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

22 - Custom point markers
24 It is also possible to load a point marker shape from an external file.
25 This file should provide a description of the point texture as a set
26 of lines; each line is represented as a sequence of "0" and "1" symbols,
27 where "1" symbol means an opaque pixel and "0" symbol means a
28 transparent pixel. The width of the texture corresponds to the length
29 of the longest line in the file, expanded to the nearest byte-aligned
30 value. The height of the texture is equal to the number of non-empty
31 lines in the file. Note that missing symbols are replaced by "0".
33 Here is a texture file sample:
