Struct rustic_zen::image::Image

pub struct Image { /* private fields */ }

Represents an image while ray rendering is happening

This struct uses floats to represent each pixel of the image so normalisation can happen after rendering finishes.

Image is created and populated by the renderer. Only export functions are exposed.

Implementations

impl Image

pub fn new(width: usize, height: usize) -> Self

Create new image with the given width and hieght;

Trait Implementations

impl ExportImage for Image

fn get_lightpower(&self) -> f32

Returns the lightpower of the scene most recently rendered to this image.

fn get_size(&self) -> (usize, usize)

Returns the image size in pixels in the format (width, height)

fn to_rgbaf32(&self) -> Vec<f32>

Outputs the image. Serialsiing the image to a sequence of 32 bit floating point RGBA samples stored in a Vec<f32>, suitible for use in high bit depth images such as used by blender.

fn to_rgba8(&self, rays: usize, exposure: f64, exponent: f32) -> Vec<u8>

Outputs the image. Serialsiing the image to a sequence of 8 bit RGB samples stored in a Vec<u8>, suitible for use in file streams and other outputs.

impl RenderImage for Image

fn draw_line(&self, ray: RayResult)

Called in every rendering thread to add a Ray to the render target

fn prepare_render(&mut self, lightpower: f32)

called momentarilly before the render begins to allow the render target to set it’s self up to receive calls to draw_line

fn finish_render(&mut self)

called immediately after a render ends to allow the render target to clean up or finalize results
