103 | \class QSGVertexColorMaterial | - | ||||||
104 | \brief The QSGVertexColorMaterial class provides a convenient way of rendering per-vertex | - | ||||||
105 | colored geometry in the scene graph. | - | ||||||
106 | - | |||||||
107 | \inmodule QtQuick | - | ||||||
108 | \ingroup qtquick-scenegraph-materials | - | ||||||
109 | - | |||||||
110 | \warning This utility class is only functional when running with the OpenGL | - | ||||||
111 | backend of the Qt Quick scenegraph. | - | ||||||
112 | - | |||||||
113 | The vertex color material will give each vertex in a geometry a color. Pixels between | - | ||||||
114 | vertices will be linearly interpolated. The colors can contain transparency. | - | ||||||
115 | - | |||||||
116 | The geometry to be rendered with vertex color must have the following layout. Attribute | - | ||||||
117 | position 0 must contain vertices. Attribute position 1 must contain colors, a tuple of | - | ||||||
118 | 4 values with RGBA layout. Both floats in the range of 0 to 1 and unsigned bytes in | - | ||||||
119 | the range 0 to 255 are valid for the color values. | - | ||||||
120 | - | |||||||
121 | \note The rendering pipeline expects pixels with premultiplied alpha. | - | ||||||
122 | - | |||||||
123 | QSGGeometry::defaultAttributes_ColoredPoint2D() can be used to construct an attribute | - | ||||||
124 | set that is compatible with this material. | - | ||||||
125 | - | |||||||
126 | The vertex color material respects both current opacity and current matrix when | - | ||||||
127 | updating it's rendering state. | - | ||||||
