For flat planes, see Mirror Reflection Logic.

Notice on vertical, flat planes, how the floor lines and background edges continue, straight through the plane; lines continue to the vanishing point. Polished materials like this wood cause the sharpness to blur and fade off more than will occur with chrome polished surfaces.

We have to "map" the horizontal distance, into the chrome or mirrored plane. The red ball does not sit on the bottom edge of the cube.

VERTICAL CYLINDERS AND CONES

As you progress in grey values, begin to add in color. Start with a simple, graphic background. Notice how the background color "flavors" the left part of the cylinder, and the top plane as well.

Parallel Shadow cast

Negative Light Shadow cast

Once you have the contrast and value ranges in greyscale, you can color cast your reflective surfaces with any coloration you desire. This may represent an anodized metal, chrome electro-plating, painted surface, etc.

Brass, polished bronze, gold, and like metals, are just chrome logic, in a warm golden spectrum of color.

HORIZONTAL CYLINDERS

On and inside polished surface, the landscape will invert.

Brushed metals will exhibit the same properties as polished and chrome surfaces, but with less contrast. Using Warm against Cool grey values can suggest different types of metal, such as nickel vs aluminum, or titanium vs stainless steel.
