Struct LightRenderer 

pub struct LightRenderer {
    pub buffer: InstanceBuffer<LightsVertex>,
    /* private fields */
}

Instance Buffer Setup for Lights.

Fields

buffer: InstanceBuffer<LightsVertex>

Instance Buffer holding all Rendering information for Lights.

Implementations

impl LightRenderer

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

Creates a new LightRenderer.

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 LightRenderer::finalize but after Lights::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 LightRenderer::add_buffer_store’s.

pub fn update( &mut self, lights: &mut Lights, renderer: &mut GpuRenderer, buffer_layer: usize, )

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

Arguments

• lights: Lights we want to update and prepare for rendering.
• buffer_layer: The Buffer Layer we want to add this Object too.

Trait Implementations

impl Debug for LightRenderer

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
