The standard syntax must be changed according to these rules: - OpenGL constants: "GL" prefix and underscore character '_' must be removed; the command must be written in lowercase.
Example:
GL_COLOR_MATERIAL -> colormaterial
OpenGL functions: "GL" prefix must be removed and the command written in lowercase. Pass parameters as list, without using parentheses ()
Example:
glBegin(GL_LINES) -> glbegin lines

- register <tclfunc> Register a Tcl procedure to be invoked automatically when redrawing the scene. It returns a handle to unregister.
Example:
| Code Block |
|---|
proc MyRedrawProcedure { } { ...body... }
set id [GiD_OpenGL register MyRedrawProcedure] |
