详细描述

QSGOpaqueTextureMaterial class provides a convenient way of rendering textured geometry in the scene graph.

警告: This utility class is only functional when running with the OpenGL backend of the Qt Quick scenegraph.

The opaque textured material will fill every pixel in a geometry with the supplied texture. The material does not respect the opacity of the QSGMaterialShader::RenderState , so opacity nodes in the parent chain of nodes using this material, have no effect.

The geometry to be rendered with an opaque texture material requires vertices in attribute location 0 and texture coordinates in attribute location 1. The texture coordinate is a 2-dimensional floating-point tuple. The QSGGeometry::defaultAttributes_TexturedPoint2D returns an attribute set compatible with this material.

The texture to be rendered can be set using setTexture (). How the texture should be rendered can be specified using setMipmapFiltering (), setFiltering (), setHorizontalWrapMode () 和 setVerticalWrapMode (). The rendering state is set on the texture instance just before it is bound.

The opaque textured material respects the current matrix and the alpha channel of the texture. It will disregard the accumulated opacity in the scenegraph.

A texture material must have a texture set before it is used as a material in the scene graph.
