Hello,
I use lwjgl 2.9.3. My OpenGl version is 3.0 Mesa 17.0.3, on a linux computer.
And I can't create a geometry shader, contrary to other shaders.
glCreateShader(GL_GEOMETRY_SHADER) returns always 0.
Example:
Display.setDisplayMode(new DisplayMode(Settings.width,Settings.height));
Display.setTitle("3D");
Display.create(new PixelFormat().withSamples(Settings.antialiasing)); //Mutli-sampling.
System.out.println("OpenGL version: " + glGetString(GL_VERSION));
System.out.println("Geometry "+glCreateShader(GL_GEOMETRY_SHADER));
System.out.println("Fragment "+glCreateShader(GL_FRAGMENT_SHADER));Results :
QuoteOpenGL version: 3.0 Mesa 17.0.3
Geometry 0
Fragment 1
Could you help me ?
Thank you.
Please have a look at: https://www.khronos.org/opengl/wiki/Geometry_Shader
Geometry Shaders have been introduced in OpenGL 3.2.
Thank you ! Sorry for the silly question.
I just changed my version and it is working fine.
