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 merge_workspace(&self) -> MergeWorkspace

Builds a new set of MergeWorkspace

These will be resized when first used (in submit_merge)

pub fn shade_workspace(&self) -> ShadeWorkspace

Builds a new set of ShadeWorkspace

These will be resized when first used (in either submit_color or submit_shade)

pub fn ssao_workspace(&self) -> SsaoWorkspace

Builds a new set of SsaoWorkspace

These will be resized when first used (in submit_ssao)

pub fn submit_merge( &self, image: &FlexBuffer<GeomBufferTag>, settings: MergeSettings, buf: &mut MergeWorkspace, ) -> Result<(), MergeError>

Accumulates an image into a merged image buffer

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 submit_shade( &self, image: &MergeWorkspace, ssao: Option<&SsaoWorkspace>, buf: &mut ShadeWorkspace, ) -> Result<(), ShadeError>

Submits an operation to shade an image

The output buffer is resized to fit the incoming image

pub fn submit_heightmap( &self, image: &MergeWorkspace, buf: &mut ShadeWorkspace, ) -> Result<(), HeightmapError>

Submits an operation to generate RGB color from a heightmap

The output buffer is resized to fit the incoming image

pub fn submit_ssao( &self, image: &MergeWorkspace, buf: &mut SsaoWorkspace, ) -> Result<(), SsaoError>

Submits a pass to compute an SSAO buffer

pub fn submit_color( &self, merge: &MergeWorkspace, world_to_model: &Matrix4<f32>, shape: &ShapeColorBuffers, bufs: &mut ColorWorkspace, out: &mut ShadeWorkspace, ) -> 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: &MergeWorkspace, world_to_model: &Matrix4<f32>, shape: &ShapeColorBuffers, bufs: &mut ColorWorkspace, vars: &ShapeVars<f32>, out: &mut ShadeWorkspace, ) -> 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
