How to configure V-REP 3.5 to use Lua 5.3 in Ubuntu 16.04 LTS PC

I am using V-REP 3.5 in Ubuntu 16.04 LTS PC. The default Lua comes with V-REP 3.5 is Lua 5.1. I want to know if it is possible to upgrade/install the Lua 5.3 in Ubuntu 16.04 and if so, how to configure V-REP to use this Lua.

Thanks

Painfully slow simulation while saving the colored point cloud to a file

I am using a Kinect sensor to get the depth and color images of the scene. Later, I am generating a colored point cloud. Finally, I am trying to save the colored point cloud to a file. Below is the code snippet- if (sim_call_type==sim_childscriptcall_sensing) then local file=io.open(fileIndex..'.csv...

Bitwise shift and logical operators in Lua script inside V-REP v3.4

This question isn't directly related to V-REP. I have little experience of programming in Lua. I am trying to convert the following statement from C to Lua language- int rgb = r << 16 | g << 8 | b; From the Google , I found that the following bit = require('bit') library can perform the bitwise oper...

Re: How to get the 3D point cloud of a scene from Kinect

Thanks, fferri for the wonderful help. I have following 5 questions. Please note that the aim is to get the colored point cloud from simulate Kinect v2. (1) In Kinect v2, the depth frame size is 512 x 424 pixels. In order to make it faster, I am assuming that the depth frame size is 256 x 212 (512/2...

Re: How to get the 3D point cloud of a scene from Kinect

I managed to implement the code based on the suggestions. I haven't tested it yet. However, it seems that this point cloud contains only (x, y, z) values but not the (r, g, b) values. Please see the code snippet below- if (sim_call_type==sim_childscriptcall_sensing) then measuredData={} if notFirstH...

Camera Parameters for Simulated Kinect v2 inside V-REP

I am using simulated Kinect inside V-REP. The provided model appears like Kinect v1.8 since the camera parameters are matching with 1.8. Well, I want to get the camera parameters for simulated Kinect v2 inside V-REP . More specifically, I need the following information- The x and y value for "Extrac...

Re: How to get the 3D point cloud of a scene from Kinect

So you want a simulated kinect? Yes, you are absolutely right. You can extract 3d coordinates from the depth map with vision filters Can you tell me how? How do I get the camera parameters to convert depth map into 3D? For example, in case of Kinect Microsoft SDK, we have CoordinateMapper which tak...
