Description

Auxiliary tool for drawing three-dimensional view

Technical Field

The utility model relates to an appurtenance for drawing three-dimensional view, especially an appurtenance for drawing three-dimensional perspective.

Background

In the social life, people often need to practice drawing stereoscopic views, particularly drawing perspective views, in the process of learning and practicing free-hand drawing.

The perspective view is a perspective view established by three elements of an observer (person drawing), an object (landscape) and a picture, assuming that the observer (person drawing) stands at a fixed position and a picture is provided between the observer (person drawing) and the object (landscape), each line of sight directed from the viewpoint of the observer (person drawing) to each part of the object (landscape) has an intersection with the picture, and the set of intersections constitutes the perspective view. Therefore, drawing a perspective view means that key points on a picture are obtained according to a certain rule and then are connected into a graph, and at this time, the drawing paper is equivalent to the picture. However, the normal freehand drawing does not need to strictly draw according to the drawing rule, and the vanishing point position and the direction and the size of the auxiliary line are determined freehand on the drawing paper by visual inspection, so that the vanishing point position and the direction and the size of the auxiliary line approximately accord with the drawing rule, and the drawing method for strictly drawing the perspective view is well documented in many books, for example: the "practical stereography" published by mechanical industry Press 1997, 12 months, the knowledge in this section is therefore of common general knowledge and will not be described in detail here.

When a drawing perspective is exercised, an auxiliary line is often required to be drawn on a drawing paper so as to facilitate a plotter to establish a correct perspective relation on the drawing paper and then finish a drawing, but a beginner who just starts to contact the drawing often cannot draw the auxiliary line accurately by hands due to unskilled drawing skills, particularly the auxiliary line which is intersected at a vanishing point is more obvious if the number of the auxiliary lines which are intersected at the vanishing point is more, and further the drawing effect of subsequent views or drawings is influenced. The intersecting auxiliary vanishing point line is a straight line extending from the contour line of the drawn object to the vanishing point.

Detailed Description

For a better understanding of the present invention, reference will now be made in detail to the embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Here, the auxiliary thread simulation tape 104 is a flexible thread which is stretched and straightened into a straight shape by a hand of a painter in use, and is drawn into a straight line in accordance with a state of use in the drawings of the present specification for the sake of illustrative intuition and drawing simplicity.

See fig. 1, fig. 2, fig. 3, fig. 4, fig. 5, fig. 6, fig. 7, fig. 8, fig. 9.

A long groove 201 is formed on the upper surface of a main scale 101 of the stereoscopic view drawing auxiliary tool, a long through groove 202 is formed at the bottom of the long groove 201, a lug 203 is formed on one surface of the main scale 101, and a hole 204 is formed in the lug 203.

The auxiliary ruler 102 of the stereo view drawing tool is provided with a through hole 205 and a boss 206.

The main scale fixing clamping plate 103 of the stereoscopic drawing auxiliary tool is provided with a lug 207, and the lug 207 is provided with a through hole 208.

The hole 204 of the main scale 101 is aligned with the hole 208 of the main scale fixing clamping plate 103 and the spiral center of the elastic element 106, the pin shaft 105 passes through the hole 204 of the main scale 101, the hole 208 of the main scale fixing clamping plate 103 and the spiral center of the elastic element 106 at the same time, the main scale 101, the main scale fixing clamping plate 103 and the elastic element 106 are connected together through the pin shaft 105,

the movable auxiliary ruler 102 is installed in the long groove 201 on the main ruler 101, the movable auxiliary ruler 102 can slide in the long groove 201, one end of the auxiliary line simulation flexible ruler 104 is fixedly installed in the through hole 205 on the auxiliary ruler 102, and the specific measures can be that the diameter size of the auxiliary line simulation flexible ruler 104 is slightly larger than the inner diameter size of the through hole 205 on the auxiliary ruler 102, and interference fit is adopted, so that the purpose of fixed installation is achieved.

