Oblique and Isometric

let's clarify those terms.

Oblique and isometric are both types of pictorial projections used to represent three-dimensional objects in two dimensions. They differ in how they show depth and angles.

1. Oblique Projection:

   • In an oblique projection, one face of the object is shown parallel to the picture plane (i.e., it looks flat, like a normal 2D drawing).
   • Lines that are perpendicular to this face are drawn at an angle (often 30° or 45°) to represent depth.
   • Angles on the parallel face are preserved, but angles on the receding lines are distorted.
   • Distances along the receding lines are often foreshortened (drawn shorter than they actually are) to make the drawing look more realistic.

2. Isometric Projection:

   • In an isometric projection, no face of the object is parallel to the picture plane. Instead, a corner of the object is typically pointed towards the viewer.
   • The three axes (length, width, height) are drawn at equal angles (120°) to each other.
   • All three axes are foreshortened by the same amount, meaning angles and lengths are distorted, but in a consistent way.
   • Angles within the object are not preserved. For example, a square face will appear as a parallelogram.
   • It gives a good sense of the object's overall form and is often used in technical drawings and video games.
