knowledge expansion: the principle of stereoscopic glasses: the red and blue pictures superimposed in the picture are filtered by the red and blue lenses, so that the red picture enters the left eye and the blue picture enters the right eye. Although red and blue show the same content, there is a difference in relative displacement. This relative displacement difference between the left and right eyes further deceives the brain to form a feeling of 3D.

The most direct feeling of this 3D effect is that the objects in the picture seem to come out of the screen. Note: 1), 3D is the abbreviation of "3D graphics"; 2) This kind of picture is often specially processed, and not any picture can present stereoscopic vision.

How the eyes see things: the light emitted by external objects enters our eyes, and the eyes collect light through the pupils and then enter the retina. The retina can be imaged and inverted, and there are many light-sensitive cells in it, which can feel light. The retina transmits these signals to the optic nerve, and the optic nerve transmits these signals to the brain, and then you can see things.

The hand-made steps of teddy bears should preferably include detailed steps and cutting drawings.

To make a bear, we must first choose a favorite bear as a model among many bears of different colors and shapes. However, most customers will hesitate for a long time, because these bears are too cute to choose. After selecting the model, the clerk will find out the corresponding bearskin fabric and prepare the making tools for the customers. "Bear skin" is cut and shaped in advance, which saves a process. Isn't this service meticulous and thoughtful? Different shapes of cloth are placed in front of us. The next thing to do is to fold these flat fabrics in half, and then sew the edges together to form a three-dimensional part of the bear. Although this process sounds simple at first glance, it may be a piece of cake for clever girls who were baptized by cross-stitch two years ago, but it is obviously a bit difficult for clumsy boys. However, the average boy is also skilled in sewing the first leg, and the head, body, hands and the other leg are all successfully completed. After successfully sewing up all parts of the bear's body, you should fill them up, otherwise who would like a shriveled bear? The stuffing provided by this shop is the stuffing cotton for artists. If you do it yourself, you don't have to worry about meeting the legendary "black heart cotton". After filling all parts of the bear fat, sew all parts of the bear together, and the splicing work is completed. You have done needlework just now, so this job will naturally not be difficult for everyone. Don't think you will finish sewing the bear. The last step is to dress up the bear you made. The production process of a bear usually lasts for 4 hours, and the cost depends on the fabric and size. If imported fabrics are used, the smaller bear needs 2 18 yuan, and the bigger bear needs 288 yuan. If domestic fabrics are used, the cost of Bear and Bear is 120 yuan and 160 yuan respectively. In fact, the author carefully compared the two fabrics, and there is not much difference. Relatively speaking, it is more affordable to choose domestic fabrics.
