Hello Triangle

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.

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.
