Rendering: Fruit Bowl Research

This term for TAFE I have my final rendering assessment. An add on from the first assessment of the banana and apple, this time it is a fruit bowl, containing; grapes, an orange, a green and a red apple, some pears and a bunch of bananas.

Below is a bunch of photos I took (not the best) as R’n’D for the assessment, this way I can document the surface properties of the fruit and keep that in mind when manipulating the Mental Ray shaders in Maya.

For the grapes, I knew prior to getting the assessment that we would need to use sub surface scattering within the shader network. A few other things I have noticed is the skin is partially transparent and that grapes are made up mostly of juice/water. So I feel to get my sub surface scattering to work more realistically, and not have my grapes ending up looking too plastic, I will need to change the index of refraction value to 1.33
I have also noticed that there is quite a distinct hot spot in places that is also, when it grows larger becomes rougher around the edges. Brown speckles are also quite common on each individual grape.

The red apple is more vibrant than the green apple, with a more variant range of colours from red, yellow, orange, green and brown. Pores on the apples skin tend to be raised instead of dimpled. Any cuts or pierced parts of the skin turn a dark brown in colour. The hot spot on the red apple is also a bit more noticeable than the green apple.

The green apple has less of a colour range than the red apple. Its colours range from greens, whites, yellows and browns. Like the red apple the pores tend to extrude rather than intrude.

The pear, like the red apple has quite a range of colour in the skin, the pores are the most distinct being brown in colour and intruding slightly into the skin. Pears have the most interesting stalk of this bunch of fruit, its twisting form is quite wrinkled and has deep crevasses.

Oranges have the hottest and sharpest of the hotspots, the skin is the most evidently riveted and ever so slightly transparent.

The banana is the most diffuse of the fruit, it still however has a hotspot, but due to the matte-ness of the skin the light is absorbed more. The skin of the banana is not perfectly smooth, but however has a sort of corrugated texture to the skin.
