Line Projections in Descriptive Geometry

Oblique Line Projections

For oblique line projections, both the horizontal projection (r1) and the vertical projection (r2) intersect at the reference line (LT).

Frontal Line Projections

A frontal line is straight and parallel to the Vertical Plane (PV). Its horizontal projection (r1) is always parallel to the reference line (LT).

Lines Parallel to the Reference Line (LT)

For lines parallel to the reference line (LT), both horizontal (r1) and vertical (r2) projections are parallel to the LT.

Vertical Line Projections

A vertical line is perpendicular to the Horizontal Plane (PH). Its vertical projection (r2) is perpendicular to the reference line (LT).

Edge View Projections (Perpendicular to PV)

When a straight... Continue reading "Principles of Orthographic Projections: Lines and Planes in Descriptive Geometry" »

Color Fundamentals

Tone

Tone defines the very quality that has color.

Value

Value refers to when each color or tone of the color wheel is mixed with bright white or black to darken or lighten it.

Saturation

This concept represents the purity or intensity of a particular color, its brightness or dullness.

Color Mixing

Additive Mixture

It is so named because it is produced by adding the primary colors, resulting in white.

Subtractive Mixture

This is the mix where the primary subject is involved. The sum of the three primaries produces a gray or brown color, almost black.

Complementary colors are those that are opposite on the color wheel. When you mix two complementary colors, you are mixing the three primaries.

Tone Revisited

When using various color tones,... Continue reading "Understanding Color Theory: Tone, Value, and Contrast" »

Visual Elements: Point, Line and Texture

The point is the smallest visual element. It is a shape and size; this configuration has texture and color as an expressive element. A point can be organized into groups with volume effects and textures.

The line is another basic element of visual expression and is defined as the mark that traces a point across a surface. It produces vertical lines of balance and lifting, while the horizontal produces a visual sensation of calm and relaxation.

Level is defined by its shape, size, color, direction and texture. Contrast, color, size and texture produce overlays and perceptual differences.

Texture is the appearance of a plastic surface: natural texture is present on the surface of elements of nature; structure... Continue reading "Visual Elements and Color Theory Fundamentals" »

Types of Map Projections by Preserved Dimension

1. Equidistant Projections
These projections preserve distances along specific directions, typically along straight lines known as automecoic lines. Linear deformation occurs in other directions. The linear anamorphosis, calculated as the ratio of the projected distance to the true distance, equals 1 along automecoic lines. Equidistant projections are useful for measuring distances from a central point.
2. Conformal Projections
These projections preserve angles between intersecting curves and lines. The angular anamorphosis represents the difference between the angle on the sphere and the corresponding angle on the map. Conformal projections are commonly used for nautical charts, often employing parallel... Continue reading "Map Projections: Dimensions, Geometry, and Classifications" »
