Struct RectRenderer

pub struct RectRenderer {
    pub buffer: InstanceBuffer<RectVertex>,
}

Instance Buffer Setup for Rect’s.

Fields

buffer: InstanceBuffer<RectVertex>

Instance Buffer holding all Rendering information for Rect’s.

Implementations

impl RectRenderer

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

Creates a new RectRenderer.

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 RectRenderer::finalize but after Rect::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 RectRenderer::add_buffer_store’s.

pub fn rect_update( &mut self, rect: &mut Rect, renderer: &mut GpuRenderer, atlas: &mut AtlasSet, buffer_layer: usize, )

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

Arguments

• rect: Rect we want to update and prepare for rendering.
• atlas: AtlasSet the Rect 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.
