3 : Perspective



good way to consider this viewpoint would be to imagine you looking up at a very tall building or perhaps looking down from a very high distance. These extreme vantage points would best be depicted using three point perspective. The main distinguishing factor present in three point perspective is in its name. One point perspective makes use of one vanishing point. Two point perspective uses two vanishing points. It should come as no surprise that three point perspective uses three vanishing points. The third vanishing point in three point perspective is not placed on the horizon line as seen with two point and one point perspective. Instead the third vanishing point is placed under or above the horizon line. Often the bottom vanishing point is placed off of the picture plane.

Like the other two forms of linear perspective, the first step is to define the horizon line. If you plan on placing the object below the horizon, be sure to draw the horizon on the top portion of the paper. If the object that you are drawing is to be placed above the horizon, be sure to place the horizon line near the bottom portion of the paper.


Next, place the third vanishing point below the intersecting lines. The closer that you place the vanishing point to the intersecting lines, the more extreme your perspective will become. If you place the third vanishing point too close to the intersecting lines, you will create unwanted distortion.


The biggest difference in three-point perspective is that there are three vanishing points (VPs). Two are along the horizon, just like two-point, but the third VP is located either above the horizon (at the zenith) or below the horizon (the nadir), depending on the area you intend to draw.


Remember that in basic one-point perspective, lines are either vertical, horizontal or recede toward the vanishing point. In two-point, lines are either horizontal or recede toward one of the two vanishing points. In three-point perspective all lines recede toward one of the three vanishing points.


To draw a simple shape in three-point perspective, start just as you would in rwo-point perspective, with a horizon line and two vanishing points as close to the edge of your page as possible. Only this time, rather than in the middle, place the horizon line close to the top of your page if the viewer will be looking down, or the bottom of your page if the viewer will be looking up.


Three point perspective drawing is an essential skill to aspiring artists. From buildings to landscapes and even still life subject matter, understanding how to draw in three point perspective will make drawing much easier!


If you have no perspective drawing knowledge what-so-ever, using 3 vanishing points can get tricky. Make sure you have a basic understanding of Two Point Perspective before you attempt to learn the drawing techniques on this page.


Three point perspective is a form of linear perspective that utilizes three vanishing points in which forms utilize each of the 3 vanishing points to convey the illusion of depth on a two-dimensional surface.


Keeping an understanding of perspective in ones mind helps an artist to appropriately size out objects. This helps artists create a realistic look of depth even though they are working on a flat piece of paper or canvas.


Now it makes sense to draw the other plane of the cube. Notice how this time the green perspective lines are being connected to the green vanishing point. Also notice that any of the vertical lines of the cube get connected to the blue vanishing point.


All of these perspective lines are converging on their appropriate vanishing point. Non of these lines are drawn parallel to each other, which is an important difference when compared to both one point perspective and two point perspective.


Once you have a row of windows drawn in proper 3 point perspective we can use their vertical lines to help us draw the rest of the windows. Take a look at the drawing below. You can see that each of the blue lines that make up the windows not only connect to the blue vanishing point but line up with each other.


Because we are seeing a large proportion of the tops of these buildings and not too much of the sides they are easy to make mistakes with. I recommend temporarily drawing these buildings outside the picture plane so that you can properly calculate where each perspective line goes.


For a quick primer on how to draw doors and windows in three point perspective have a look at the previous tutorial above on drawing buildings from a street view looking up. I go over in greater depth how to line up windows so everything looks even and realistic.


One important thing to keep in mind when shading perspective items is to hint at a light source. To do this simply make one side of each building lighter in value and another side darker. As long as you do this consistently throughout the composition your cityscape will have a realistic appeal to it.


Take a look at the lamp on the desk. Notice how the post leading up to the lamp shade is drawn to vanishing point #3. This is because that post is vertical. All vertical lines in a 3 point perspective drawing have to connect to the third vanishing point!


With all the perspective lines in place and everything cleaned up I decided to add some color. I used a simple monochromatic color scheme. I made sure to darken the values on the left sides of each object in this bedroom drawing. Why? To give the illusion of a light source and help add a touch of realism to this perspective drawing.


If you have just arrived here on this page with no three point perspective drawing experience please go back to the top of this article and start at the beginning. This article is designed for beginners who want to learn to draw properly in 3 point perspective. But everything here is in sequential order building on previous lessons.


Maat Mons is displayed in this computer generated three-dimensional perspective of the surface of Venus. The viewpoint is located 634 kilometers (393 miles) north of Maat Mons at an elevation of 3 kilometers (2 miles) above the terrain. Lava flows extend for hundreds of kilometers across the fractured plains shown in the foreground, to the base of Maat Mons. The view is to the south with the volcano Maat Mons appearing at the center of the image on the horizon and rising to almost 5 kilometers (3 miles) above the surrounding terrain. Maat Mons is located at approximately 0.9 degrees north latitude, 194.5 degrees east longitude with a peak that ascends to 8 kilometers (5 miles) above the mean surface. Maat Mons is named for an Egyptian Goddess of truth and justice. Magellan synthetic aperture radar data is combined with radar altimetry to develop a three-dimensional map of the surface. The vertical scale in this perspective has been exaggerated 10 times. Rays cast in a computer intersect the surface to crate a three-dimensional perspective view. Simulated color and a digital elevation map developed by the U.S. Geological Survey are used to enhance small-scale structure. The simulated hues are based on color images recorded by the Soviet Venera 13 and 14 spacecraft. The image was produced by the Solar System Visualization project and the Magellan Science team at the JPL Multimission Image Processing Laboratory and is a single frame from a video released at the April 22, 1992 news conference.


Note that all of these perspectives require OmniFocus 3 (Pro). Some reference specific tags and folders or rely on naming conventions. You may need to make some changes to adapt them to work with your OmniFocus setup.


To see custom perspectives in action, check out our courses, including OmniFocus 3: Beyond the Basics, Navigating Your Day with OmniFocus 3, Practical Focus with OmniFocus 3, and Mastering Reviews with OmniFocus 3.


We recommend adding a distinct icon to each of your custom perspectives. This makes them easy to identify and adds a personal touch to your OmniFocus setup. OmniFocus has a collection of built-in icons and a palette of colours to choose from. There are also some excellent third-party offerings that give you a wide array of beautifully-designed icons to draw from. These include a collection from Josh Hughes (free) and a collection from MacStories (paid). You can also drop in your own graphics, including photos and logos.


Water insecurity is a primary underlying determinant of global health disparities. While public health research on water insecurity has focused mainly on two dimensions, water access and adequacy, an anthropological perspective highlights the cultural or lifestyle dimension of water insecurity, and its implications for access/adequacy and for the phenomenology of water insecurity. Recent work in Bolivia has shown that scores on a water insecurity scale derived from ethnographic observations are associated with emotional distress. We extend this line of research by assessing the utility of a locally developed water insecurity scale, compared with standard measures of water access and adequacy, in predicting women's psychosocial distress in Ethiopia. In 2009-2010 we conducted two phases of research. Phase I was mainly qualitative and designed to identify locally relevant experiences of water insecurity, and Phase II used a quantitative survey to test the association between women's reported water insecurity and the Falk Self-Reporting Questionnaire (SRQ-F), a measure of psychosocial distress. In multiple regression models controlling for food insecurity and reported quantity of water used, women's water insecurity scores were significantly associated with psychosocial distress. Including controls for time required to collect water and whether water sources were protected did not further predict psychosocial distress. This approach highlights the social dimension of water insecurity, and may be useful for informing and evaluating interventions to improve water supplies. 041b061a72
