Struct gltf::material::Volume

pub struct Volume<'a> { /* private fields */ }

This is supported on crate feature KHR_materials_volume only.

Parameter values that define a volume for the transmission of light through the material

Implementations

impl<'a> Volume<'a>

pub fn thickness_factor(&self) -> f32

The thickness of the volume beneath the surface. The value is given in the coordinate space of the mesh. If the value is 0 the material is thin-walled. Otherwise the material is a volume boundary. The doubleSided property has no effect on volume boundaries. Range is [0, +inf).

pub fn thickness_texture(&self) -> Option<Info<'a>>

A texture that defines the thickness, stored in the G channel. This will be multiplied by thickness_factor. Range is [0, 1].

pub fn attenuation_distance(&self) -> f32

Density of the medium given as the average distance that light travels in the medium before interacting with a particle. The value is given in world space. Range is (0, +inf).

pub fn attenuation_color(&self) -> [f32; 3]

The color that white light turns into due to absorption when reaching the attenuation distance.

pub fn extras(&self) -> &'a Extras

Optional application specific data.
