NAME¶
glGetMultisamplefv - retrieve the location of a sampleC SPECIFICATION¶
void glGetMultisamplefv(GLenum pname, GLuint index, GLfloat *val);
PARAMETERS¶
pnameSpecifies the sample parameter name. pname must be
GL_SAMPLE_POSITION.
index
Specifies the index of the sample whose position to
query.
val
Specifies the address of an array to receive the position
of the sample.
DESCRIPTION¶
glGetMultisamplefv queries the location of a given sample. pname specifies the sample parameter to retrieve and must be GL_SAMPLE_POSITION. index corresponds to the sample for which the location should be returned. The sample location is returned as two floating-point values in val[0] and val[1], each between 0 and 1, corresponding to the x and y locations respectively in the GL pixel space of that sample. (0.5, 0.5) this corresponds to the pixel center. index must be between zero and the value of GL_SAMPLES minus one.If the multisample mode does not have fixed sample locations, the returned values may only reflect the locations of samples within some pixels.
ERRORS¶
GL_INVALID_ENUM is generated if pname is not one GL_SAMPLE_POSITION.GL_INVALID_VALUE is generated if index is greater than or equal to the value of GL_SAMPLES.
