PCD data needs to be converted in range which is understood by the OpenGL?

Greetings !!!

Context : We are working on the 3D modelling project where the lidar camera data is used to view 3D object on the Web Portal, the processing of the 3D model happens at the desktop CPP application. The Desktop CPP application is responsible for reconstruction of the models, optimization and decimation etc.

Problem Statement : We received a e57 file format data from the Lidar camera as an output. The CPP application takes the e57 as an input to extract the PCD data and images for scan. CPP application makes use of the OpenGL Lib to display the 3D models for processing and viewing purpose. When we trying to plot the PCD data on Open GL after parsing via e57 lib.

Can anyone help to understand what is the mistake in below code, also question does this PCD data needs to be converted in a ay which is understood by the Open GL lib. Looking forward for any response. Appreciate your time Thank you

Please see

In particular, Posting Guidelines #4 and #5. You’ve provided almost no info.

Also in case it matters to you, this code has chosen one of the slowest ways to draw pretty much anything in OpenGL. This is extreme legacy code and heavily discouraged if performance matters.

This code also suggests that you’re using a single-buffered context via the old GLUT library, which might have been valid in 1994. Today it’s just going to cause you huge trouble as you try to expand your program and port it to other hardware.

Thanks ! can you please suggest any reference and library so that it can be helpful in resolving issue.
