Texture state class which encapsulates OpenGl texture functionality

Texture()

static Texture* instance()

virtual Object* clone() const

virtual bool isSameKindAs(Object* obj)

virtual const char* className() const

void setImage(Image* image)

Set the texture image.

Image* getImage() const

Get the texture image.

enum WrapParameter WRAP_S WRAP_T WRAP_R

enum WrapMode CLAMP REPEAT

void setWrap(WrapParameter which, WrapMode wrap)

Set the texture wrap mode

WrapMode getWrap(WrapParameter which) const

Get the texture wrap mode

enum FilterParameter MIN_FILTER MAG_FILTER

enum FilterMode LINEAR LINEAR_MIPMAP_LINEAR LINEAR_MIPMAP_NEAREST NEAREST NEAREST_MIPMAP_LINEAR NEAREST_MIPMAP_NEAREST ANISOTROPIC

void setFilter(FilterParameter which, FilterMode filter)

Set the texture filter mode

FilterMode getFilter(FilterParameter which) const

Get the texture filter mode

enum InternalFormatMode USE_IMAGE_DATA_FORMAT USE_USER_DEFINED_FORMAT USE_ARB_COMPRESSION USE_S3TC_DXT1_COMPRESSION USE_S3TC_DXT3_COMPRESSION USE_S3TC_DXT5_COMPRESSION

void setInternalFormatMode(InternalFormatMode mode)

Set the internal format mode. Note, If the mode is set USE_IMAGE_DATA_FORMAT, USE_ARB_COMPRESSION, USE_S3TC_COMPRESSION the internalFormat is automatically selected, and will overwrite the previous _internalFormatValue.
