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

32 It is also possible to load a point marker shape from an external file.
33 This file should provide a description of the point texture as a set
34 of lines; each line is represented as a sequence of "0" and "1" symbols,
35 where "1" symbol means an opaque pixel and "0" symbol means a
36 transparent pixel. The width of the texture corresponds to the length
37 of the longest line in the file, expanded to the nearest byte-aligned
38 value. The height of the texture is equal to the number of non-empty
39 lines in the file. Note that missing symbols are replaced by "0".
