Class INTELConservativeRasterization

public final class INTELConservativeRasterization extends java.lang.Object
Native bindings to the INTEL_conservative_rasterization extension.Regular rasterization includes fragments with at least one sample covered by a polygon. Conservative rasterization includes all fragments that are at least partially covered by the polygon.
In some use cases, it is also important to know if a fragment is fully covered by a polygon, i.e. if all parts of the fragment are within the polygon. An application may, for example, want to process fully covered fragments different from the "edge" pixels. This extension adds an option for the fragment shader to receive this information via
gl_SampleMaskIn[]
.This extension affects only polygons in
FILL
mode and specifically does not imply any changes in processing of lines or points.Conservative rasterization automatically disables polygon antialiasing rasterization if enabled by
POLYGON_SMOOTH
.Requires
OpenGL 4.2
