In this project, we learned how to draw technically and conceptual sketches. We learned about curve sketches, perspective and more. We were taught by watching videos and taking notes about what we learned. The info below is the vocabulary and the photos of my notes from the subject.
Sketching Vocab:
2D curve: a curve restricted to a flat two-dimensional plane such as a circle.
3D curve: a curve that moves across two or more planes, such as the handrail on a spiral staircase.
arc: a part of the circumference of a circle or other curve.
circle: a round plane figure whose boundary (the circumference) consists of points equidistant from a fixed point (the center).
compound curve (3-D curve): a curve unbounded by a single flat (two-dimensional plane/surface) moving freely across multiple planes in space; an example of a compound curve is the handrail of a spiral staircase.
curve: a line or outline that gradually deviates from being straight for some or all of its length.
curved surface: a nonflat surface; there are two basic types of curved surfaces: a single curved surface such as a regular cylinder and a compound curved surface such as an intertube (torus).
depth cue: cues that “trick” the human vision system into perceiving depth whether in a photograph or a sketch; these include relative size of objects on the page or screen as well as the occurrence of converging lines that move together toward single points on the horizon line.
edge: the outside limit of an object, area, or surface.
front view: in orthographic projection, front view is one of six standard views (front, back, left side, right side, top, and bottom).
ghost line: a very light and provisional line sketched lightly on paper or screen to help demarcate edges,centerlines, surfaces, planes, and contours.
ground line: the line where the picture plane and ground plane intersect.
horizon line: the line at which the earth’s surface and the sky appear to meet.
interior contour line: a light line that does not exist in reality but assists the viewer in seeing and understanding the form of an object or figure; interior contour lines are those positioned inside the object, form, or figure, such as those that define the nostrils in a figure drawing.
line: the shortest distance between two points and the physical mark that connects the points; lines have length but no breadth.
major axis: the longer axis of an ellipse that passes through the center point or foci and intersects the minor axis.
minor axis: the shorter axis of an ellipse that passes through the center point or foci and intersects the major axis.
origin: the point where something originates; most often used in sketching to refer to that point where the three primary Cartesian planes—top, front, and side—intersect.
outline: a line and/or curve used to enclose a flat shape or three-dimensional form; a silhouette is a filled outline.
parallel: a condition between lines, planes/surfaces, and objects whereby they remain consistently the same distance apart in space.
perpendicular: at an angle of 90° to a given line, plane, or surface—dormers and gables that extend perpendicular to the main roofline.
plane: a flat surface defined by a minimum of three or more joined or connected lines or curves on which a straight line could lie.
pyramid: a geometric polyhedron consisting of a base plane polygon of any number of sides, and the other faces are triangles with a common vertex—a three-sided pyramid.
shade: the relative darkness (or coolness) caused by shelter from direct sunlight; in sketching, shading occurs on surfaces directly out of line with the sun or light source.
shadow: a dark area or shape projected onto the ground plane on which an object sits, or on the surface of the object itself, produced by the intersection of the plane and the form (outlines) of the object and generated by a light source; shadows are flattened and skewed shapes in perspectival space of the object casting them.
surface: the outer most “skin” of an three-dimensional object, whether the flat planes of a cube or the curving surfaces of a cylinder or torus (intertube).
transversal: a line that passes through two lines in the same plane at two distinct points.
viewpoint: the specific orientation resulting from the position of the station point (viewer) in relation to the object or space.
vertex: a single point or the point of intersection between two or more lines or curves (plural of vertex is vertices).
3D curve: a curve that moves across two or more planes, such as the handrail on a spiral staircase.
