It shows a table of all the visuals that support OpenGL -and their capabilities. The format of the table is similar to glxinfo -on Unix systems: - - visual ~= pixel format descriptor - id = visual id (integer from 1 - max visuals) - dep = cColorBits - color depth - tp = dwFlags - visual type (wn: window, pb: pbuffer, bm: bitmap) - xsp = no analog - transparent pixel (currently always ".") - bfsz = cColorBits - framebuffer size - lvl = bReserved - overlay (>0), underlay (<0), main plane (0) - rgci = iPixelType - rb = rgba mode, ci = color index mode - db = dwFlags & PFD_DOUBLEBUFFER - double buffer flag (y = yes) - stro = dwFlags & PFD_STEREO - stereo flag (y = yes) - gene = dwFlags & PFD_GENERIC - software generic (y = yes) or ICD - geac = dwFlags & PFD_GENERIC_ACCELERATED - generic with hardware (MCD) - rsz = cRedBits - # bits of red - gsz = cGreenBits - # bits of green - bsz = cBlueBits - # bits of blue - asz = cAlphaBits - # bits of alpha - axbf = cAuxBuffers - # of aux buffers - dpth = cDepthBits - # bits of depth - stcl = cStencilBits - # bits of stencil - accum sz = cAccumBits - total # of bits in accumulation buffer - accum r = cAccumRedBits - # bits of red in accumulation buffer - accum g = cAccumGreenBits - # bits of green in accumulation buffer - accum b = cAccumBlueBits - # bits of blue in accumulation buffer - accum a = cAccumAlphaBits - # bits of alpha in accumulation buffer - ms ns/b = no analog - multisample buffers (currently always ".") - -In the 10th column, you will find two additional columns: - -ge ge -ne ac - -Those capture the PFD_GENERIC_FORMAT (gene) and -PFD_GENERIC_ACCELERATED (geac) flags of the Pixelformat descriptor. If -'gene' is set to no, there is most probably an ICD (Installable Client -Driver) at work, i.e., a full OpenGL implementation by a hardware -vendor. If 'gene' is set to yes and 'geac' to no, then the MS/SGI -(whichever is reported) software implementation is at work. If 'gene' -and 'geac' both are set to yes, then the generic implementation is -supplemented by hardware acceleration, which should most certainly -mean that an MCD (Mini Client Driver) is at work, i.e., a small driver -that only exposes the rasterization interface of the underlying -hardware. - -For additional details on what these flags mean, please refer to the -included source code. The original source code can be found in the -SGI OpenGL Windows SDK. - -For usage information, type 'wglinfo -h' - -The '-w' switch will case the program to list all pixelformats that -can be used for hardware accelerated rendering. Hence, all pixelformats -that can only render to bitmaps are omitted, making the output slightly more -readable. - -The '-d' switch works around problems with some implementations where it is -not possible to create an OpenGL context without special preparations (fullscreen -mode or others). It forces wglinfo to only print pixelformat information, but -no renderer information, which would require a context to be created. -This switch shouldn't be necessary for any current OpenGL driver. - -The '-v' switch lists the pixelformats in a verbose form. - -The '-s' sends the output to stdout instead of wglinfo.txt.
