摘 要: 当代油画创作过程中以其独特表现力以及表达手法受到大众的追捧,但当代油画受到创作形式以及创作工具的限制,降低了油画层次感的表达能力,为此,提出基于三维视觉的当代油画虚拟创作形式。对油画笔径以及关键帧进行确认,对过度帧插值进行确定,以三维视觉的呈现方式实现油画的虚拟创作。通过模拟实验结果可以看出,提出的创作方法能够有效地表达当代油画艺术风格,并增加层次感,实现三维虚拟视觉呈现。

Abstract: The creation process of contemporary oil painting is welcomed by the public because its unique expression skill and expressing method. But the contemporary oil painting is limited by creation form and creation tool, which can reduce its layered presentation skill. Therefore, a three?dimensional (3D) vision based virtual creation form of contemporary oil painting is put forward. The stoke of oil painting brush and key frame are confirmed, and the excessive frame interpolation is established to realize the virtual creation of oil painting in the presentation form of 3D vision. The simulation experimental results show that the proposed creation method can express the artistic style of contemporary oil painting effectively, increase the layered expression, and realize the 3D virtual visual presentation.
Keywords: three?dimensional vision; contemporary oil painting; virtual creation; frame interpolation; stroke path calculation; layered expression

三维虚拟视觉构建方式(Virtual Reality Modeling Lan?guage,VRML)是一种用来描述交互式三维视觉呈现的方式。三维视觉技术即VRML,是利用三维扫描以及关联节点数据对想要呈现的内容进行多方位、多角度的虚拟呈现。当代油画创作中,表达手法以及绘画风格已经在艺术作品中占据很重的地位,但是当代油画作品受到绘画方式以及绘画工具的限制,作品中缺少层次的质感[1],并且油画作品的保存方式非常严苛,极易发生破损和褪色,针对上述问题,本文提出基于三维视觉的当代油画虚拟创作形式。利用三维视觉技术对油画笔径以及绘画关键帧进行确认,保证基本绘画风格,对过度帧插值进行优化计算,保证当代油画创作中的风格和写实性。通过设计的仿真试验,有效验证本文提出的创作方法,能够增加油画作品的层次感,并通过数据形式保存,有效地延长了油画的寿命。……
