PBO-VBO Usage Hints Warnings

Hi All, I have an application,that renders to Texture using PBO like said here (http://www.songho.ca/opengl/gl_pbo.html) and some other drawings that are handled with VBO's.

When I run my application with '-Djogl.debug.DebugGL' argument, I had the following messages:

GLDebugEvent[ id 0x20071
	type Warning: generic
	severity Unknown (0x826b)
	source GL API
	msg Buffer detailed info: Buffer object 1 (bound to GL_VERTEX_ARRAY_BUFFER_BINDING_ARB, and GL_ARRAY_BUFFER_ARB, usage hint is GL_STATIC_DRAW) will use VIDEO memory as the source for buffer object operations.

I have NVIDIA Quadro FX 570 with the latest driver version. (With old driver version it doesn't print anything like above).

By the way, my app runs well.

Do you guys think that I'm doing something wrong? Have you ever got any of this messages ?

Please publish your JOGL application as a git tree.

I guess, I missrepresented my situation. It is not a commercial app, it's not even a proper project. I'm experiencing Java implementation's of Songho's tutorials. Which are published under http://www.songho.ca/opengl/gl_pbo.html.

Please publish your JOGL implementation of Songho's tutorials.
The link in your post only contain c++ examples.

Its impossible to test if we experience the same thing unless we can run the same code.

In my humble opinion, there is nothing wrong in the debug messages above but you should follow Xerxes' advise if you really want us to run your code on our machines to check whether there is something not working as expected.

Yup.

With general debug enabled, i.e. '-Djogl.debug.DebugGL',
the GL debug context is chosen and all messages are being dumped to stderr.
Those messages are of verbose nature (like the ones you have shown)
critical or even error cases.

For manual fine grained control of the GL debug context,
have a look at the unit test:

Thank you. So far, I understand that I may ignore that debug messages.

I run the code, that I shared above, with "-Djogl.debug.DebugGL".

You would need to check the spec of the PBO extension here, ofc,
to ensure compatibility ..
