You can change the representation of points in
|
2012-08-09 16:03:55 +06:00
|
|
|
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 the 3D viewer.
|
|
|
|
|
Each standard point marker has two attributes: type (defines shape
|
|
|
|
|
form) and scale factor (defines shape size).

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 a 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 corresponds 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".
|
|
|
|
|
|
|
|
