How is the texture of a donut created?
Our process of cooking the dough simply involves adding a spectral texture map to the object that already holds a bump-map. Our texture is a color gradient with brush stroke noise added. The colors from the gradient were sampled from actual donut photography. Next we decided to implement the ideal torus shape.
How is the deformation of a donut simulated?
A very relistic “dough” deformation can be simulated by selecting a sub-group of closely spaced vertices and either translating them or scaling them. The following is an initial result: The donut on the left is our original ideal PBRT torus.
What kind of texture mapping is used in Donut rendering?
Even when texture mapping is applied it is usually procedural, such as a wood grain, or a wrinkle in aluminum foil. Some items however, lend themselves nicely, such as a poster on a store window or in this case, a donut box: Some empty boxes for our final scene.
Is it possible to draw a donut as one object?
However if we could draw the donut as one object (like the doughball), then draw the glaze as a transparent shell (like the killeroo), then we might benifit greatly from using the Whitted integrator. If possible we must try at all costs to use the direct lighting integrator for speed.
What should the temperature of dough be when making donuts?
Dough should pull clean away from the sides of the bowl when properly developed. Dough Temperature — Ideal temperature is between 78° to 82° F (25.6° to 27.8° C). Dough temperature that is too hot will ferment too fast, have poor texture and grain and have a darker than normal color when fried.
What does it mean to ferment dough for donuts?
Fermentation — Defined as: a period of time to allow a chemical change activating the living organism (yeast or bacteria), that is, allowing it time to feed and grow, thus producing a leavening gas. Dough should be fermented in the mixing, at room temperature, and away from drafts.
What happens when you touch the dough of a donut?
When lightly touched, a properly proofed dough retains an impression formed by the finger but does not collapse. A young or underproofed dough is tough, elastic and springy, and retains no impression when touched. An old or overproofed dough retains the impression of the finger and may even collapse.
