Drawing pencil box based on the principle of two-point perspective (angular perspective)

Draw a pencil box based on the principle of two-point perspective (angle perspective) as follows:

First kind

1. First, you need to draw an oblique rectangle, and then draw a supplementary picture, drawing its right and bottom.

2. Then slowly draw a line consisting of two inner corners, the upper left corner and the lower left corner.

3. Then draw the flip of the pencil case to the left according to the left edge line of the drawn box.

4. Draw a pencil in the pencil box, and pay attention to add some detail lines on the pencil.

5. Paint the whole pencil box red, and the inside of the box and the inside of the flip cover are darker.

6. Finally, paint the pencil shaft in striped blue and the nib in black, and a simple pencil box will be drawn.

The second type

1. Draw the lid of the pencil case first, and then draw the plane outline of the bottom after drawing the central axis.

2. After drawing the side edge line at the bottom, draw a line on the inside of the cover to form the three-dimensional sense of the pencil case.

3. After the upper and lower edges of the outside of the pencil case are all painted yellow, the inside of the cover is painted orange.

4. Finally, paint orange on the inside of the bottom, and properly emphasize the color shadow to draw a simple pencil case.

Perspective refers to the visual phenomenon produced by objects in space, that is, the image formed by objects on the retina.

Perspective principle is to explain how to represent objects in three-dimensional space on two-dimensional plane by analyzing the relative position of objects and viewpoints, the angle of light projection, the size and shape of objects, etc.

Two types of perspectives:

1, Parallel perspective means that a set of planes of an object are parallel to the observer's visual field, and the object presents the effect of a cube.

2. Angle perspective means that the plane of the object is not parallel to the observer's visual field, and the object presents a diamond effect.

The usage of perspective:

Mainly in painting and photography, by adjusting the relative position of the object and the viewpoint, the projection angle of light, the size and shape of the object and other parameters, the projection of the object on the two-dimensional plane in three-dimensional space can be expressed.

1, in painting:

The application of perspective can make the picture have a sense of depth and three-dimensionality, and let the audience feel the sense of space and form better. Common perspective methods include one point perspective, two point perspective and three point perspective.

One-point perspective refers to the perspective with only one vanishing point (vanishing point), which is suitable for drawing small objects. The perspective changes little, but it should reflect the position of the vanishing point.

Two-point perspective refers to the perspective with two vanishing points, which is suitable for drawing larger objects and can represent multiple faces of the objects.

Three-point perspective refers to the perspective with three vanishing points, which is suitable for drawing objects with large height and can represent multiple faces and heights of objects.

2. In photography:

The application of perspective can control the composition and depth of photos by adjusting the lens and shooting angle. For example, using wide-angle lens and low-angle shooting can show the grandeur and depth of the scene; By using telephoto lens and high-position shooting, the details and shapes of the scene can be expressed.

In a word, the application of perspective can make objects present visual effects in three-dimensional space on two-dimensional plane, enhance the depth and three-dimensional sense of the picture, and make the audience feel the beauty and shape of the picture better.
