Struct Context 

pub struct Context { /* private fields */ }

WGPU context for applying various effects

Implementations

impl Context

pub fn new(gpu: &Gpu) -> Self

Builds a new context for applying effects

pub fn submit_merge( &self, image: &FlexBuffer<PixelBufferTag>, remove_nans: bool, buf: &mut MergeWorkspace, ) -> Result<(), MergeError>

Submits a set of merge operations to accumulate a single image

MergeWorkspace::reset should be called before the first call to submit_merge. For the first merge after a reset, the output buffer is resized to fit the images; subsequent merges must be of the same size.

pub fn merge_workspace(&self) -> MergeWorkspace

Builds a new set of MergeWorkspace for the given image size

pub fn submit_color( &self, merge: &mut MergeWorkspace, settings: ColorSettings, shape: &ShapeColorBuffers, bufs: &mut ColorWorkspace, ) -> Result<(), ColorError>

Submits a color evaluation pass

Image size is set from the MergeWorkspace; the transform matrix is provided separately (but should be the same one used for image evaluation).

pub fn submit_color_with_vars( &self, merge: &mut MergeWorkspace, settings: ColorSettings, shape: &ShapeColorBuffers, bufs: &mut ColorWorkspace, vars: &ShapeVars<f32>, ) -> Result<(), ColorError>

Submits a color evaluation pass with auxiliary variables

Image size is set from the MergeWorkspace; the transform matrix is provided separately (but should be the same one used for image evaluation).

pub fn color_workspace(&self) -> ColorWorkspace

Returns a new workspace for color evaluation
