@brief Base for textures |
|
|
|
Encapsulates one OpenGL texture object. See @ref Texture, @ref TextureArray, |
|
@ref CubeMapTexture, @ref CubeMapTextureArray, @ref RectangleTexture, |
|
@ref BufferTexture and @ref MultisampleTexture documentation for more |
|
information and usage examples. |
|
|
|
## WebGL restrictions |
|
|
|
@ref MAGNUM_TARGET_WEBGL "WebGL" puts some restrictions on type of data |
|
submitted to @ref Texture::setSubImage() "*Texture::setSubImage()", see its |
|
documentation for details. |
|
|
|
@anchor AbstractTexture-performance-optimization |
|
## Performance optimizations and security |
|
|
|
The engine tracks currently bound textures in all available texture units to |
|
avoid unnecessary calls to @fn_gl{ActiveTexture} and @fn_gl{BindTexture}. |
|
Texture configuration functions use dedicated highest available texture unit |
|
to not affect active bindings in user units. Texture limits and |
|
implementation-defined values (such as @ref maxColorSamples()) are cached, so |
|
repeated queries don't result in repeated @fn_gl{Get} calls. |
|
|
|
If on desktop GL and @extension{ARB,direct_state_access} (part of OpenGL 4.5) |
|
is available, @ref bind(Int) and @ref unbind(Int) use @fn_gl{BindTextureUnit}. |
|
Otherwise, if @extension{ARB,multi_bind} (part of OpenGL 4.4) is available, |
|
@ref bind(Int) and @ref unbind() uses @fn_gl{BindTextures}. Lastly, if |
|
@extension{EXT,direct_state_access} is available, @fn_gl_extension{BindNamedTexture,EXT,direct_state_access} |
|
function is used to avoid unnecessary calls to @fn_gl{ActiveTexture}. |
|
|
|
In addition, if either @extension{ARB,direct_state_access} (part of OpenGL 4.5) |
|
or @extension{EXT,direct_state_access} is available, also all texture |
|
configuration and data updating functions use DSA functions to avoid |
|
unnecessary calls to @fn_gl{ActiveTexture} and @fn_gl{BindTexture}. See |
|
respective function documentation for more information. |
|
|
|
If @extension{ARB,multi_bind} (part of OpenGL 4.5) is available, |
|
@ref bind(Int, std::initializer_list<AbstractTexture*>) and @ref unbind(Int, std::size_t) |
|
use @fn_gl{BindTextures} to avoid unnecessary calls to @fn_gl{ActiveTexture}. |
|
Otherwise the feature is emulated with sequence of @ref bind(Int)/@ref unbind(Int) |
|
calls. |
|
|
|
If either @extension{ARB,direct_state_access} or @extension{ARB,robustness} is |
|
available, image reading operations (such as @ref Texture::image()) are |
|
protected from buffer overflow. However, if @extension{ARB,direct_state_access} |
|
is not available and both @extension{EXT,direct_state_access} and |
|
@extension{ARB,robustness} are available, the robust version is preferred over |
|
DSA. |
|
|
|
To achieve least state changes, fully configure each texture in one run -- |
|
method chaining comes in handy -- and try to have often used textures in |
|
dedicated units, not occupied by other textures. First configure the texture |
|
and *then* set the data, so OpenGL can optimize them to match the settings. To |
|
avoid redundant consistency checks and memory reallocations when updating |
|
texture data, set texture storage at once using @ref Texture::setStorage() "setStorage()" |
|
and then set data using @ref Texture::setSubImage() "setSubImage()". |
|
|
|
Function @ref Texture::setStorage() "setStorage()" creates immutable texture |
|
storage, removing the need for additional consistency checks and memory |
|
reallocations when updating the data later. If OpenGL 4.2, @extension{ARB,texture_storage}, |
|
OpenGL ES 3.0 or @es_extension{EXT,texture_storage} in OpenGL ES 2.0 is not |
|
available, the feature is emulated with sequence of @ref Texture::setImage() "setImage()" |
|
calls. |
|
|
|
You can use functions @ref Texture::invalidateImage() "invalidateImage()" and |
|
@ref Texture::invalidateSubImage() "invalidateSubImage()" if you don't need |
|
texture data anymore to avoid unnecessary memory operations performed by OpenGL |
|
in order to preserve the data. If running on OpenGL ES or extension |
|
@extension{ARB,invalidate_subdata} (part of OpenGL 4.3) is not available, these |
|
functions do nothing. |
|

|
@todo all texture [level] parameters, global texture parameters |
|
@todo Add glPixelStore encapsulation |
|
@todo Texture copying |
|
@todo Move constructor/assignment - how to avoid creation of empty texture and |
|
then deleting it immediately? |
|
@todo ES2 - proper support for pixel unpack buffer when extension is in headers |
|
@todo `GL_NUM_COMPRESSED_TEXTURE_FORMATS` when compressed textures are implemented |
|
@todo `GL_MAX_SAMPLE_MASK_WORDS` when @extension{ARB,texture_multisample} is done |
|
@todo Query for immutable levels (@extension{ARB,ES3_compatibility}) |
