QOpenGLTexture ¶

概要 ¶

详细描述 ¶

QOpenGLTexture makes it easy to work with OpenGL textures and the myriad features and targets that they offer depending upon the capabilities of your OpenGL implementation.

The typical usage pattern for QOpenGLTexture is

• Instantiate the object specifying the texture target type

• Set properties that affect the storage requirements e.g. storage format, dimensions

• Allocate the server-side storage

• Optionally upload pixel data

• Optionally set any additional properties e.g. filtering and border options

• Render with texture or render to texture

In the common case of simply using a QImage as the source of texture pixel data most of the above steps are performed automatically.

// Prepare texture
QOpenGLTexture *texture = new QOpenGLTexture(QImage(fileName).mirrored());
texture->setMinificationFilter(QOpenGLTexture::LinearMipMapLinear);
texture->setMagnificationFilter(QOpenGLTexture::Linear);
...
// Render with texture
texture->bind();
glDrawArrays(...);
											

注意： QImage is mirrored vertically to account for the fact that OpenGL and QImage use opposite directions for the y axis. Another option would be to transform your texture coordinates.

class QOpenGLTexture ( target ) ¶

QOpenGLTexture(image[, genMipMaps=GenerateMipMaps])

param image

QImage

param target

Target

param genMipMaps

MipMapGeneration

创建 QOpenGLTexture object that can later be bound to target .

This does not create the underlying OpenGL texture object. Therefore, construction using this constructor does not require a valid current OpenGL context.

创建 QOpenGLTexture object that can later be bound to the 2D texture target and contains the pixel data contained in image . If you wish to have a chain of mipmaps generated then set genMipMaps to true (this is the default).

This does create the underlying OpenGL texture object. Therefore, construction using this constructor does require a valid current OpenGL context.

PySide2.QtGui.QOpenGLTexture. allocateStorage ( pixelFormat , pixelType ) ¶

参数

• pixelFormat – PixelFormat

• pixelType – PixelType

Allocates server-side storage for this texture object taking into account, the format, dimensions, mipmap levels, array layers and cubemap faces.

Once storage has been allocated it is no longer possible to change these properties.

If supported QOpenGLTexture makes use of immutable texture storage. However, if immutable texture storage is not available, then the specified pixelFormat and pixelType will be used to allocate mutable storage; note that in certain OpenGL implementations (notably, OpenGL ES 2) they must perfectly match the format and the type passed to any subsequent setData() 调用。

Once storage has been allocated for the texture then pixel data can be uploaded via one of the setData() overloads.

PySide2.QtGui.QOpenGLTexture. allocateStorage ( ) ¶

Allocates server-side storage for this texture object taking into account, the format, dimensions, mipmap levels, array layers and cubemap faces.

Once storage has been allocated it is no longer possible to change these properties.

If supported QOpenGLTexture makes use of immutable texture storage.

Once storage has been allocated for the texture then pixel data can be uploaded via one of the setData() overloads.

注意

If immutable texture storage is not available, then a default pixel format and pixel type will be used to create the mutable storage. You can use the other overload to specify exactly the pixel format and the pixel type to use when allocating mutable storage; this is particulary useful under certain OpenGL ES implementations (notably, OpenGL ES 2), where the pixel format and the pixel type used at allocation time must perfectly match the format and the type passed to any subsequent setData() 调用。

PySide2.QtGui.QOpenGLTexture. create ( ) ¶

返回类型

bool

Creates the underlying OpenGL texture object. This requires a current valid OpenGL context. If the texture object already exists, this function does nothing.

Once the texture object is created you can obtain the object name from the textureId() function. This may be useful if you wish to make some raw OpenGL calls related to this texture.

Normally it should not be necessary to call this function directly as all functions that set properties of the texture object implicitly call on your behalf.

返回 true if the creation succeeded, otherwise returns false .

PySide2.QtGui.QOpenGLTexture. createTextureView ( target , viewFormat , minimumMipmapLevel , maximumMipmapLevel , minimumLayer , maximumLayer ) ¶

参数

• target – Target

• viewFormat – TextureFormat

• minimumMipmapLevel – int

• maximumMipmapLevel – int

• minimumLayer – int

• maximumLayer – int

返回类型

QOpenGLTexture

Attempts to create a texture view onto this texture. A texture view is somewhat analogous to a view in SQL in that it presents a restricted or reinterpreted view of the original data. Texture views do not allocate any more server-side storage, insted relying on the storage buffer of the source texture.

Texture views are only available when using immutable storage. For more information on texture views see http://www.opengl.org/wiki/Texture_Storage#Texture_views .

target argument specifies the target to use for the view. Only some targets can be used depending upon the target of the original target. For e.g. a view onto a Target1DArray texture can specify either Target1DArray or Target1D but for the latter the number of array layers specified with minimumLayer and maximumLayer must be exactly 1.

Simpliar constraints apply for the viewFormat . See the above link and the specification for more details.

minimumMipmapLevel , maximumMipmapLevel , minimumLayer ，和 maximumLayer arguments serve to restrict the parts of the texture accessible by the texture view.

If creation of the texture view fails this function will return 0. If the function succeeds it will return a pointer to a new QOpenGLTexture object that will return true 从其 isTextureView() 函数。
