+
+\n You can change the representation of points in
+the 3D viewer either by selecting one of the predefined
+shapes or by loading a custom texture from an external file.
+
+- Standard point markers
+
+The Mesh module provides a set of predefined point marker shapes
+which can be used to display points in 3D viewer.
+Each standard point marker has two attributes: type (defines shape
+form) and scale factor (defines shape size).
+
+\image html point_marker_widget1.png

+<br>
+
+\image html std_point_marker.png "Mesh presentation with standard point markers"
+
+- Custom point markers
+
+It is also possible to load a point marker shape from an external file.
+This file should provide a description of the point texture as a set
+of lines; each line is represented as sequence of "0" and "1" symbols,
+where "1" symbol means an opaque pixel and "0" symbol means a
+transparent pixel. The width of the texture correspond to the length
+of the longest line in the file, expanded to the nearest byte-aligned
+value. The height of the texture is equal to the number of non-empty
+lines in the file. Note that missing symbols are replaced by "0".
+
+Here is a texture file sample:
