MitosisStages

MitosisStages shows one cell dividing into two, size pixels from its centre to its side. From delay it goes through the six stages of MitosisStage::ALL, each stage_time seconds long, and names each one above the cell (label):

• Interphase: the chromosomes lie loose and thin in the nucleus (seed places them).
• Prophase: they condense into X-shaped pairs of sister chromatids, the nuclear envelope breaks down and the centrosomes move to the poles.
• Metaphase: spindle fibres line them up across the middle.
• Anaphase: the sisters are pulled to opposite poles and the cell stretches.
• Telophase: a nucleus forms around each group and the chromosomes loosen.
• Cytokinesis: the cell pinches into two.

Chromosomes come in homologous pairs of one length, one of each pair coloured from each parent (colors). stage_at(seconds) says which stage shows at a time. Gallery scene: MitosisStages.

API

Components are plain structs. Set the fields you need and fill the rest with ..ui.defaults(): the defaults below come from the current theme (theme. values are fields of Theme).

MitosisStages

Field	Type	Default	Description
delay	f32	0.0	Seconds after the container’s start before interphase begins.
stage_time	f32	1.6	Seconds each stage lasts.
center	(f64, f64)	(0.0, -0.3)	The middle of the cell, in units of ui.space.
size	f32	300.0	Pixels from the cell’s centre to its side (half the width).
chromosomes	usize	4	Number of chromosomes in the cell; they come in homologous pairs of one length.
arm	f32	30.0	Pixels of the longest chromatid arm; the other pairs are shorter.
colors	Vec<Color>	vec![Color::hex("#ff8787"), Color::hex("#74c0fc")]	Colours of the chromosomes by parent, alternating along the list; empty uses the palette’s membrane colour.
seed	u64	3	Seed for where the chromosomes lie loose in interphase; the same seed gives the same layout.
palette	CellPalette	CellPalette::default()	Colours of the cytoplasm, membrane, nucleus and the other cell parts.
spindle_color	Color	Color::hex("#ced4da")	Colour of the spindle fibres, asters and centrosomes.
label	bool	true	Names the current stage above the cell when true.
label_style	TextStyle	theme.typography.body	The font of the stage name: family, size in pixels and weight.
label_color	Color	theme.colors.text	Colour of the stage name.
enter	Option<FadeIn>	None	Fade in at the start; None for none.
exit	Option<FadeOut>	None	Fade out before the end; None for none.

Methods:

• fn stage_at(&self, seconds: f32) -> MitosisStage: The stage shown seconds into the video.
