3D DeepDream 也以类似的方式执行。这两个应用程序都是通过Nueral Render将 2D图像空间中的信息流入 3D 空间来实现的。 参考资料: Neural 3D Mesh Rendererarxiv.org/abs/1711.07566 https://hiroharu-kato.com/publication/neural_renderer/hiroharu-kato.com/publication/neural_renderer/ ...
[CV] HybridNeRF: Efficient Neural Rendering via Adaptive Volumetric Surfaces http://t.cn/A6lU27gy 引入HybridNeRF,一种混合表面-体表示方法,能以较少的样本实现高质量的渲染。与传统的体渲染方法相比...

Video 1: We render lidar-scanned point clouds using pointersect. Pointersect enables us to move within point clouds captured by lidars, relight, and interact with the virtual scenes directly without retraining. The scenes are very different from the training dataset (which is shown at the bottom...
2.2 Volumn render(体渲染) 在这里插入图片描述 体渲染(Volume Rendering)是一种用于可视化三维体积数据的技术,通常应用于医学成像、科学可视化和计算机图形学等领域。体渲染的目标是生成逼真的图像,呈现出体积内部的结构和特征。 NeRF使用渲染方式的正是基于体渲染技术。==由于体渲染全程都是可微分的,就可以用神经网络...
Given high-quality scene specifications,Classic Rendering Methodscan render photorealistic images for a variety of complex real- world phenomena. Moreover, rendering gives us explicit editing control over all the elements of the scene—camera viewpoint, lighting, geometry and materials. However, building...
Neural Texture + Deferred Render的算法框架 大道至简,大体思路其实很简单,由下图所示在传统的光栅化流程中,给定一个相机参数,根据物体的3D几何表示(三角面片)、UV映射以及Texture(存储着RGB颜色值的纹理贴图)边可以得到一张渲染图像。如果我们将传统渲染管线中Texture存储的内容由RGB颜色值换成一组隐式表示latent code...

所以PIRender可以依据source image和运动描述符p来生成target. The Mapping Network 首先将运动描述符p映射到z,z=fm(p)z=fm(p),fmfm就是映射网络 z通过affine transformation来产生y=(ys,yb)y=(ys,yb), 来通过AdaInN进行后续操作. 每个feature mapxixi首先normalized 然后用ys,iys,iscaled和yb,iyb,ibiased....
Our solution to this problem is to learn a compact image-based rendering of the original 3d character, conditioned directly on the rig parameters. Our idea is to render the character in many different poses and views, and to train a deep neural network to render high resolution images, from...
