LiDAR VR Viewer

LiDAR VR Viewer is dedicated to the visualization of point clouds and surfaces as an immersive experience through virtual reality. With a Bluetooth controller and a simple head-mounted display such as Google cardboard, it turns into a powerful tool to investigate and explore 3D data.

A scientific paper describing this app has been published in the proceedings of the 11th International Conference on Computer Graphics, Visualization, Computer Vision and Image Processing (2017)

Features :

• Developed for virtual reality head mounted displays such has Google Cardboard

• All-native rendering utilizing OpenGL ES 2.0

• Supports point cloud ASCII files

• Colors the points from elevation, intensity or RGB values

• Supports point cloud with normals, rendered as surfel (work in progress)

• Supports point clouds up to few millions points (depends on the smartphone GPU)

• Supports surface mesh Wavefront .obj files

• Control camera movement with Blue-tooth controller or touchscreen

• * New * Demo files download-able from the start screen

• * New * Button mapping of blue-tooth controller detailed in the start screen menu

• * New * Casting mode to broadcast the 3D model on TV (requires a controller)

Note :

The currently supported input ASCII files are as follows, without header (The columns must be separated by space character : " ")

• 3 columns X Y Z :

1.234 2.567 3.891

• 4 columns X Y Z intensity (float) :

1.234 2.567 3.891 0.2

• 6 columns X Y Z R G B [0-255] :

1.234 2.567 3.891 125 250 135

• 6 columns X Y Z Nx Ny Nz (coordinates + normals):

1.234 2.567 3.891 0.11 0.07 0.91
