In this form of perspective, forms in the distance are depicted as smaller in size, though parallel lines do not come together.

Group of answer choices
a. one-point perspective
b. two-point perspective
c. atmospheric perspective
d. isometric perspective

The form of perspective being described here is where forms in the distance are depicted as smaller in size, but parallel lines do not come together. To identify the correct answer choice, let's break down each option and identify which one matches the given description.

a. One-point perspective: One-point perspective is a drawing technique where all lines converge at a single vanishing point on the horizon line. This does not match the given description since it mentions that parallel lines do not come together.

b. Two-point perspective: Two-point perspective is a drawing technique where two vanishing points are used on the horizon line, allowing for parallel lines to converge towards these points. Again, this doesn't fit the given description, as it confirms that parallel lines don't come together.

c. Atmospheric perspective: Atmospheric perspective is a technique used in visual art where objects in the distance are depicted with less detail, decreased saturation, and changes in color. While this technique does address the aspect of distant objects appearing smaller in size, it doesn't mention anything about parallel lines.

d. Isometric perspective: Isometric perspective is a drawing technique where parallel lines remain parallel and there is no vanishing point. This contradicts the given description, as it explicitly states that parallel lines do not come together.

Based on the analysis above, none of the answer choices fully matches the description. However, the closest option that incorporates the concept of distant objects appearing smaller in size without the convergence of parallel lines is "atmospheric perspective."
