Package org.lwjgl.opengl

Class NVExplicitMultisample

java.lang.Object

org.lwjgl.opengl.NVExplicitMultisample

public class NVExplicitMultisample
extends java.lang.Object

Native bindings to the NV_explicit_multisample extension.

In traditional multisample specs, the API only allows access to the samples indirectly through methods such as coverage values and downsampled readbacks. NV_explicit_multisample adds a set of new capabilities to allow more precise control over the use of multisamples. Specifically, it adds:

• A query in the API to query the location of samples within the pixel
• An explicit control for the multisample sample mask to augment the control provided by SampleCoverage
• A new texture target to wrap a renderbuffer and allow a restricted class of accesses to the samples
• The ability to fetch a specific sample from a multisampled texture from within a shader
• A program option to enable the new behavior

Requires OpenGL 2.0 and ARB_multisample.
