【摘要】：虛擬家裝系統(tǒng)是一種虛擬現(xiàn)實仿真系統(tǒng),其主要功能包括戶型設(shè)計、戶型裝修、戶型瀏覽及其它戶型相關(guān)的輔助功能。 本文的主要工作分為戶型虛擬設(shè)計和戶型虛擬裝修這兩部分。在戶型設(shè)計方面,按照戶型的設(shè)計步驟來描述：墻體的繪制,不同墻體的連接,房間的形成及戶型的構(gòu)造。在戶型設(shè)計完成后,需進行戶型裝修。戶型裝修包括墻體、地板及天花板的裝修,主要是在這些對象上鋪貼如墻紙、瓷磚及木板等材料紋理,其中墻體裝修還包括門窗的放置。同時也可以對戶型進行軟裝修,即在戶型中擺設(shè)家具模型。最后經(jīng)過設(shè)計與裝修可以得到理想效果的戶型。 同時,本文還對裝修過程中使用到的材料紋理進行了比較深入的研究。采用灰度共生矩陣分析了墻紙紋理的周期性特征,并提出了紋理周期單元的自動提取算法。使用提取的周期單元作為戶型裝修的墻紙紋理,不僅減少了紋理圖片的內(nèi)存占有同時也保證了紋理鋪貼效果的連續(xù)性。對于瓷磚紋理,主要研究了多個瓷磚材料拼貼問題。本文采用的方法：先計算鋪貼規(guī)則(幾何規(guī)則)的周期性,然后通過渲染到紋理的技術(shù)形成周期性的幾何紋理,最后將幾何紋理映射到目標區(qū)域。這種方式也能保證瓷磚紋理之間的連續(xù)性。同時,討論了木板紋理的鋪貼效果更真實化的情況。這些紋理問題的研究與解決方案的設(shè)計使得虛擬場景的材料裝修更加真實化。
[Abstract]:Virtual home decoration system is a virtual reality simulation system. Its main functions include household design, decoration, browsing and other auxiliary functions. The main work of this paper is divided into two parts: virtual design and virtual decoration. In the design, according to the design steps: the drawing of the wall, the connection of different walls, the formation of the room and the construction of the household. After the completion of the household design, it is necessary to house decoration. Family decoration includes wall, floor and ceiling decoration, mainly in these objects such as wallpaper, tile and wood materials texture, including wall decoration also includes the placement of doors and windows. Also can carry on the soft decoration to the household type, namely furnishes the furniture model in the household type. Finally through the design and decoration can get the ideal effect of the Huxing. At the same time, the texture of the material used in the decoration process is studied in depth. The periodic feature of wallpaper texture is analyzed by using gray level co-occurrence matrix, and an automatic extraction algorithm of texture periodic unit is proposed. Using the extracted periodic unit as the wallpaper texture not only reduces the memory of the texture image but also ensures the continuity of the texture paving effect. For tile texture, the problem of multiple tile materials collage is mainly studied. The method used in this paper is to calculate the periodicity of the layering rules (geometric rules), then form periodic geometric textures by rendering to textures, and finally map geometric textures to target regions. This approach also ensures continuity between tile textures. At the same time, the more realistic effect of plank texture is discussed. The research of these texture problems and the design of the solution make the material decoration of virtual scene more realistic.
