Core Viewpoint - The article discusses the advancements in AI 3D generation technology, highlighting the introduction of a new evaluation system called Hi3DEval, which aims to provide a comprehensive assessment of 3D content generation quality through a multi-layered approach [3][8][28]. Group 1: Hi3DEval Evaluation System - Hi3DEval is a new hierarchical automatic evaluation system for 3D content generation, developed in collaboration with several universities, addressing the limitations of traditional evaluation methods [3][8]. - The evaluation framework consists of three levels: object-level, part-level, and material-subject, allowing for a detailed analysis of 3D generation quality [5][8][9][15][17]. - The first 3D generation leaderboard has been published on HuggingFace, featuring 30 mainstream and cutting-edge models, covering both Text-to-3D and Image-to-3D tasks [6][21]. Group 2: Evaluation Dimensions - Object-level evaluation focuses on five dimensions: geometric plausibility, geometric detail, texture quality, geometric-texture coherence, and prompt-3D consistency [9][10][12][14]. - Part-level evaluation allows for a more granular assessment of specific components, such as chair legs or armrests, identifying defects in local structures [15][16]. - Material-subject evaluation assesses surface visual and physical properties across four dimensions: detail and complexity, color and saturation, consistency and artifacts, and material plausibility [17]. Group 3: Leaderboard and Industry Impact - The leaderboard provides a standardized assessment of models under uniform conditions, ensuring fairness and referenceability in the evaluation results [21][28]. - The introduction of Hi3DEval aims to establish a systematic and transparent quality evaluation standard for 3D content, facilitating better comparisons and advancements in the industry [28].

Core Viewpoint - VAST, an AI 3D generation model company, has recently completed a multi-million dollar Pre A+ round of financing, aiming to revolutionize 3D modeling through AI technology, significantly reducing the time required for 3D modeling from 15 hours to just 6 minutes [4][18]. Company Overview - VAST was founded in March 2023 and gained initial attention with its open-source project Wonder 3D on GitHub, which allows the generation of 3D models from 2D images [4]. - The company has launched its first product, Tripo, which generates 3D models using both text descriptions and images, and has recently released Tripo Studio, the world's first AI 3D workstation [4][24]. Product Development and Market Strategy - VAST's strategy involves a phased approach to user engagement, starting from professional users to casual creators, and eventually reaching general consumers [8][9]. - The company aims to create a "3D version of Meitu" that allows users to easily and freely create 3D content, with a timeline of 3 to 10 years for achieving widespread adoption [9][10]. - VAST has focused on developing its technology to a state-of-the-art level before moving towards productization and commercialization [11][12]. User Engagement and Growth - After the launch of Tripo Studio, the user payment rate increased fourfold within a week [18]. - The company has a diverse user base, including over 35,000 small and medium-sized clients and more than 700 large clients, relying on user satisfaction and word-of-mouth for growth [19]. Competitive Landscape - VAST has established itself in the AI 3D generation space ahead of larger companies, which are now beginning to recognize the potential of this technology [12][26]. - The company believes that the true competitive barrier lies in the ability to believe in the potential of AI 3D generation before it becomes mainstream [26]. Vision and Mission - VAST's slogan, "For the advancement of civilization and the creation of happiness for humanity," reflects its commitment to enhancing individual experiences through AI-generated 3D content [50][52]. - The company aims to democratize 3D content creation, allowing individuals to express their creativity and share their stories through various platforms [50][52].
