Immersive VR viewer for 3D point clouds and surface meshes
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
