Recently I’ve been working on a rendering engine in LWJGL and I’ve come across numerous issues with versions. So I am after advice on what would be the correct versions to use with this new project.
Firstly, LWJGL 2 or LWJGL 3? Version 2 is still current but version 3 is a complete rewrite and is still missing some utility classes; such as GLU.gluPerspective(…);
After using LWJGL 2 for the compatibility, I have then come across more issues;
As I want to stick with modern OpenGL, I am using VBOs to render my faces. However when using GLSL to do some basic lighting, I have had to use GLSL 140 to ensure compatibility with the functions like normalise() and transform(). Then i had to enable GL_ARB_compatibility to let me access gl_Normal, gl_Vertex and gl_Color, Like so:
#version 140
#extension GL_ARB_compatibility : require
Basically all I’m asking is for some current advice, all the tutorials on the internet are different and outdated.
So, to my questions:
- What LWJGL version would you recommend? is 3 complete enough to use in production?
- What GLSL version should I use?
- What are the replacements for the data I am using the compatibility layer to access?
- Are there any nice up to date resources or tutorials for Modern OpenGL?
Thanks in advance for clarifying this for me. It’s a steep learning curve
