在2.0版本5大模型开源一个月后,4月23日,腾讯控股(00700)混元3D生成模型正式发布2.5版本新模型,建模精细度上大幅提升,实现超高清的几何细节建模,表面更平整、边缘更锐利、细节更丰富,有效几何分辨率达到1024,从标清升级到了高清画质。
在模型架构上,混元 3D v2.5 也实现了全面升级,总参数量从1B提升至10B,有效面片数增加超10倍。混元3D AI创作引擎全面更新至v2.5模型底座,同时免费生成额度翻倍,提升至每天20次。混元3D生成API也已正式上线腾讯云,面向企业和开发者开放。
腾讯混元3D新版本支持4K高清纹理和细粒度bump凹凸贴图,能够模拟物体表面高低起伏的视觉效果。同时,混元 3D在业界率先实现多视图输入生成PBR模型,显著提升生成质感和真实感。
此外,为满足专业创作者需求,混元3D v2.5优化了骨骼蒙皮系统,支持非标准姿态下的自动骨骼绑定和自动蒙皮权重赋值,大幅提升3D动画生成效率。3D生成工作流功能也进一步升级,提供文生/图生3D智能减面模型、多视图生3D模型等专业管线模板。
腾讯混元积极拥抱开源生态,混元3D 1.0、2.0基础模型及基于2.0 模型的加速、多视图和轻量级模型均已开源,Github总 star 数超 1.2 万,不断丰富 3D AIGC 社区。
