Detailed Description

Texture abstract base class.

Textures can either be used on their own as wrappers around GL textures or in conjunction with Renderer. If used with Renderer, bind() and unbind() will be called as needed when selected.

Note

See OpenGLES documentation of glTexParameter() for a discussion of filter and wrap modes.

Member Function Documentation

virtual void Texture::bind ( )

pure virtual

Binds this Texture to the current active texture stage.

The active texture stage is selected through Renderer::selectTexture(), or a call to glActiveTexture().

Implemented in DirectTexture.

virtual int Texture::getHeight ( ) const

pure virtual

Returns the height of this Texture in texels.

Implemented in DirectTexture.

virtual GLint Texture::getHorizontalWrapMode ( )

pure virtual

Returns the wrap mode to apply to the Texture horizontally.

Implemented in DirectTexture.

virtual GLint Texture::getMagnificationFilter ( )

pure virtual

Returns the magnification filter mode applied to this Texture.

Implemented in DirectTexture.

virtual GLint Texture::getMinificationFilter ( )

pure virtual

Returns the minification filter mode applied to this Texture.

Implemented in DirectTexture.

virtual GLint Texture::getVerticalWrapMode ( )

pure virtual

Returns the wrap mode to apply to the Texture vertically.

Implemented in DirectTexture.

virtual int Texture::getWidth ( ) const

pure virtual

Returns the width of this Texture in texels.

Implemented in DirectTexture.

virtual void Texture::setHorizontalWrapMode ( GLint  value )

pure virtual

Sets the wrap mode to apply to the Texture horizontally.

Parameters

value

Wrap mode

Implemented in DirectTexture.

virtual void Texture::setMagnificationFilter ( GLint  value )

pure virtual

Sets the magnification filter mode applied to this Texture.

Parameters

value

Filter mode to set

Implemented in DirectTexture.

virtual void Texture::setMinificationFilter ( GLint  value )

pure virtual

Sets the minification filter mode applied to this Texture.

Parameters

value

Filter mode to set

Implemented in DirectTexture.

virtual void Texture::setVerticalWrapMode ( GLint  value )

pure virtual

Sets the wrap mode to apply to the Texture vertically.

Parameters

value

Wrap mode

Implemented in DirectTexture.

virtual void Texture::unbind ( )

pure virtual

Unbinds this Texture from the current active texture stage.

Implemented in DirectTexture.
