チャンネルの名称
- RGBA
- D=デプス
- S=ステンシル
数字=ビット数
- 8bit=2の8乗=256階調
- 16bit=2の16乗=65536階調
数値の名称
- SNorm=signed normalized=[-1,1]の範囲
- UNorm: unsigned normalized=[0,1]
- UInt: The components are unsigned integer values in the range [0, 2n-1]
- SInt: The components are signed integer values in the range [-2n-1,2n-1-1].
- UFloat: The components are unsigned floating-point numbers (used by packed, shared exponent, and some compressed formats).
- SFloat: The components are signed floating-point numbers.
sRGB nonlinear encoding
- SRGB: The R, G, and B components are unsigned normalized values that represent values using sRGB nonlinear encoding, while the A component (if one exists) is a regular unsigned normalized value.
- PACKnn: The format is packed into an underlying type with nn bits.
容量
- チャンネル数xビット数できまる
- signed/unsignedなどは関係ない
説明
- ARGB32 = 8bit x 4channel = 32
- ARGBHalf = それぞれ16bitの不動小数点、floatの半分?
- ARGBFloat = それぞれ32bit
