Struct LightSrc

Source

pub struct LightSrc {
    pub pos: [f32; 3],
    pub r2: f32,
    pub sc: f32,
}

Expand description

One point light source for sprite (and, eventually, world) lighting. Mirror of voxlap’s lightsrc_t (voxlap5.h): position, squared reach radius, and intensity scale. The lighting math reads r2 not r, matching voxlap’s vx5.lightsrc[i].r2-keyed range check.

Fields§

§pos: [f32; 3]

World-space position.

§r2: f32

Squared influence radius. Voxels / sprites further than sqrt(r2) from pos get no contribution.

§sc: f32

Intensity scale — voxlap’s lightsrc_t::sc. Larger = brighter.
