论文《Learning a HierarchicalLatent-Variable Model of 3D Shapes》表明,将输入映射到单个潜在表示的编码器不能提取丰富的结构,因此可能导致模糊的重构。为提高重建质量,该模型引入了更复杂的内部变量结构,其目的是鼓励对潜在特征检测器的分层排列进行学习。 该方法从一个全局隐变量层开始,该层被硬连接到一组局部隐变...
Building such a large-scale dataset, however, is highly challenging; existing datasets either contain only synthetic data, or lack precise alignment between 2D images and 3D shapes, or only have a small number of images. Second, we calibrate the evaluation criteria for 3D shape reconstruction ...
We investigate the problem of learning a probabilistic distribution over three-dimensional shapes given two-dimensional views of multiple objects taken from unknown viewpoints. Our approach called projective generative adversarial network (PrGAN) trains a deep generative model of 3D shapes whose projections...
I want to generate flat surfaces what arbitrary shapes. For example, like those shapes generated in "webgl_geometry_shapes.html". I followed the "webgl_geometry_shapes.html" example: create THREE.Shape(); then call the extrude() method of my THREE.Shape object; finally create THREE.Mesh o...

For IoU, we first find the bounding box of the object with a threshold of 0.1, pad the bounding box into a cube, and then use trilinear interpolation to resample to the desired resolution (32 x 32 x 32). Some algorithms reconstruct shapes at a resolution of 128 x 128 x 128. In this...
Most lessons from this section (and the advanced rendering section) fall within one of these categories.

but I was surprised that we could design / "model" more than simple extruded shapes with sharp 90° edges.In my photo above, the test objects I created do not have sharp edges, and maybe even the starting reference image at the beginning of the discussion with the 3D letter "D...
We present a new pipeline for holistic 3D scene understanding from a single image, which could predict object shape, object pose, and scene layout. As it is a highly ill-posed problem, existing methods usually suffer from inaccurate estimation of both shapes and layout especially for the clutter...
