First, I will share with you what the drawing is about.
On my iComposer (see Image Composer) I have two images; one Material (a piano key) and a Human finger.
iComposer with Material (key) and Human (finger)
The BIG Question Mark is... what is the in-between of these two images; what is the Humaterial?
To find a satisfactory, no staggering (!), answer to this question we will investigate both images in turn, starting with the Material.
A piano key is a Solid (a 3 Dimensional object).
To simplify our research I start with a box, instead of a piano key to look at its characteristics.
|All different shadows|
As you can see the drawings, pictures, and models (I created in Blender) look at different angles of a box. Notice how the shadow informs us how the box is positioned in relation to the light source. Color for now is not important, I concentrate on Shape.
Next is the Human finger...
Conveniently, the human finger is a Solid too. It has bones inside, that make it bend. It comes to mind that a piano key bends also...!
Finger with bones inside
Before daring to draw a finger, I looked at my own fingers through my iSight camera (in nightvision) and this is how they look:
Wooow.. not only do keys 'bend' like fingers, they also come in series!
Now I know what I will strive for. I will align the bending joint of the fingers to the keys and 'smooth' the transition from finger to key - from Human to Material.
