Constructor & Destructor Documentation

◆ Texture()

Ocean::Rendering::Texture::Texture ( )

protected

Creates a new texture object.

◆ ~Texture()

Ocean::Rendering::Texture::~Texture ( )

overrideprotected

Member Function Documentation

◆ adjustedToPowerOfTwo()

virtual bool Ocean::Rendering::Texture::adjustedToPowerOfTwo ( ) const

virtual

Returns whether the internal texture size has been extended to power-of-two dimensions to hand the reduced graphic power of the system.

Systems not providing the necessary graphic extensions to support non-power-of-two textures will use power-of-two textures automatically. Therefore, the texture transformation cannot be used on systems with reduced graphic power.

Returns: True, if so
