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 set-gl-config in 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.
