Struct Mtl 

Source 
pub struct Mtl {
    pub filename: String,
    pub materials: Vec<Arc<Material>>,
}
Expand description

The data represented by the mtllib command.

The material name is replaced by the actual material data when the material libraries are laoded if a match is found.

Fields§

§filename: String

Name of the .mtl file.

§materials: Vec<Arc<Material>>

A list of loaded materials.

The individual materials are wrapped into an Arc to facilitate referencing this data where these materials are assigned in the .obj file.

Implementations§

Source§

impl Mtl

Source

pub fn new(filename: String) -> Self

Construct a new empty mtl lib with the given file name.

Source

pub fn reload_with<R, F>( &mut self, obj_dir: impl AsRef<Path>, resolve: F, ) -> Result<&mut Self, MtlError>
where R: BufRead, F: FnMut(&Path, &str) -> Result<R>,

Load the mtl library from the input buffer generated by the given closure.

This function overwrites the contents of this library if it has already been loaded.

Source

pub fn reload(&mut self, input: impl Read) -> Result<&mut Self, MtlError>

Load the mtl library from the given input buffer.

This function overwrites the contents of this library if it has already been loaded.

Source

pub fn write_to_buf(&self, out: &mut impl Write) -> Result<(), Error>
