Graphics

Draw graphics primitives to the render window. This module is pretty useless in vmd-python without EGL support.

Graphics primitives

Here are all of the simple shapes you can draw:

cone	Draws a cone.
cylinder	Draws a cylinder
line	Draw a line between the given vertices
point	Draw a point at the given vertex
sphere	Draws a sphere
text	Draw text
triangle	Draws a triangle
trinorm	Draws a triangle with given vertices and vertex normals

Manipulating graphics primitives

listall	List all drawn graphics objects on a given molecule
replace	Delete a graphics object and have the next element replace this one.
delete	Deletes a specified graphics object, or all graphics at a given molid
info	Describe a graphics object with given index

Changing the style of graphics

VMD draws graphics in a “stack” of commands that are applied in order. Instead of setting the material or color for individual graphics primitives, the color or material is defined as a command put on the stack, then all subsequent primitives will be drawn with that style until a new color or material is set.

color	Set color for subsequent graphics primitives in this molecule.
material	Set material for all graphics in this molecule
materials	Turns materials on or off for subsequent graphics primitives.

The following code will draw a red cylinder, then a blue sphere:

from vmd import molecule, graphics

drawmol = molecule.new(name="Drawings")
graphics.color(drawmol, 1)
cylinder_id = graphics.cylinder(drawmol, (0,0,0), (0,1,0), filled=True)
graphics.color(drawmol, 0)
sphere_id = graphics.sphere(drawmol, (0,0,0), radius=0.3)
