This rendering example creates textured objects with Tiffany Blue coloration. It shows how one might render:

• Inset ceiling lights
• Area lights
• Textures - both hard-coded and image-based

By default, this demo outputs a grainy low-resolution rendering (which takes a minute or two):

Raising the quality and resolution is as simple as modifying these lines:

NumSamples:           200,
MinSamples:           200,
MaxStddev:            0.05,

and this line:

img := render3d.NewImage(200, 200)

Simply increase NumSamples to maybe 100000, increase MinSamples to 10000, decrease MaxStddev to something like 0.02 (lower values mean less noise), and increase the resolution from 200x200 to whatever you want. Here's an example HD rendering at 800x800:
