Interface TSLLineJoinArgs

Build-time camera mode — the line graphs' config.isOrtho.

The RGBA32F line texture node (6 texels/segment).

Its width in texels — already .toVar()ed by the caller's prologue.

Viewport resolution uniform node.

Physical render-target pixels per CSS pixel.

Scene-relative near-cull distance (already floored).

This segment's own STORAGE slot, as an int node (self-reference guard).

Which end of the segment this call is for — a plain JS boolean, not a node: the caller evaluates BOTH ends unconditionally (see below), so the direction ternaries fold at graph-build time instead of emitting a select() that would materialise both arms per vertex.

False when near-clipping moved this endpoint off its source vertex.

texel4.y at the start vertex, texel4.z at the end one.

NDC of the shared vertex (ndcStart / ndcEnd).

This segment's unit direction in pixel space.

THIS END's clamped pixel half-width — segment-constant, NOT the calling vertex's. Both width-dependent decisions below (the 2 px gate and the axial-overshoot guard) feed a flat cap varying, so a per-vertex width would let the t=0 and t=1 corners of a tapered or foreshortened segment answer differently and hand the cap to the provoking vertex alone (WGSL provokes first, WebGL last — so the backends would disagree too).

View-space depth (-mvZ) of THIS segment's far endpoint, i.e. the one that is NOT the shared vertex, taken from the UNCLIPPED endpoint depths.

OUT — a vec2 .toVar() the caller pre-set to perpendicular * joinPixelWidth. Overwritten with the miter point only where the join actually applies, so every skipped path keeps the shipped expansion.

OUT — a float .toVar() the caller pre-set to -1.0 ("no partner reached, keep the code-implied cap"). Set to the screen-space suppression wherever a partner IS reached.
