Struct tray_rust::film::render_target::RenderTarget

pub struct RenderTarget { /* fields omitted */ }

RenderTarget is a RGBF render target to write our image too while rendering

Methods

impl RenderTarget

pub fn new(
    image_dim: (usize, usize),
    lock_size: (usize, usize),
    filter: Box<dyn Filter + Send + Sync>
) -> RenderTarget

Create a render target with width * height pixels

pub fn write(&self, samples: &[ImageSample], region: &Region)

Write all the image samples to the render target

pub fn clear(&mut self)

Clear the render target to black

pub fn dimensions(&self) -> (usize, usize)

Get the dimensions of the render target

pub fn get_render(&self) -> Vec<u8>

Convert the floating point color buffer to 24bpp sRGB for output to an image

pub fn get_rendered_blocks(
    &self
) -> ((usize, usize), Vec<(usize, usize)>, Vec<f32>)

Get the blocks that have had pixels written too them. Returns the size of each block, a list of block positions in pixels and then pixels for the blocks (in a single f32 vec). The block's pixels are stored in the same order their position appears in the block positions vec and contain dim.0 * dim.1 * 4 f32's per block.

pub fn get_renderf32(&self) -> Vec<f32>

Get the raw floating point framebuffer
