| gl-config% : class? |
superclass: object% |
A gl-config% object encapsulates configuration information
for an OpenGL drawing context. Use a gl-config% object as an
initialization argument for canvas% or provide it to
make-gl-bitmap.
(new gl-config%) → (is-a?/c gl-config%)
Creates a GL configuration that indicates double buffering, a depth
buffer of size one, no stencil buffer, no accumulation buffer, no
multisampling, and not stereo.
(send a-gl-config get-accum-size) → (integer-in 0 256)
Reports the accumulation-buffer size (for each of red, green, blue,
and alpha) that the configuration requests, where zero means no
accumulation buffer is requested.
(send a-gl-config get-depth-size) → (integer-in 0 256)
Reports the depth-buffer size that the configuration requests, where
zero means no depth buffer is requested.
(send a-gl-config get-double-buffered) → boolean?
Reports whether the configuration requests double buffering or not.
(send a-gl-config get-multisample-size) → (integer-in 0 256)
Reports the multisampling size that the configuration requests, where
zero means no multisampling is requested.
(send a-gl-config get-stencil-size) → (integer-in 0 256)
Reports the stencil-buffer size that the configuration requests, where
zero means no stencil buffer is requested.
(send a-gl-config get-stereo) → boolean?
Reports whether the configuration requests stereo or not.
(send a-gl-config set-accum-size on?) → void? on? : (integer-in 0 256)
Adjusts the configuration to request a particular accumulation-buffer
size for every channel (red, green, blue, and alpha), where zero
means no accumulation buffer is requested.
(send a-gl-config set-depth-size on?) → void? on? : (integer-in 0 256)
Adjusts the configuration to request a particular depth-buffer size,
where zero means no depth buffer is requested.
(send a-gl-config set-double-buffered on?) → void? on? : any/c
Adjusts the configuration to request double buffering or not.
(send a-gl-config set-multisample-size on?) → void? on? : (integer-in 0 256)
Adjusts the configuration to request a particular multisample size,
where zero means no multisampling is requested. If a multisampling
context is not available, this request will be ignored.
(send a-gl-config set-stencil-size on?) → void? on? : (integer-in 0 256)
Adjusts the configuration to request a particular stencil-buffer size,
where zero means no stencil buffer is requested.
(send a-gl-config set-stereo on?) → void? on? : any/c
Adjusts the configuration to request stereo or not.
