DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drawing information processing apparatus, and more particularly, to an information processing apparatus which realizes the same action as when actually drawing a picture using a brush, paint (paint) and paper. Normally, factors that greatly affect the finish of the work, such as the speed at which a person moves the brush at the time of drawing, the pen pressure applied to the brush at that time, and the characteristics of the painting material used when drawing, are reflected as much as possible. The present invention also relates to a drawing information processing apparatus capable of faithfully simulating a drawing act itself and a work based on the drawing act.

2. Description of the Related Art When drawing using an information processing apparatus, the speed at which the brush is moved (moved), the pressure applied to the brush, and the characteristics of the painting material used are taken into consideration. It is necessary to be able to create works that reflect the world imagined by the artist as faithfully as possible.
In making a work using a conventional drawing information processing apparatus, it was almost impossible to make use of the writer's technique and the characteristics of the painting materials. That is, the conventional drawing information processing apparatus includes, as elements of a writer's drawing action, generation of a trajectory of an input unit used as a brush, selection of a paint color, a brush thickness, a fill pattern provided by a system, and the like as elements. And no other information was accepted. As a result, it was difficult to create a writer's personality in a work only from within this information.

For example, in an actual writer's drawing act, the writer's technical characteristics such as a change in the moving speed of the writer's brush and the pressure applied to the brush, and the characteristics of the paint material such as a brush, paint, and a material to be drawn. It is known that the difference causes various differences in the content of the produced work. On the other hand, in drawing using an information processing device, as long as the range of information related to drawing is limited as described above, it is difficult to create a work that reflects an actual writer's work.

[0004] It is an object of the present invention to provide a drawing information processing apparatus capable of creating a work that reflects the difference in the drawing skill and the drawing material used by the writer as much as possible, which is an element related to the drawing action of the writer. It is in.
