Struct PassView 

pub struct PassView<'r> { /* private fields */ }

Read-only paint view returned by ViewportRenderer::pass_view.

Identical to PassPath but constructed from a shared reference, making it usable in framework paint callbacks where only & access to the renderer is available (e.g. eframe’s CallbackTrait::paint).

Implementations

impl<'r> PassView<'r>

pub fn paint<'rp>(&self, render_pass: &mut RenderPass<'rp>, frame: &FrameData)

Single viewport: issue draw calls into render_pass.

pub fn paint_viewport<'rp>( &self, render_pass: &mut RenderPass<'rp>, id: ViewportId, frame: &FrameData, )

Multi-viewport: issue draw calls for id into render_pass.

pub fn paint_hdr_blit<'rp>( &self, render_pass: &mut RenderPass<'rp>, frame: &FrameData, )

Multi-viewport HDR: blit the intermediate texture for frame’s viewport into render_pass.

Call after PassPath::prepare_hdr_viewport for the same viewport. Set the render pass viewport and scissor rect to the correct region before calling.

The render pass must have a Depth24PlusStencil8 depth-stencil attachment (as eframe callbacks always do). For render passes without a depth attachment (e.g. a plain winit blit pass), use paint_hdr_blit_no_ds instead.

pub fn paint_hdr_blit_no_ds<'rp>( &self, render_pass: &mut RenderPass<'rp>, frame: &FrameData, )

Like [paint_hdr_blit] but for render passes without a depth-stencil attachment.

Use this when you create the blit render pass yourself (e.g. winit) and the pass has no depth attachment. The resulting blit is identical; only the pipeline variant differs to match the render pass format.
