Member Function Documentation

AddTag()

void Engine::GLRenderer::AddTag ( const std::string &  name, RenderTag  tag, ViewProjection  projection = ViewProjection::PROJECTION  )

overridevirtual

Adds a rendering step to the Flush cycle.

Parameters

name	key string of the rendering step
tag	shader vertex data
projection	the type of projection to use for the render step

Implements Engine::Renderer.

AddTexture()

float Engine::GLRenderer::AddTexture

(

const Ref< Texture > &

texture

)

Add a texture to the render sampler lookup.

Parameters

texture

texture reference

Returns

the index in the sampler lookup

Flush()

void Engine::GLRenderer::Flush ( )

overridevirtual

Draw the elements to the screen.

TODO: (assumes each draw is a quad) so for 4 verts / 4 * 6 is 6 calls this is to prevent overlapping draws

Implements Engine::Renderer.

SetClearColor()

void Engine::GLRenderer::SetClearColor ( uint32_t  c )

override

Set the color for the background whenever the color is cleared.

Submit()

void Engine::GLRenderer::Submit ( const std::string &  tag, const Ref< Transform > &  transform, const Ref< MeshRenderer > &  renderer  )

overridevirtual

Submit an object to the render queue right now it draw it right away

Parameters

mesh	to draw
transform	location to draw at

Implements Engine::Renderer.
