OpenGL data files, *.OGL

The OpenGL Graphics window requires additional data (see OpenGL window dialog) stored in *.OGL files.

Data structure:

• File ID string (Current version: " CHOGL Version 1.1")

• Colors of the XYZ axes (3 integer values in the range 0:235)

• Line widths of the XYZ axes (3 integer values, 1 for thin lines)

• Lengths of the XYZ axes (3 real values)

• Colors of the grid lines (3 integer values in the range 0:235)

• Line widths of the grid lines (3 integer values, 1 for thin lines)

• Length of the expansion markers (1 real value)

• Number of frames for movies, increment Delta of the phase angle for movies without directives (1 integer, 1 real value)

• Initial window size in pixels (2 integer values, pixel size in x and y directions)

• Coordinates of the look from point (3 real values, Cartesian coordinates)

• Coordinates of the look at point (3 real values, Cartesian coordinates)

• Perspective data: Vertical view angle,  Aspect ratio of view angles,  Near plane location,  Far plane location (4 real values)

• Number of field tubes (1 integer value)

• LOOP i=1, Number of field tubes

•     Start point (x,y,z), radius, step (5 real values)

•     Number of lines, steps, grid color, inside color, outside color (5 integer values, color numbers within the range 0...235)
