Function Documentation

◆ ClearScreen()

void TeaPacket::Graphics::ClearScreen ( const Color4 & color )

Clears the active Display with a color.

◆ DeInitialize()

void TeaPacket::Graphics::DeInitialize ( )

Deinitializes all Graphics related systems.

◆ FinishRenderTarget()

void TeaPacket::Graphics::FinishRenderTarget ( )

Concludes rendering to the current Interface::Display.

◆ Initialize()

bool TeaPacket::Graphics::Initialize ( )

Initializes any Graphics related systems.

◆ SetRenderTarget() [1/2]

void TeaPacket::Graphics::SetRenderTarget ( Display & display )

Sets the active viewport to the viewport contained within a display.

◆ SetRenderTarget() [2/2]

void TeaPacket::Graphics::SetRenderTarget ( Viewport & viewport )
