I'm not sure what's the matter according to the screenshot. Could you upload 
this model here so that I can make a quick test?

I see. The issue lies in the material definition in your mtl file. Open 
broccoli.mtl in a text editor, you'll see these lines:

  Kd 0.00 0.00 0.00
  ...
  Kd 0.00 0.00 0.00

A Kd statement defines the diffuse color for a material. According to Jsc3d's 
lighting equation, if the diffuse color is zero, the corresponding mesh will be 
completely dark.

Try to replace these fields with more meaningful values such as:

  Kd 0.80 0.80 0.80

And it will be ok.

To improve the quality of the redering, you may also need to add the following 
lines to the initialization section:

  viewer.setParameter('CreaseAngle', 30);
  viewer.setParameter('MipMapping', 'on');

which help to release aliasing artifacts.

Besides, it seems that your model has some faces whose vertices are not 
described in correct (counterclockwise) order. This will result in improper 
face culling. Try to repair your model using a modelling software. Both 3DSMAX 
and Blender can make it automatically.