When the secondary scale 102 moves in the elongated groove 201 of the main scale 101, it is obvious that the center point of the through hole 205 of the secondary scale 102 moves together, and the center point of the through hole 205 of the secondary scale 102 forms a motion track, and the motion track is a straight line track.

In particular, the main scale 101 is first determined in position on the drawing board, and the stereoscopic view drawing auxiliary tool is mounted in position on the drawing board using the main scale fixing plate 103. The principle of determining the proper position of the main scale 101 on the drawing board is that, first, the position of the perspective view flat line is determined on the drawing paper (i.e. the flat line is drawn), then, according to the drawing rule of the perspective view, the position of the vanishing point of the perspective view is determined on the flat line by combining the object to be drawn, then, the main scale 101 is attached to the drawing paper, the motion track formed by the center point position of the through hole 205 of the auxiliary scale 102 is made to coincide with the flat line, after the position of the main scale 101 is determined, the stereoscopic view drawing auxiliary tool is fixed on the drawing board by using the main scale fixing clamp plate 103, and after the position of the main scale 101 is determined, the auxiliary scale 102 is moved so that the center point of the through hole 205 on the auxiliary scale 102 coincides with the vanishing point of the perspective view to be drawn. At this time, the plotter draws the auxiliary line simulation tape 104 tight and stuck to the drawing board surface with one hand, then turns the auxiliary line simulation tape 104 to an appropriate angle (the appropriate angle is determined according to the drawing rule of the perspective view, which is a part of common knowledge), and the position of the auxiliary line simulation tape 104 is the position of the auxiliary line of the perspective view (i.e. the parallel line on the perspective object), and then draws the auxiliary line with the other hand by holding the pen, and so on, and draws other auxiliary lines. If the view is a two-point perspective view (that is, the view has two vanishing points), an auxiliary line meeting at one vanishing point may be drawn, and then the movable sub-ruler 102 is moved to the second vanishing point, and then the auxiliary line meeting at the vanishing point is drawn. The drawing can be performed alternately according to the drawing requirement.

See fig. 10, 11.

Fig. 10 and 11 are perspective view drawing auxiliary tools in which two movable auxiliary scales are provided on a main scale and auxiliary line simulation tapes are respectively fixed to the two movable auxiliary scales, and the structure is substantially identical to that of the perspective view drawing auxiliary tools shown in fig. 1, 2, 3, 4, 5, 6, 7, and 8, except that two movable auxiliary scales 102 are installed on the main scale 101 of the perspective view drawing auxiliary tool shown in fig. 10 and 11, and simultaneously, auxiliary line simulation tapes 104 are respectively fixed to the through holes 205 of the two movable auxiliary scales 102, which has an advantage that, if the drawn perspective drawing is two-point perspective (the perspective drawing has two vanishing points), it is possible to respectively align the centers of the through holes 205 of the movable auxiliary scales 102 with different vanishing points, and then respectively draw a desired auxiliary line (i.e., a parallel line on a perspective object) according to the foregoing method, compared to an embodiment in which only one auxiliary scale is provided on the main scale, there is an advantage that, when drawing an auxiliary line of a two-point perspective drawing, only one auxiliary scale is required to be repeatedly installed at a position.

See fig. 12.

Fig. 12 shows that two movable sub-rulers 102 are installed on the main ruler 101, and both ends of an auxiliary line simulation tape 104 are respectively fixed in through holes 205 on the two movable sub-rulers 102.

It should be noted that the present invention is not a strict formal drawing tool and instrument, but is only used to help the beginner to visually understand on the drawing paper as soon as possible and draw the auxiliary lines of the perspective drawing (i.e. the parallel lines on the perspective object) relatively accurately, and on the basis of this, the concept of perspective drawing is established.

The stereoscopic viewing image rendering aid of the present invention may also make modifications or substitutions and variations obvious to those of ordinary skill in the art.
