Struct SymbolVertex 

#[repr(C)]
pub struct SymbolVertex {
    pub position: [f32; 3],
    pub glyph_offset: [f32; 2],
    pub tex_coord: [f32; 2],
    pub color: [f32; 4],
    pub halo_color: [f32; 4],
    pub params: [f32; 4],
}

A vertex for the symbol GPU pipeline.

Renders SDF glyphs and icons as textured quads. Each glyph is a quad (4 vertices, 6 indices) that samples from an SDF glyph atlas texture. The fragment shader thresholds the SDF to produce crisp, scalable text with optional halo.

Fields

position: [f32; 3]

Glyph anchor position [x, y, z] in camera-relative meters.

glyph_offset: [f32; 2]

Glyph quad offset from anchor [dx, dy] in world-space meters.

tex_coord: [f32; 2]

Texture coordinates [u, v] into the SDF atlas.

color: [f32; 4]

Text colour [r, g, b, a].

halo_color: [f32; 4]

Halo colour [r, g, b, a].

params: [f32; 4]

Symbol parameters: [halo_width, gamma_scale, 0, 0].
