Muscle Shader Test
 

This is more work for the "Haemoglobin Project" that I am doing.

I knocked this up in 20 mins and the model is a test model definatley not the final one!!

for those interested this i sthe texture map i used:

yummy!

Looks good. Did you apply a bump map?

Yeah it's got a bump map on it, i tried to do a displacement map on it to get a better result but it went horribly wrong. :(

I'm still pretty happy with it as it only took 20mins to do.

whats the difference between bump and displacement? never know that

displacement adds geometry and physically moves the surface of the object being shaded where as bump only changes the colours of the surface to simulate that effect.

Best way to demonstrate is to create a sphere and apply a simple bump to it and then render and look at it's profile. You should see the sphere as normal. If you then take the same sphere and apply a displacement to it you should see the profile of the sphere being "displaced" by the effect. Bumps are quicker and generally less render time expensive however for close up stuff displacement is better (Although displacement and raytracing are not the best of friends!!! for obvious reasons!)

Hope that helps
