Struct nannou::frame::ViewFramebufferObject

pub struct ViewFramebufferObject { /* fields omitted */ }

A helper type for managing a framebuffer associated with a window's view function.

Creating and maintaining the framebuffer that targets the Frames image can be a tedious task that requires a lot of boilerplate code. This type simplifies the process with a single update method that creates or recreates the framebuffer if any of the following conditions are met:

• The update method is called for the first time.
• The frame.image_is_new() method indicates that the swapchain or its images have recently been recreated and the framebuffer should be recreated accordingly.
• The given render pass is different to that which was used to create the existing framebuffer.

Methods

impl ViewFramebufferObject

pub fn update<R, F, A>(
    &mut self,
    frame: &Frame,
    render_pass: R,
    builder: F
) -> Result<(), FramebufferCreationError> where
    R: 'static + RenderPassAbstract + Send + Sync,
    F: FnOnce(FramebufferBuilder<R, ()>, Arc<AttachmentImage>) -> FramebufferBuilderResult<R, A>,
    A: 'static + AttachmentsList + Send + Sync, 

Ensure the framebuffer is up to date with the render pass and frame's image.
