decodeRGB565()

static glm::dvec3 CesiumUtility::AttributeCompression::decodeRGB565 ( const uint16_t value )

inlinestatic

Decodes a RGB565-encoded color to a 3-component vector containing the normalized RGB values.

Parameters

value

The RGB565-encoded value.

Returns

The normalized RGB values.

octDecode()

static glm::dvec3 CesiumUtility::AttributeCompression::octDecode ( uint8_t x, uint8_t y )

inlinestatic

Decodes a unit-length vector in 2 byte 'oct' encoding to a normalized 3-component vector.

Parameters

x	The x component of the oct-encoded unit length vector.
y	The y component of the oct-encoded unit length vector.

Returns

The decoded and normalized vector.

octDecodeInRange()

template<typename T , class = typename std::enable_if<std::is_unsigned<T>::value>::type>

static glm::dvec3 CesiumUtility::AttributeCompression::octDecodeInRange ( T x, T y, T rangeMax )

inlinestatic

Decodes a unit-length vector in 'oct' encoding to a normalized 3-component vector.

Parameters

x	The x component of the oct-encoded unit length vector.
y	The y component of the oct-encoded unit length vector.
rangeMax	The maximum value of the SNORM range. The encoded vector is stored in log2(rangeMax+1) bits.

Returns

The decoded and normalized vector.
