Member Function Documentation

BeginScene()

void Vesper::Renderer::BeginScene ( OrthographicCamera & camera )

static

Begins a new scene with the given orthographic camera.

Parameters

camera

The orthographic camera defining the view and projection for the scene.

Todo

Support for other camera types.

    {
        VZ_PROFILE_FUNCTION();
        s_SceneData->ViewProjectionMatrix = camera.GetViewProjectionMatrix();
    }

References s_SceneData.

EndScene()

void Vesper::Renderer::EndScene ( )

static

Ends the current scene.

Note

Currently does nothing as scene closure is automatic, but could be useful for a render interface

    {
        VZ_PROFILE_FUNCTION();
 
    }

GetAPI()

RendererAPI::API Vesper::Renderer::GetAPI ( )

inlinestatic

Retrieves the current rendering API.

{ return RendererAPI::GetAPI(); }

Init()

void Vesper::Renderer::Init ( )

static

Initializes the renderer.

Note

This initializes both the RenderCommand and Renderer2D systems.

    {
        VZ_PROFILE_FUNCTION();
 
        RenderCommand::Init();
        Renderer2D::Init();
    }

OnWindowResize()

void Vesper::Renderer::OnWindowResize ( uint32_t width, uint32_t height )

static

Handles window resize events by resizing the viewport.

    {
        VZ_PROFILE_FUNCTION();
        RenderCommand::SetViewport(0, 0, width, height);
    }

References Vesper::RenderCommand::SetViewport().

Submit()

void Vesper::Renderer::Submit ( const Ref< Shader > & shader, const Ref< VertexArray > & vertexArray, const glm::mat4 & transform = glm::mat4(1.0f) )

static

Submits a draw call with the specified shader, vertex array, and transform.

Parameters

shader	The shader to use for rendering.
vertexArray	The vertex array to draw.
transform	The transformation matrix to apply.

Todo

Set up a command list to encapsulate this for draw order control

    {
        VZ_PROFILE_FUNCTION();
        shader->Bind();
        std::dynamic_pointer_cast<OpenGLShader>(shader)->UploadUniformMat4("u_ViewProjection", s_SceneData->ViewProjectionMatrix);
        std::dynamic_pointer_cast<OpenGLShader>(shader)->UploadUniformMat4("u_Transform", transform);
 
        vertexArray->Bind();
        RenderCommand::DrawIndexed(vertexArray);
    }
