Muto::Renderer::SceneData

struct Muto::Renderer::SceneData

Scene data structure containing view-projection matrix.

Class Members
mat4	ViewProjectionMatrix	The combined view-projection matrix for the scene.

Member Function Documentation

BeginScene()

void Muto::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.

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

References s_SceneData.

EndScene()

void Muto::Renderer::EndScene ( )

static

Ends the current scene.

Note

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

    {
        MU_PROFILE_FUNCTION();
 
    }

GetAPI()

static RenderAPI::API Muto::Renderer::GetAPI ( )

inlinestatic

Retrieves the current rendering API.

{ return RenderAPI::GetAPI(); }

Init()

void Muto::Renderer::Init ( )

static

Initializes the renderer.

Note

This initializes both the RenderCommand and Renderer2D systems.

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

OnWindowResize()

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

static

Handles window resize events by resizing the viewport.

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

References Muto::RenderCommand::SetViewport().

Submit()

void Muto::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

    {
        MU_PROFILE_FUNCTION();
        shader->Bind();
        shader->SetMat4("u_ViewProjection", s_SceneData->ViewProjectionMatrix);
        shader->SetMat4("u_Transform", transform);
 
        vertexArray->Bind();
        RenderCommand::DrawIndexed(vertexArray);
    }

Member Data Documentation

s_SceneData

Renderer::SceneData * Muto::Renderer::s_SceneData = new Renderer::SceneData

Pointer to the current scene data.
