Struct glium::texture::texture2d_multisample::Texture2dMultisample
[−]
[src]
pub struct Texture2dMultisample(_);
A two-dimensional texture containing floating-point data.
Methods
impl Texture2dMultisample
fn sampled(&self) -> Sampler<Texture2dMultisample>
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 Texture2dMultisample
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<F>(facade: &F, width: u32, height: u32, samples: u32) -> Result<Texture2dMultisample, TextureCreationError> where F: Facade
Creates an empty texture.
No mipmap level (except for the main level) will be allocated or generated.
The texture will contain undefined data.
fn empty_with_format<F>(facade: &F, format: UncompressedFloatFormat, mipmaps: MipmapsOption, width: u32, height: u32, samples: u32) -> Result<Texture2dMultisample, TextureCreationError> where F: Facade
Creates an empty texture with a specific format.
The texture (and its mipmaps) will contain undefined data.
fn empty_with_mipmaps<F>(facade: &F, mipmaps: MipmapsOption, width: u32, height: u32, samples: u32) -> Result<Texture2dMultisample, TextureCreationError> where F: Facade
Creates an empty texture. Specifies whether is has mipmaps.
The texture (and its mipmaps) will contain undefined data.
fn as_surface<'a>(&'a self) -> SimpleFrameBuffer<'a>
Starts drawing on the texture.
All the function calls to the framebuffer will draw on the texture instead of the screen.
Low-level information
The first time that this function is called, a FrameBuffer Object will be
created and cached. The following calls to as_surface will load the existing
FBO and re-use it. When the texture is destroyed, the FBO is destroyed too.
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 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 first_layer(&self) -> Texture2dMultisampleLayer
Access the first layer of this texture.
fn layer(&self, layer: u32) -> Option<Texture2dMultisampleLayer>
Access a single layer of this texture.
fn mipmap(&self, level: u32) -> Option<Texture2dMultisampleMipmap>
Access a single mipmap level of this texture.
fn main_level(&self) -> Texture2dMultisampleMipmap
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 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.
