QUESTION
i need to visualize around 50k-60k points in openGL i managed to print them all but when i use rotate it takes so much time between each rotation because it just prints all the data every single frame. is there a way to print all the data once and freeze the importing of the data so it will keep the image but stop processing?
...ANSWER
Answered 2019-Jun-28 at 20:12The bottleneck is the for loop and the glBegin
/glEnd
sequence. The data is read from the files in every frame.
Note, that drawing by using glBegin
/glEnd
sequences and the fixed function matrix stack is deprecated since decades.
Read the files once at start up and create a Vertex Buffer Object.
(Read more about Vertex Specification and Shader for a state-of-the-art way of rendering.)
The closest solution to your existing code is to use client side capability glEnableClientState
and fixed function attributes glVertexPointer
. With this solution you don't need any shader program.
In the following I assume that you use PyOpenGL.
Load the vertex coordinates to an array

Install pypcd
You can use pypcd like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
