as well as a table of visuals, aka. pixelformats. PBuffer and multiple output

wglinfo is a small utility that displays all available visuals,
|
||||
aka. pixelformats, in an OpenGL system along with renderer version
|
||||
information. 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.
