Enum sierra::BlendFactor [−][src]
Defines how blend factor is calculated.
For each variant comment contains an equivalent Rust expression
where Rs
, Gs
, Bs
and As
are value components from fragment shader’s
color output, Rd
, Gd
, Bd
and Ad
are value components stored in
attachment, and Rc
, Gc
, Bc
and Ac
are value components defined in
constants
.
