template<GLenum TEXTURE_TYPE>
class cy::GLTexture< TEXTURE_TYPE >
OpenGL texture base class.
This class provides a convenient interface for handling basic texture operations with OpenGL. The template argument TEXTURE_TYPE should be a texture type supported by OpenGL, such as GL_TEXTURE_1D, GL_TEXTURE_2D, GL_TEXTURE_3D, GL_TEXTURE_CUBE_MAP, GL_TEXTURE_RECTANGLE, GL_TEXTURE_1D_ARRAY, GL_TEXTURE_2D_ARRAY, GL_TEXTURE_CUBE_MAP_ARRAY, GL_TEXTURE_BUFFER, GL_TEXTURE_2D_MULTISAMPLE, or GL_TEXTURE_2D_MULTISAMPLE_ARRAY. This class merely stores the texture id. Note that deleting an object of this class does not automatically delete the texture from the GPU memory. You must explicitly call the Delete() method to free the texture storage on the GPU.

|
| GLTexture () |
| | Constructor.
|
| |
|
|
void | Delete () |
| | Deletes the texture.
|
| |
|
GLuint | GetID () const |
| | Returns the texture ID.
|
| |
|
bool | IsNull () const |
| | Returns true if the OpenGL texture object is not generated, i.e. the texture id is invalid.
|
| |
|
void | Bind () const |
| | Binds the texture to the current texture unit.
|
| |
|
void | Bind (int textureUnit) const |
| | Binds the texture to the given texture unit.
|
| |
|
GLenum | Type () const |
| | Deletes the texture.
|
| |
|
|
void | Initialize () |
| | Generates the texture, only if the texture has not been previously generated. Initializes the texture sampling parameters.
|
| |
|
void | BuildMipmaps () |
| | Builds mipmap levels for the texture. The texture image must be set first.
|
| |
|
void | SetFilteringMode (GLenum magnificationFilter, GLenum minificationFilter) |
| | Sets the texture filtering mode. The acceptable values are GL_NEAREST and GL_LINEAR. The minification filter values can also be GL_NEAREST_MIPMAP_NEAREST, GL_LINEAR_MIPMAP_NEAREST, GL_NEAREST_MIPMAP_LINEAR, or GL_LINEAR_MIPMAP_LINEAR. If the filter argument is zero, the corresponding filter parameter is not changed.
|
| |
|
void | SetAnisotropy (float anisotropy) |
| | Sets the anisotropy level of the texture. The anisotropy value of 1 disables anisotropic filtering. Larger values provide provide better anisotropic filtering.
|
| |
|
void | SetMaxAnisotropy () |
| | Sets anisotropic filtering to the maximum permissible value.
|
| |
|
void | SetNoAnisotropy () |
| | Turns off anisotropic filtering.
