Problems solved by technology
[0006] Among the current brushstroke models of various styles, the simulation of oil painting style strokes is relatively the most difficult, for three reasons: first, the oil painting stroke model not only contains color texture and shape information, but also a height information (mainly expressing the thickness of oil painting strokes) information); the second is that the physical process of oil-water mixing is relatively complicated, and the thickness and color fusion of oil paint brushes are much more complicated than the watercolor brush model; the third is that there are many types of brush strokes, including thin coating, thick coating, dry Wiping, loose coating, cover dyeing, knife scraping, etc.

Embodiment Construction
[0034] The present invention sets up the method embodiment of oil painting brush sample storehouse, and it comprises the following steps:
[0035] Step (1), scanning the picture drawn by the oil painting feature brush and inputting the obtained image into the computer; the picture drawn by the oil painting feature brush at least includes: point brush picture, linear brush picture, block brush picture and textured brush drawings.
[0036] In this step, a professional artist draws oil painting brushes of various shapes on clean white paper, and then selects 8 pictures drawn by oil painting characteristic brushes from the drawn brushes, and divides these pictures into four categories according to the shape and texture of the brushes : Point brushes (5 pieces), line brushes, block brushes, and texture brushes (such as figure 1 shown).
[0037] Step (2), the step that computer processes input image, it comprises:
[0038] A. The steps of obtaining the opacity map and the pigment...

The present invention relates to the method for setting up the oil painting brush sample storehouse, it comprises the following steps: step (1) scanning the picture drawn by the oil painting characteristic brush and inputting the obtained image into the computer; step (2) the step that the computer processes the input image, It comprises the step of obtaining opacity map and paint thickness map; Step (3) sets up the step of oil paint brush sample library; In the storage structure table of each oil paint brush sample in the oil paint brush sample library at least includes: input image, The opacity map of the image, the paint thickness map of the image. The realism of the oil painting style of the oil painting simulated by calling the oil painting brush sample library established by the method of the present invention is greatly improved.
Description
technical field [0001] The invention relates to the technical field of computer-based oil painting, in particular to a method for simulating brush strokes based on computer-based oil painting non-realistic rendering, in particular to a method for establishing a computer-based oil painting brush sample library. Background technique [0002] Oil painting simulation is a style of non-photorealistic simulation technique. The art styles of non-photorealistic rendering simulation technology include sketch, watercolor painting, oil painting, traditional Chinese painting, pen pastel and so on. Most of the current existing research is mainly aimed at the simulation of artistic stylized material models, mainly including various strokes, physical models of paper, and the interaction between simulated strokes and paper. For example, pencil models and brush models have been successfully applied to sketches, Chinese paintings and Watercolor painting, and achieved a better simulation effe...
