Struct ImageRenderer

pub struct ImageRenderer {
    pub buffer: InstanceBuffer<ImageVertex>,
}

Instance Buffer Setup for Image.

Fields

buffer: InstanceBuffer<ImageVertex>

Implementations

impl ImageRenderer

pub fn new(renderer: &GpuRenderer) -> Result<Self, GraphicsError>

Creates a new ImageRenderer.

pub fn add_buffer_store( &mut self, renderer: &GpuRenderer, index: OrderedIndex, buffer_layer: usize, )

Adds a Buffer OrderedIndex to the Rendering Store to get processed. This must be done before ImageRenderer::finalize but after Image::update in order for it to Render.

Arguments

• index: The OrderedIndex of the Object we want to render.
• buffer_layer: The Buffer Layer we want to add this Object too.

pub fn finalize(&mut self, renderer: &mut GpuRenderer)

Finalizes the Buffer by processing staged OrderedIndex’s and uploading it to the GPU. Must be called after all the ImageRenderer::add_buffer_store’s.

pub fn image_update( &mut self, image: &mut Image, renderer: &mut GpuRenderer, atlas: &mut AtlasSet, buffer_layer: usize, )

Updates a Image and adds its OrderedIndex to staging using ImageRenderer::add_buffer_store. This must be done before ImageRenderer::finalize in order for it to Render.

Arguments

• image: Image we want to update and prepare for rendering.
• atlas: AtlasSet the Image needs to render with.
• buffer_layer: The Buffer Layer we want to add this Object too.

pub fn use_clipping(&mut self)

Sets the Instance Buffer to enable Rendering With Scissor Clipping. This must be Set for the Optional Bounds to be used.
