Hello Triangle and Texture

Simple sample that features GL4, pure newt, glWindow options, animator, indexed drawing, dinamic attribute and frag data binding, interleaved data, vao, vbo (with normalization on one attribute), ibo (with shorts), uniform, glsl program (with specific suffix) and matrix jogl util, gl error check, key listener and right way to dispose.

There is also a gl3 version and a Texture sample.

All the samples are written in Java and Kotlin.

Common Mistakes

I suggest you to take a read to these two pages for a quick overview over the most common problems, it is a very useful reading, legacy sections are carefully signaled.

OpenGL GLSL

Another common mistake that may happen if you port code from C/C++ to Java is this one:

Caused by: com.jogamp.opengl.GLException: unpack pixel_buffer_object must be bound to call this method at jogamp.opengl.gl4.GL4bcImpl.checkBufferObject(GL4bcImpl.java:40621) at jogamp.opengl.gl4.GL4bcImpl.checkUnpackPBOBound(GL4bcImpl.java:40707) at jogamp.opengl.gl4.GL4bcImpl.glTexImage2D(GL4bcImpl.java:5535) at tests.gl320.Gl_320_fbo_blit.initTexture(Gl_320_fbo_blit.java:199)

This happens because in C/C++, when you just want to allocate the space for a texture using, for example, glTexImage2D, you should not pass 0 as the last argument, but null.

N.B: The use of color picking is NOT recommended on any hardware whose palette is partially emulated.

Java OpenGL Samples Pack

The Java OpenGL Samples Pack (called unsurprisingly jogl-samples) is a port of the OpenGL Samples Pack, a collection of OpenGL samples based on the OpenGL "core profile" specifications.

The project aims to promote the new OpenGL features making easier version transitions for OpenGL programmers with a complementary documentation for the OpenGL specification. Despite the fact that the OpenGL Samples Pack provides as simple (and dumb) as possible samples, it's not a tutorial for beginner but a project for programmers already familiar with OpenGL. The OpenGL Samples Pack is also a good OpenGL drivers feature test.

These samples illustrate mostly of the OpenGL features from ES 2.0 up to the last GL extenstions, same of them usually also called AZDO (Almost Zero Driver Overhead).
