I would like to draw a simple line using Python script code.
I would like to draw the line from (0,0,0) to (0,0,1)
My philosophy (from what I’ve seen on the net) is: Draw a mesh plane (center at (0,0,0))
Select and delete 3 of the 4 vertices (Edit Mode)
Snap (move) the remaining vertex to the center of the plane (original placement point)
snap cursor to center
select and snap remaining vertex to cursor (now at the center)
Extrude the current vertex to (0,0,1)
I come from a CAD world, so this seems complicated for a simple object like a line, but I’m willing to adapt.
My general task is to draw “stick figures” using lines (between named points).
Being able to “name” the points would be a plus, so I can draw new lines starting from those named points when needed.
Ultimately, I would like to be able to import a spreadsheet/csv file with point data and plot the stick figures, where
each point could have a name, and the final figure would also have a name for later referencing.
Please advise if this is not the appropriate place to post this request.
[QUOTE][/QUOTE]Unfortenately I have not figured out how to update meshes from bpy.object modification. but I can awnser your question for every line use scene.post_draw.append(lambda:bge.render.drawLine(3dcoord,(r,g,b)))
For every point in you csv file, create a new object with only 1 vertex positioned at x, y, z:me = bpy.data.meshes.new(name_of_the_point)
ob = bpy.data.objects.new(name_of_the_point, me)
ob.location = x, y, z
Then for every line you need to draw between two points, create a bezier curve between the two point. One way to do it is to create a mesh with 1 edge between the two point and convert it a curve :
co1 = bpy.data.objects.get(name_of_the_point1).location.copy()
me = bpy.data.meshes.new(curve_name);
ob = bpy.data.objects.new(curve_name, me)
