Struct Renderer 

pub struct Renderer {
    pub textures: Textures<Texture>,
    /* private fields */
}

The main imgui-wgpu renderer.

Manages the wgpu render pipeline, GPU buffers, and texture storage needed to render imgui draw data. Create one with Renderer::new, then call Renderer::render (or Renderer::prepare + Renderer::split_render) each frame inside a wgpu render pass.

Fields

textures: Textures<Texture>

Texture storage for the font atlas and user-registered images.

Insert custom Textures here to get a TextureId for use with imgui image widgets. The font atlas texture is inserted automatically.

Implementations

impl Renderer

pub fn new( imgui: &mut Context, device: &Device, queue: &Queue, config: RendererConfig<'_>, ) -> Self

Create an entirely new imgui wgpu renderer.

pub fn prepare( &self, draw_data: &DrawData, render_data: Option<RenderData>, queue: &Queue, device: &Device, ) -> RenderData

Prepares buffers for the current imgui frame. This must be called before Renderer::split_render, and its output must be passed to the render call.

pub fn split_render<'r>( &'r self, draw_data: &DrawData, render_data: &'r RenderData, rpass: &mut RenderPass<'r>, ) -> RendererResult<()>

Render the current imgui frame. Renderer::prepare must be called first, and the output render data must be kept for the lifetime of the renderpass.

pub fn render<'r>( &'r mut self, draw_data: &DrawData, queue: &Queue, device: &Device, rpass: &mut RenderPass<'r>, ) -> RendererResult<()>

Render the current imgui frame.

pub fn reload_font_texture( &mut self, imgui: &mut Context, device: &Device, queue: &Queue, )

Updates the texture on the GPU corresponding to the current imgui font atlas.

This has to be called after loading a font.
