RenderContext

Struct RenderContext 

Source
pub struct RenderContext {
    pub model_stack: Vec<Model>,
    pub cache: RenderCache,
}
Expand description

The render context.

Keeps a stack of model nodes and the render cache.

Fields§

§model_stack: Vec<Model>

Model stack.

§cache: RenderCache

Render cache.

Implementations§

Source§

impl RenderContext

Source

pub fn new() -> Self

Create default context.

Source

pub fn init(model: &Model, resolution: RenderResolution) -> RenderResult<Self>

Initialize context with current model and prerender model.

Source

pub fn model(&self) -> Model

The current model (panics if it is none).

Source

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

Run the closure f within the given model.

Source

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

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

TODO Add cache look up functionality.

Source

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

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

TODO Add cache look up functionality.

Source

pub fn current_resolution(&self) -> RenderResolution

Return current render resolution.
