Struct glium::texture::compressed_cubemap::CompressedCubemap
[−]
[src]
pub struct CompressedCubemap(_);
A compressed cube texture containing floating-point data.
Methods
impl CompressedCubemap[src]
fn sampled(&self) -> Sampler<CompressedCubemap>
Builds a Sampler marker object that allows you to indicate
how the texture should be sampled from inside a shader.
Example
let uniforms = uniform! { color_texture: texture.sampled().magnify_filter(glium::uniforms::MagnifySamplerFilter::Nearest) };
impl CompressedCubemap[src]
fn get_internal_format(&self) -> Result<InternalFormat, GetFormatError>
Determines the internal format of this texture.
The backend may not support querying the actual format, in which case an error is returned.
fn empty_with_format<F>(facade: &F, format: CompressedFormat, mipmaps: CompressedMipmapsOption, dimension: u32) -> Result<CompressedCubemap, TextureCreationError> where F: Facade
Creates an empty texture with a specific format.
The texture (and its mipmaps) will contain undefined data.
unsafe fn from_id<F: Facade>(facade: &F, format: CompressedFormat, id: GLuint, owned: bool, mipmap: MipmapsOption, ty: Dimensions) -> CompressedCubemap
Builds a new texture reference from an existing, externally created OpenGL texture.
If owned is true, this reference will take ownership of the texture and be responsible
for cleaning it up. Otherwise, the texture must be cleaned up externally, but only
after this reference's lifetime has ended.
fn width(&self) -> u32
Returns the width of that image.
fn height(&self) -> u32
Returns the height of that image.
fn dimensions(&self) -> u32
Returns the dimension of that image.
fn get_mipmap_levels(&self) -> u32
Returns the number of mipmap levels of the texture.
The minimum value is 1, since there is always a main texture.
fn read_compressed_data(&self) -> Option<(CompressedFormat, Vec<u8>)>
Reads the content of the texture to RAM without decompressing it before.
You should avoid doing this at all cost during performance-critical operations (for example, while you're drawing).
Returns the compressed format of the texture and the compressed data, gives
None when the internal compression format is generic or unknown.
fn resident(self) -> Result<ResidentTexture, BindlessTexturesNotSupportedError>
Turns the texture into a ResidentTexture.
This allows you to use the texture in a much more efficient way by storing a "reference to it" in a buffer (actually not a reference but a raw pointer).
See the documentation of ResidentTexture for more infos.
fn mipmap(&self, level: u32) -> Option<CompressedCubemapMipmap>
Access a single mipmap level of this texture.
fn main_level(&self) -> CompressedCubemapMipmap
Access the main mipmap level of this texture.
Methods from Deref<Target=TextureAny>
fn get_width(&self) -> u32
Returns the width of the texture.
fn get_height(&self) -> Option<u32>
Returns the height of the texture.
fn get_depth(&self) -> Option<u32>
Returns the depth of the texture.
fn kind(&self) -> TextureKind
Returns the kind of texture.
fn dimensions(&self) -> Dimensions
Returns the dimensions of the texture.
fn get_array_size(&self) -> Option<u32>
Returns the array size of the texture.
fn get_samples(&self) -> Option<u32>
Returns the number of samples of the texture if it is a multisampling texture.
fn first_layer(&self) -> TextureAnyLayer
Returns a structure that represents the first layer of the texture. All textures have a first layer.
fn layer(&self, layer: u32) -> Option<TextureAnyLayer>
Returns a structure that represents a specific layer of the texture.
Non-array textures have only one layer. The number of layers can be queried with
get_array_size.
Returns None if out of range.
fn get_texture_type(&self) -> Dimensions
Returns the type of the texture (1D, 2D, 3D, etc.).
fn get_internal_format(&self) -> Result<InternalFormat, GetFormatError>
Determines the internal format of this texture.
fn get_mipmap_levels(&self) -> u32
Returns the number of mipmap levels of the texture.
fn main_level(&self) -> TextureAnyMipmap
Returns a structure that represents the main mipmap level of the texture.
fn mipmap(&self, level: u32) -> Option<TextureAnyMipmap>
Returns a structure that represents a specific mipmap of the texture.
Returns None if out of range.
unsafe fn generate_mipmaps(&self)
Binds this texture and generates mipmaps.
