Struct RenderContext 

pub struct RenderContext {
    pub model_stack: Vec<Model>,
    pub cache: Option<RcMut<RenderCache>>,
    pub progress_tx: Option<ProgressTx>,
    /* private fields */
}

The render context.

Keeps a stack of model nodes and the render cache.

Fields

model_stack: Vec<Model>

Model stack.

cache: Option<RcMut<RenderCache>>

Optional render cache.

progress_tx: Option<ProgressTx>

Progress is given as a percentage between 0.0 and 100.0.

Implementations

impl RenderContext

pub fn new( model: &Model, resolution: RenderResolution, cache: Option<RcMut<RenderCache>>, progress_tx: Option<ProgressTx>, ) -> RenderResult<Self>

Initialize context with current model and prerender model.

pub fn model(&self) -> Model

The current model (panics if it is none).

pub fn with_model<T>( &mut self, model: Model, f: impl FnOnce(&mut RenderContext) -> T, ) -> T

Run the closure f within the given model.

pub fn progress_in_percent(&self) -> f32

Return render progress in percent.

pub fn update_2d<T: Into<WithBounds2D<Geometry2D>>>( &mut self, f: impl FnOnce(&mut RenderContext, Model) -> RenderResult<T>, ) -> RenderResult<Geometry2DOutput>

Update a 2D geometry if it is not in cache.

pub fn update_3d<T: Into<WithBounds3D<Geometry3D>>>( &mut self, f: impl FnOnce(&mut RenderContext, Model) -> RenderResult<T>, ) -> RenderResult<Geometry3DOutput>

Update a 3D geometry if it is not in cache.

pub fn current_resolution(&self) -> RenderResolution

Return current render resolution.

Trait Implementations

impl Default for RenderContext

fn default() -> RenderContext

Returns the “default value” for a type.
