摘 要: 當代油畫創作過程中以其獨特表現力以及表達手法受到大眾的追捧,但當代油畫受到創作形式以及創作工具的限制,降低了油畫層次感的表達能力,為此,提出基于三維視覺的當代油畫虛擬創作形式。對油畫筆徑以及關鍵幀進行確認,對過度幀插值進行確定,以三維視覺的呈現方式實現油畫的虛擬創作。通過模擬實驗結果可以看出,提出的創作方法能夠有效地表達當代油畫藝術風格,并增加層次感,實現三維虛擬視覺呈現。

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

三維虛擬視覺構建方式(Virtual Reality Modeling Lan?guage,VRML)是一種用來描述交互式三維視覺呈現的方式。三維視覺技術即VRML,是利用三維掃描以及關聯節點數據對想要呈現的內容進行多方位、多角度的虛擬呈現。當代油畫創作中,表達手法以及繪畫風格已經在藝術作品中占據很重的地位,但是當代油畫作品受到繪畫方式以及繪畫工具的限制,作品中缺少層次的質感[1],并且油畫作品的保存方式非常嚴苛,極易發生破損和褪色,針對上述問題,本文提出基于三維視覺的當代油畫虛擬創作形式。利用三維視覺技術對油畫筆徑以及繪畫關鍵幀進行確認,保證基本繪畫風格,對過度幀插值進行優化計算,保證當代油畫創作中的風格和寫實性。通過設計的仿真試驗,有效驗證本文提出的創作方法,能夠增加油畫作品的層次感,并通過數據形式保存,有效地延長了油畫的壽命?!?br>
