Explanation

Orthographic projection is a method of representing three-dimensional objects in two dimensions, typically using multiple views (top, front, side) to show the object's geometry.

It is widely used in technical drawings and engineering for precise, scale representations of objects.

Explanation

When warm, moist air inside the car meets the cold glass, condensation forms.

This happens because the glass surface is cooler than the dew point of the moist air.

Explanation

Salt is commonly included, not excluded, in most homemade modeling clay recipes.

A proper grip ensures better accuracy and fluidity in creating art.

Explanation

The picture plane is an imaginary flat surface on which a 2D drawing is made, like a canvas or drawing sheet.

It represents the surface through which the viewer sees the 3D object projected into a 2D image.
