◆ isSignedIntNormalizationSymmetric()

static bool inviwo::OpenGLCapabilities::isSignedIntNormalizationSymmetric ( )
static

The conversion from normalized fixed-point integers to floating-point values and back was changed to use a symmetric range in OpenGL 4.2. That is the range [-127, 127] is used for the normalization of 8bit signed integers instead of [-128, 127].
