Description

Technical Field

[0001] This invention belongs to the field of virtual and reality technology application technology, specifically involving an immersive exhibition platform for traditional Chinese painting and calligraphy in a VR environment. Background Technology

[0002] In the realm of traditional culture and art, traditional Chinese painting and calligraphy, as treasures of the Chinese nation, carry profound historical and cultural significance. However, within the existing technological framework, the display and dissemination of these traditional artworks still face many challenges and shortcomings.

[0003] Traditionally, the display of traditional Chinese paintings and calligraphy works has mainly relied on physical exhibitions and galleries. This method of display is not only limited by geography and time, but also poses a significant risk to cultural heritage as physical works are easily damaged during preservation, transportation, and display. Furthermore, the interactive methods of physical exhibitions are relatively limited, making it difficult to meet the needs of modern audiences for diverse and personalized viewing experiences.

[0004] With the development of digital technology, although there have been some attempts to digitize traditional Chinese paintings and calligraphy, these attempts often remain at the level of simple image scanning and copying, lacking a fine reproduction of the details and textures of the works. Furthermore, when these digital works are displayed, they often lack in-depth interaction with the audience, failing to allow viewers to deeply understand the artistic connotations such as brushstrokes and ink variations, thus affecting the audience's viewing experience and learning outcomes.

[0005] Therefore, existing technologies have significant shortcomings in the digital display and dissemination of traditional Chinese paintings and calligraphy, necessitating a more advanced and comprehensive technological solution. The introduction of virtual reality (VR) technology offers a new approach and method for addressing this issue. Through VR, not only can traditional Chinese paintings and calligraphy be digitally reproduced, preserving the essence of traditional art, but interactive methods also allow viewers to gain a deeper understanding of the artwork's meaning and details, thereby bridging the gap between traditional art and modern audiences and strengthening the emotional connection between users and artworks.

[0065] Example 2:

[0066] refer to Figure 1 As shown, the simulation construction includes exhibition hall layout, lighting layout, wall material, and space expansion;

[0067] The lighting layout is calculated from the light intensity, and its expression is:

[0068] Lo(p,wo)=Le(p,wo)+∫ Ω fr(p,wi,wo)Li(p,wi)(n,wi)dwi

[0069] Lo(p,ωo): The intensity of the light reflected from point p in the direction ωo;

[0070] Le(p,ωo): The intensity of the light emitted by point p in the direction ωo;

[0071] fr(p,ωi,ωo): The bidirectional reflection distribution function (BRDF) of point p;

[0093] The above formula ensures that the ink details remain clearly visible when users zoom in and out of calligraphy works, thereby enhancing users' visual experience and understanding of the artistic details of traditional Chinese paintings and calligraphy works.

[0094] Specifically, the user interest trend is predicted using a collaborative filtering recommendation algorithm. Based on the user's browsing history and interaction data, the algorithm predicts the calligraphy or traditional Chinese painting works that the user may be interested in. The expression for the collaborative filtering recommendation algorithm is as follows:

[0095]

[0096] Where Ru,i: user u's predicted rating for exhibit i;
