The Fundamentals: by Taking The Principles We Have Learned So Far

An artist can master drawing spheres and ovoids by taking the principles we have learned so far another step. Spheres are the two main geometric forms that represent curvature going in two different directions. To achieve the illusions of depth and of the sphere's position in space, the artist can draw medians or centerlines that travel both horizontally and vertically around the form.

he sphere (ball) and ovoid (egg) are the two main geometric forms that represent curvature going in two different directionsup and down and side to side. Learning to render them can greatly aid your efforts to draw many organic objects. The most practical way to start drawing a sphere is to draw a circle inside a square. Find the center of each of the four sides of the square, then draw a circle that touches those four points. You now have the shape of a flat circle. (See Illustration z.) Next, visualize a sphere, which can be built out of a cube by mar1ing where the sphere touches the middle of a cubes six sides. (See Illustration ).) Note that a sphere, no matter how you view it, will always retain its original shape. To achieve the illusions of depth and of the spheres position in space, the artist can draw medians or centerlines that travel both horizontally and vertically around the form. In Illustration 4. the left-most drawing shows how one viewpoint implles that the viewers eye is looling at the exact middle of the sphere. The sphere lools flat; it does not reveal its position in space. In the middle drawing the sphere appears more three-dimensional because the vertical centerline is curved, implying that the sphere is turning. In the right-most drawing the sphere not only curves but also tips and tilts, offering the most volumetric illusion of all. The axis also explains the spheres position in space. Up untll now weve only been talking about theory, but now well put theory into practice. Get a white rubber ball, carefully inscribe vertical and horizontal centerllnes around it, and practice drawing the ball in many different positions in space. You will soon appreciate how effective such lines can be in conveying the balls orientation in space. These examples prove that it isnt the outline alone that males the formthe centerlines give the sphere a three-dimensional appearance.
