Point Marker

You can change the representation of the geometrical vertices 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 Geometry module provides a set of predefined point marker shapes which can be used to display vertices in 3D viewer. Each standard point marker has two attributes: type (defines shape form) and scale factor (defines shape size).

TUI Command: go.SetMarkerStd(Type, Size).

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:

00111100
00111100
11111111
11111111
11111111
11111111
00111100
00111100

TUI Command: go.SetMarkerTexture(ID).
