\class QSGOpaqueTextureMaterial

127

\brief The QSGOpaqueTextureMaterial class provides a convenient way of

128

rendering textured geometry in the scene graph.

129

\inmodule QtQuick

130

\ingroup qtquick-scenegraph-materials

131

132

\warning This utility class is only functional when running with the OpenGL

133

backend of the Qt Quick scenegraph.

134

135

The opaque textured material will fill every pixel in a geometry with

136

the supplied texture. The material does not respect the opacity of the

137

QSGMaterialShader::RenderState, so opacity nodes in the parent chain

138

of nodes using this material, have no effect.

139

140

The geometry to be rendered with an opaque texture material requires

141

vertices in attribute location 0 and texture coordinates in attribute

142

location 1. The texture coordinate is a 2-dimensional floating-point

143

tuple. The QSGGeometry::defaultAttributes_TexturedPoint2D returns an

144

attribute set compatible with this material.

145

146

The texture to be rendered can be set using setTexture(). How the

147

texture should be rendered can be specified using setMipmapFiltering(),

148

setFiltering(), setHorizontalWrapMode() and setVerticalWrapMode().

149

The rendering state is set on the texture instance just before it

150

is bound.

151

152

The opaque textured material respects the current matrix and the alpha

153

channel of the texture. It will disregard the accumulated opacity in

154

the scenegraph.

155

156

A texture material must have a texture set before it is used as

157

a material in the scene graph.

/*!

Creates a new QSGOpaqueTextureMaterial.

164

165

The default mipmap filtering and filtering mode is set to

166

QSGTexture::Nearest. The default wrap modes is set to

167

\c QSGTexture::ClampToEdge.
