pub struct Renderer { /* private fields */ }

Implementations

impl Renderer

pub fn init( ctx: &mut Context, device: Arc<Device>, queue: Arc<Queue>, format: Format, ) -> Result<Renderer, Box<dyn Error>>

Initialize the renderer object, including vertex buffers, ImGui font textures, and the Vulkan graphics pipeline.

---

ctx: the ImGui Context object

device: the Vulkano Device object for the device you want to render the UI on.

queue: the Vulkano Queue object for the queue the font atlas texture will be created on.

format: the Vulkano Format that the render pass will use when storing the frame in the target image.

pub fn draw_commands<I>( &mut self, cmd_buf_builder: &mut AutoCommandBufferBuilder<PrimaryAutoCommandBuffer>, _queue: Arc<Queue>, target: I, draw_data: &DrawData, ) -> Result<(), Box<dyn Error>>

where I: ImageViewAbstract + Send + Sync + 'static,

Appends the draw commands for the UI frame to an AutoCommandBufferBuilder.

---

cmd_buf_builder: An AutoCommandBufferBuilder from vulkano to add commands to

device: the Vulkano Device object for the device you want to render the UI on

queue: the Vulkano Queue object for buffer creation

target: the target image to render to

draw_data: the ImGui DrawData that each UI frame creates

pub fn reload_font_texture( &mut self, ctx: &mut Context, device: Arc<Device>, queue: Arc<Queue>, ) -> Result<(), Box<dyn Error>>

Update the ImGui font atlas texture.

---

ctx: the ImGui Context object

device: the Vulkano Device object for the device you want to render the UI on.

queue: the Vulkano Queue object for the queue the font atlas texture will be created on.

pub fn textures(&mut self) -> &mut Textures<Texture>

Get the texture library that the renderer uses
