Enum GpuTransition 

pub enum GpuTransition {
    Fade,
    Dissolve,
    Wipe {
        angle: f32,
    },
    Dip {
        color: [f32; 3],
    },
}

The ff-render transition node an XfadeTransition renders as.

Carries the node’s static geometry only. progress and clip B are supplied per frame by the caller, so this stays comparable and cheap to hand around.

Variants

Fade

Linear cross-blend (ff_render::FadeTransitionNode).

Dissolve

Per-pixel threshold reveal (ff_render::DissolveTransitionNode).

Wipe

Directional wipe (ff_render::WipeTransitionNode), angle in radians.

The angle points at the edge clip B grows from, which is the opposite of the transition’s name: wiperight sweeps its edge rightward and so reveals B from the left (angle = PI). The model names a direction and ff_render wants an angle, so the conversion — and its inversion — happen here rather than being passed through raw (RK-020).

Fields

angle: f32

Wipe direction in radians.

Dip

Two-phase dip through a solid colour (ff_render::DipToColorNode).

color is RGB and normally within [0, 1], but the FFmpeg dips deliberately fall outside it — see this module’s DIP_BLACK. Nothing clamps it until the node’s final write, and rounding it back into range would put the middle of the dip up to 18.6 away from the export.

Fields

color: [f32; 3]

Dip colour, RGB; may sit outside [0, 1].
