Photoshop Basics Tutorial: Stereo Perspective in Graphic design

Introduction:
Some friends like to use PS to do some stereo objects, or draw some 3-dimensional scenes, but suffer form inaccurate or no strong visual impact. This is not a good sense of the three-dimensional relationship, especially the basis of perspective, for us without 3ds Max software Photoshop enthusiasts to learn the perspective of the important.

I remember the University of engineering drawing when learning a little ~ Although forget a lot, but the current design of the application is quite helpful.
The next time to draw a strong perspective on things, you can use the brush to play a manuscript ~ so it will not be too shape.

The meaning of perspective chart
The design needs to use the diagram to express the idea. In advertising art, architecture, interior design, sculpture design, decorative design and industrial design, as well as other related fields, are through the expression of the designer's idea conveyed to the user, that is, through the picture to communicate.

Perspective is the most important of any person who is engaged in performing art design. Whether you are engaged in art, architecture, interior design, you must master how to draw perspective, because it is the basis of all the drawings. Perspective helps to form true imagination. And it's based on perfect cartography.

Perspective painting, is the building of the plane, façade or interior of the expansion diagram, according to the design information, painting into a picture has not yet become an entity. The three-degree space will be transformed into a three-dimensional picture of the two-degree space drawing techniques, and can truly reproduce the designer's expectations.

Perspective painting, not only to pay attention to material sense, for the color of the screen composition, composition and other issues, perspective painting techniques in the drawing techniques have a great responsibility, because excellent perspective painting beyond the surface of the building description, with the other side of the outstanding painting character.
In the architectural, interior design of the performance of the painting, the space must be accurate, because the distortion of the space performance will give designers and users to create illusion, and the relevant parts appear uncoordinated.

People who often draw perspective paintings are not necessarily completely faithful to the drawing process of perspective drawing, most of them using simple methods. This method not only saves time, and can improve the visual effect, but it needs to be trained by painting and perspective skills to be able to do so. It needs to the stereo modelling of the building, interior space has deep understanding and grasp.

Perspective painting and painting, carving different, can not be completed alone with the pure form, can not see the perspective of the painting as a specialized technology, but only to learn its skills on the idea that it is done, must be closely with the original design plan, master the design intent, so as to fully represent the designer's ideas.

second, perspective chart
Perspective is the perspective projection, between the object and the position of the viewer, imagine that there is a transparent plane, the viewer of the object each bursts out of sight, and this plane intersection point of connection, formed by the figure, called perspective. Focus on the point of view.

The perspective is within the visual range of the human eye. In perspective, because the projection line is not parallel to focus on the point of view, so show the size of the object, not the real size, there are nearly large and far small characteristics. Shape, because of the angle factor, rectangular or square is often drawn into irregular quadrilateral, right angle drawn into acute or obtuse angles, four sides are not equal. The shape of a circle is often displayed as an ellipse (Figure 01, 02).

Perspective Terminology:
P. P. The picture is assumed to be a transparent plane;
G P. The ground plane of the floor building is horizontal;
G L The intersection of the horizon floor and the picture;
E. Point of view of the human eye;
H. P. The horizontal plane at which the height of the human eye is seen;
H. L Visual flat line and picture of the intersection line;
H. The distance from the high point of view to the ground;
D The vertical distance from the visual angle to the picture;
C V. The point of view is the vertical line of the visual center, and the intersection of the perpendicular and the horizon;
S. L The line of sight and the points on the object;
C L The centerline of the center line over the screen is perpendicular to the visual line.
