[Visualpython-users] Released: VPython 4.beta1

[Jonathan B. <jbr...@ea...>]

A Windows build for Windows 2K/XP and source tarball are up on the
Sourceforge files section for visualpython:
http://sourceforge.net/project/showfiles.php?group_id=6013

I am particularly interested in what folks think of the points object -
its defaults, usability, etc.  More than one person has asked for such a
beastie in the past.

Happy Hacking!

Visual 4.beta1
================================================================================
	NEW FEATURES:
	* A new points object:
		class points(cvisual.renderable):
			property pos: Nx3 Numeric double array
			property color: Nx4 Numeric float array
			property size: double; the size of every point in the array, in
				either pixels or world-space units
			property type: "world" or "screen"; Defines whether a points object's
				size property is defined in world space or screen space
			property antialias: boolean; If true, points are rounded.
				otherwise, they are square.
		Caveats:
		if "GL_ARB_point_parameters" in scene.info():
			then type = "world" will work.
		else:
			type is silently ignored and considered to be "screen"
		There is an implementation-defined size range for either round or
		square points, which is not easily visible to client programs at this
		time.  Specifying a size outside this range will cause it to be
		silently clamped internally to whatever range that the hardware supports.

	
	BUGS FIXED:
	* The Gtk runtime shipped with VPython on Windows uses the Gtk-Wimp (Windows
		native widgets) theme by default.
	* Several DLL's in the Gtk runtime have been fixed
	* Texture data of NxM is automatically interpreted as NxMx1
	* Setting curve.blue works correctly
	* Thin curve's color is rendered correctly
	
	KNOWN ISSUES:
	* The Windows build will only run on Windows XP (Pro and Home) and 2000.
