Class NVFramebufferMixedSamples

java.lang.Object
org.lwjgl.opengl.NVFramebufferMixedSamples
public class NVFramebufferMixedSamples extends Object
Native bindings to the NV_framebuffer_mixed_samples extension.

This extension allows multisample rendering with a raster and depth/stencil sample count that is larger than the color sample count. Rasterization and the results of the depth and stencil tests together determine the portion of a pixel that is "covered". It can be useful to evaluate coverage at a higher frequency than color samples are stored. This coverage is then "reduced" to a collection of covered color samples, each having an opacity value corresponding to the fraction of the color sample covered. The opacity can optionally be blended into individual color samples.

    • glRasterSamplesEXT

      public static void glRasterSamplesEXT(int samples, boolean fixedsamplelocations)
      Selects the number of samples to be used for rasterization. samples represents a request for a desired minimum number of samples. Since different implementations may support different sample counts, the actual sample pattern used is implementation-dependent. However, the resulting value for RASTER_SAMPLES_EXT is guaranteed to be greater than or equal to samples and no more than the next larger sample count supported by the implementation. If fixedsamplelocations is TRUE, identical sample locations will be used for all pixels. The sample locations chosen are a function of only the parameters to RasterSamplesEXT and not of any other state.

      If RASTER_MULTISAMPLE_EXT is enabled, then the sample pattern chosen by RasterSamplesEXT will be used instead of sampling at the center of the pixel. The sample locations can be queried with GetMultisamplefv with a pname of SAMPLE_POSITION, similar to normal multisample sample locations.

      The value MULTISAMPLE_RASTERIZATION_ALLOWED_EXT is TRUE if SAMPLE_BUFFERS is one or if RASTER_MULTISAMPLE_EXT is enabled. The value EFFECTIVE_RASTER_SAMPLES_EXT is equal to RASTER_SAMPLES_EXT if RASTER_MULTISAMPLE_EXT is enabled, otherwise is equal to SAMPLES.

      Explicit multisample rasterization can not be used in conjunction with depth, stencil, or depth bounds tests, multisample framebuffers, or if RASTER_SAMPLES_EXT is zero. If RASTER_MULTISAMPLE_EXT is enabled, the error INVALID_OPERATION will be generated by Draw commands if

      Errors

      An INVALID_VALUE error is generated if samples is greater than the value of MAX_RASTER_SAMPLES_EXT (the implementation-dependent maximum number of samples).

      Parameters:
      samples - the number of samples to be used for rasterization
      fixedsamplelocations - if TRUE, identical sample locations will be used for all pixels
