## Detailed Documentation

Renderer used for rendering images in 3D space.

### Construction

    BillboardRenderer()

Creates a renderer with an empty image.

    BillboardRenderer(const std::string& texture_filename)

Creates a renderer with an image loaded from a file.

    BillboardRenderer(const glw::PTexture2D& texture)

Creates a renderer with an image stored in a provided texture.

### Methods

    void SetTexture(const glw::PTexture2D& texture)

Replaces currently set image with a new one.

    glw::PTexture2D GetTexture() const

Returns currently set texture.

    virtual bool IsCompatibileWithStyle(const hiro::draw::Style* style)

Test whether specified style is compatible with the object.

    virtual void OnRenderFaces()

Defines behavior on face rendering.
