Fine-Grained VR Sketching: Dataset and Insights

This is the code project for Fine-Grained VR Sketching: Dataset and Insights published on 3DV 2021.

Paper Link: [Paper] [Supplemental]

SkethchyVR dataset are avaiable at Dataset webpage and Google Drive (point cloud only).

Here are some samples of the shape sketch pairs in SkethchyVR:

VR Sketch interface

The dataset used in this project is collected with a VR sketching interface called SketchyVR which allow participants to sketch inmmersively using VR headsets and handles like Oculus Rift.

Sketch filtering

Demonstration on filtering the original sketches: tools/Filter original sketch.ipynb

Point cloud sampling

Once filtering the original VR sketches, point clouds for training are sampled form the filtered sketch. Script for sampling from sketches and meshes: tools/gen_pointcloud.py

Point cloud Rendering

Render image for point cloud files: tools/vis_pc_mitsuba.py

Install MITSUBA first and then replace the PATH_TO_MITSUBA2 with your path.

Models for 3D shape retrieval
