Implementations

impl HeadlessRenderer

pub fn new(width: u32, height: u32) -> Self

pub fn with_backend( width: u32, height: u32, backend: Box<dyn BackendContext>, ) -> Self

pub fn render_to_buffer( &mut self, scene: &SceneDesc, camera: &CameraDesc, ) -> Vec<u8>

Render a scene to an RGBA pixel buffer.

pub fn render_to_png( &mut self, scene: &SceneDesc, camera: &CameraDesc, path: &str, )

Render to an image file. Despite the name, the extension picks the format (.png, .tga, .bmp, .jpg, .gif). Write errors are logged; use try_render_to_file to get them back.

pub fn try_render_to_file( &mut self, scene: &SceneDesc, camera: &CameraDesc, path: &str, ) -> Result<()>

Render to an image file, returning any encoding or write error.

pub fn resize(&mut self, width: u32, height: u32)

Resize the render targets.

pub fn renderer(&self) -> &MultiBackendRenderer

Access the inner renderer.

pub fn renderer_mut(&mut self) -> &mut MultiBackendRenderer
