voxel-raycaster - Hardware accelerated voxel ray marching

  •        31

This project is an implementation of an experimental "from scratch" volumetric rendering engine. Using OpenCL this program is able to hardware accelerate Woo's Fast Voxel Traversal Algorithm which traverses through a Sparse Voxel Octree as described by Laine et al. Light is simulated using the Blinn-Phong shading model along with a recursive ray tracer style of shadow tracing. Individual voxels are also textured using a user provided texture atlas and voxel data. In order to build this project you must have Cmake, GLEW, SFML, and the OpenCL development libraries installed / downloaded. You're also going to need OpenCL compatable hardware that supports the cl_khr_gl_sharing extension. This project has, at some point, run on all three platforms: Windows (VS2017), Linux, and macOS. With a little bit of elbow grease it should still be able to compile and run on all these platforms.

sparse-voxel-octrees - CPU Sparse Voxel Octree Implementation

  •    C++

This project provides a multithreaded, CPU Sparse Voxel Octree implementation in C++, capable of raytracing large datasets in real-time, converting raw voxel files to octrees and converting mesh data (in form of PLY files) to voxel octrees. The conversion routines are capable of handling datasets much larger than the working memory, allowing the creation and rendering of very large octrees (resolution 8192x8192x8192 and up).

spatio_temporal_voxel_layer - A new voxel layer leveraging modern 3D graphics tools to modernize navigation environmental representations

  •    C++

This is a drop in replacement for the voxel_grid voxel representation of the environment. This package does a number of things to improve on the voxel grid package and extend the capabilities offered to the users, under a LGPL v2.1 license. Developed and maintained by Steven Macenski at Simbe Robotics. Leveraging OpenVDB, we have the ability to efficiently maintain a 3 dimensional voxel-representative world space. We wrap this with ROS tools and interfaces to the navigation stack to allow for use of this layer in standard ROS configurations. It is certainly possible to utilize this package without ROS/Navigation and I invite other competing methodologies to develop here and create interfaces.


  •    C++

SVO 2.0 and its extensions have been used to support various projects at RPG, such as our recent work on multiple camera SLAM, voxel map for visual SLAM and the tight-coupling of global positional measurements into VIO. We hope that the efforts we made can facilitate the research and applications of SLAM and spatial perception. The code is licensed under GPLv3.

semantic_slam - Real time semantic slam in ROS with a hand held RGB-D camera

  •    C++

Semantic SLAM can generate a 3D voxel based semantic map using only a hand held RGB-D camera (e.g. Asus xtion) in real time. We use ORB_SLAM2 as SLAM backend, a CNN (PSPNet) to produce semantic prediction and fuse semantic information into a octomap. Note that our system can also be configured to generate rgb octomap without semantic information. This project is released under a GPLv3 license.
