This extension is for creating a pixel buffer (p-buffer), also called offscreen buffer. It didn't suffer the problem of pixel ownership test, so if you want to do a screen capture with glReadPixels, covered part of your window by other windows is not a problem for a p-buffer.

Mar 17, 2019 · Hi All, I’m using the pBuffer (WGL_ARB_pbuffer) for rendering offscreen. I’m trying to get the stecil buffer for the pbuffer but i’m not getting allocated stencil buffer bits. i’m also setting the stencil buffer bits in the PIXELFORMATDESCRIPTOR but there i’m getting the valid pixel format. The attribute list is shown here int pf_attr[] = { WGL_SUPPORT_OPENGL_ARB, TRUE, // P-buffer ...

Description. glXCreatePbuffer creates an off-screen rendering area and returns its XID. Any GLX rendering context that was created with respect to config can be used to render into this window. Use glXMakeContextCurrent to associate the rendering area with a GLX rendering context.. The accepted attributes for a GLXPbuffer are:

Mar 17, 2019 · Of course you need to select a valid configuration first. And the attribute list for the config needs to contain EGL_SURFACE_TYPE, EGL_PBUFFER_BIT, otherwise you may get a config that doesn’t support pbuffers.

OpenGL Support Gazebo uses OpenGL to render images for both user feedback (ObserverCam model) and simulated cameras (e.g., MonoCam, StereoHead, SonyVID30 models).This document describes OpenGL concepts with which users should be familiar, and lists some limitations of particular OpenGL driver implementations.

The OpenGL extension WGL_ARB_pbuffer, used in conjunction with the WGL_ARB_pixel_format extension, offers the ability to render to an off-screen pixel buffer. On NVIDIA-based graphics cards, the off-screen buffer is stored in video memory and this process of rendering to an off-screen buffer is accelerated in hardware.

It's a little known fact, that you can use OpenGL render contexts not only on the drawable it has been created with first, but on any drawable with compatible settings. So if your PBuffer matches your main window's pixel format, you can detach the render context from the main window and attach it …

Jan 21, 2016 · Over the past few years, a new standard for managing OpenGL contexts has emerged: EGL. Initially driven by the requirements of the embedded space, the NVIDIA driver release 331 introduced EGL support, enabling context creation for OpenGL ES applications without the need for a running an X server.
