Detailed Description
The QSGOpaqueTextureMaterial class provides a convenient way of rendering textured geometry in the scene graph.
Warning: 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() and 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.
Member Function Documentation
QSGOpaqueTextureMaterial::QSGOpaqueTextureMaterial()
Creates a new QSGOpaqueTextureMaterial.
The default mipmap filtering and filtering mode is set to QSGTexture::Nearest. The default wrap modes is set to QSGTexture::ClampToEdge.
QSGTexture::Filtering QSGOpaqueTextureMaterial::filtering() const
Returns this material's filtering mode.
The default filtering is QSGTexture::Nearest.
See also setFiltering().
QSGTexture::WrapMode QSGOpaqueTextureMaterial::horizontalWrapMode() const
Returns this material's horizontal wrap mode.
The default horizontal wrap mode is QSGTexutre::ClampToEdge.
See also setHorizontalWrapMode().
QSGTexture::Filtering QSGOpaqueTextureMaterial::mipmapFiltering() const
Returns this material's mipmap filtering mode.
The default mipmap mode is QSGTexture::Nearest.
See also setMipmapFiltering().
void QSGOpaqueTextureMaterial::setFiltering(QSGTexture::Filtering filtering)
Sets the filtering to filtering.
The filtering mode is set on the texture instance just before the texture is bound for rendering.
See also filtering().
void QSGOpaqueTextureMaterial::setHorizontalWrapMode(QSGTexture::WrapMode mode)
Sets the horizontal wrap mode to mode.
The horizontal wrap mode is set on the texture instance just before the texture is bound for rendering.
See also horizontalWrapMode().
void QSGOpaqueTextureMaterial::setMipmapFiltering(QSGTexture::Filtering filtering)
Sets the mipmap mode to filtering.
The mipmap filtering mode is set on the texture instance just before the texture is bound for rendering.
If the texture does not have mipmapping support, enabling mipmapping has no effect.
See also mipmapFiltering().
void QSGOpaqueTextureMaterial::setTexture(QSGTexture *texture)
Sets the texture of this material to texture.
The material does not take ownership of the texture.
See also texture().
void QSGOpaqueTextureMaterial::setVerticalWrapMode(QSGTexture::WrapMode mode)
Sets the vertical wrap mode to mode.
The vertical wrap mode is set on the texture instance just before the texture is bound for rendering.
See also verticalWrapMode().
QSGTexture *QSGOpaqueTextureMaterial::texture() const
Returns this texture material's texture.
See also setTexture().
QSGTexture::WrapMode QSGOpaqueTextureMaterial::verticalWrapMode() const
Returns this material's vertical wrap mode.
The default vertical wrap mode is QSGTexutre::ClampToEdge.
See also setVerticalWrapMode().
