详细描述

A base class to be used to provide textures.

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.

enum QAbstractTexture:: ComparisonFunction

enum QAbstractTexture:: ComparisonMode

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.
