详细描述

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.

enum QAbstractTexture:: CubeMapFace

This enum identifies the faces of a cube map texture

常量 值 描述
Qt3DRender::QAbstractTexture::CubeMapPositiveX 0x8515 Specify the positive X face of a cube map
Qt3DRender::QAbstractTexture::CubeMapNegativeX 0x8516 Specify the negative X face of a cube map
Qt3DRender::QAbstractTexture::CubeMapPositiveY 0x8517 Specify the positive Y face of a cube map
Qt3DRender::QAbstractTexture::CubeMapNegativeY 0x8518 Specify the negative Y face of a cube map
Qt3DRender::QAbstractTexture::CubeMapPositiveZ 0x8519 Specify the positive Z face of a cube map
Qt3DRender::QAbstractTexture::CubeMapNegativeZ 0x851A Specify the negative Z face of a cube map
Qt3DRender::QAbstractTexture::AllFaces 0x851b Specify all the faces of a cube map

注意： 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.
