Showing Draw in Action

Draw creates an oversized and antialiased OpenGL image using the current window. It's like Ray but not ray traced. Also, as now with Ray the oversized images are scaled and shown in the viewer window. As Draw doesn't ray trace the shadows of the scene, it is far faster than ray.

Usage

draw [ width [, height [, antialias ]]]

Examples

draw 1600

will create an 1600-pixel wide image with an aspect ratio equal to that of the current screen. 

draw 2000, 1500, 0

will create a 2000 by 1500 pixel image with antialiasing disabled 

draw 600, 400, 2

will create a 600 by 500 pixel image with maximum (16X) antialiasing

Match ray tracing appearance

Since PyMOL 1.6, all "line"-type representations can be rendered as cylinders if shaders are available and all *_as_cylinders settings are set. Example: 

set line_as_cylinders
set nonbonded_as_cylinders
set ribbon_as_cylinders
set mesh_as_cylinders
set dash_as_cylinders
set render_as_cylinders
draw 3000, 2000

Notes

This is a quick alternative to ray tracing with antialiasing enabled by default.

Note that image size and antialiasing may be limited in some cases due to OpenGL hardware limits, such as screen size. For example, high-end ATI and NVidia cards max out at 4096 x 4096.
