java.lang.Objectjavax.media.nativewindow.Capabilities
javax.media.opengl.GLCapabilities
public class GLCapabilities
Specifies a set of OpenGL capabilities.
At creation time of a GLDrawable using GLDrawableFactory,
an instance of this class is passed,
describing the desired capabilities that a rendering context
must support, such as the OpenGL profile, color depth and whether stereo is enabled.
The actual capabilites of created GLDrawables are then reflected by their own
GLCapabilites instance, which can be queried with GLDrawable#getGLCapabilities().
It currently contains the minimal number of routines which allow
configuration on all supported window systems.

void |
setAccumAlphaBits(int accumAlphaBits)
Sets number of bits requested for accumulation buffer's alpha component. |
void |
setAccumBlueBits(int accumBlueBits)
Sets the number of bits requested for the accumulation buffer's blue component. |
void |
setAccumGreenBits(int accumGreenBits)
Sets the number of bits requested for the accumulation buffer's green component. |
void |
setAccumRedBits(int accumRedBits)
Sets the number of bits requested for the accumulation buffer's red component. |
void |
setDepthBits(int depthBits)
Sets the number of bits requested for the depth buffer. |
void |

void |
setNumSamples(int numSamples)
If sample buffers are enabled, indicates the number of buffers to be allocated. |
void |
setOnscreen(boolean onscreen)
Sets whether the drawable surface supports onscreen. If enabled this method also invokes setPBuffer(false)Defaults to true. |
void |
setPBuffer(boolean enable)
Enables or disables pbuffer usage. If enabled this method also invokes setOnscreen(false)Defaults to false. |
void |
setPbufferFloatingPointBuffers(boolean enable)
For pbuffers only, indicates whether floating-point buffers should be used if available. |
void |
setPbufferRenderToTexture(boolean enable)
