Detailed Description

The QAbstractTexture class shouldn’t be used directly but rather through one of its subclasses. Each subclass implements a given texture target (2D, 2DArray, 3D, CubeMap …) Each subclass provides a set of functors for each layer, cube map face and mipmap level. In turn the backend uses those functor to properly fill a corresponding OpenGL texture with data. It is expected the functor does as minimal processing as possible so as not to slow down textures generation and upload. If the content of a texture is the result of a slow procedural generation process, it is recommended not to implement this directly in a functor.

All textures are unique. If you instantiate twice the same texture this will create 2 identical textures on the GPU, no sharing will take place.

class CubeMapFace

This enum identifies the faces of a cube map texture

Constant

Description

Qt3DRender.QAbstractTexture.CubeMapPositiveX

Specify the positive X face of a cube map

Qt3DRender.QAbstractTexture.CubeMapNegativeX

Specify the negative X face of a cube map

Qt3DRender.QAbstractTexture.CubeMapPositiveY

Specify the positive Y face of a cube map

Qt3DRender.QAbstractTexture.CubeMapNegativeY

Specify the negative Y face of a cube map

Qt3DRender.QAbstractTexture.CubeMapPositiveZ

Specify the positive Z face of a cube map

Qt3DRender.QAbstractTexture.CubeMapNegativeZ

Specify the negative Z face of a cube map

Qt3DRender.QAbstractTexture.AllFaces

Specify all the faces of a cube map

Note

AllFaces should only be used when a behavior needs to be applied to all the faces of a cubemap. This is the case for example when using a cube map as a texture attachment. Using AllFaces in the attachment specfication would result in all faces being bound to the attachment point. On the other hand, if a specific face is specified, the attachment would only be using the specified face.
