Member Function Documentation

◆ flipBuffer()

virtual void Freescape::Renderer::flipBuffer ( )
inlinevirtual

Swap the buffers, making the drawn screen visible

Reimplemented in Freescape::OpenGLShaderRenderer, and Freescape::TinyGLRenderer.

◆ positionCamera()

virtual void Freescape::Renderer::positionCamera ( const Math::Vector3d &  pos,
const Math::Vector3d &  interest,
float  rollAngle = 0.0f 
)
pure virtual

Select the window where to render

This also sets the viewport

Implemented in Freescape::OpenGLShaderRenderer, and Freescape::TinyGLRenderer.
