Learn how to draw a sphere with all the elements needed to end up with something realistic. Drawing the perfect sphere using a pencil can be quite challenging. Using a vector software to do so is relatively easy. In fact, most application can help you create a sphere like the one below in just a few seconds.
There are a few things you can do to add more realism to your illustration. I will show you a few basic tips on how to create the perfect sphere and I will also give you a few examples of images that are not necessarily considered being perfect spheres.
Indeed, this cannot be considered a sphere. No shadows, no depth and no volume are visible on this illustration. The object is flat and everything in this image is in two dimensions. Let's see how you can easily simulate a 3D object using only 2D elements.
The easiest way to create a 3D object using only 2D shapes is to add a highlight on the circle using an oval shape like shown below. Of course, the effect is pretty basic and it can only be useful if you don't have access to a gradient fill tool or simply want to use this particular style in your project.
At first, this might look like a cool sphere. After all, midtones are visible throughout the illustration and the bottom of the object is darker while the top is brighter. However, this sphere was done with a gradient fill tool (which is good), but using a linear fill (which is not good).
Although the result is cool, the 3D aspect of this image is not accurate. Something is missing to create the perfect sphere and a small modification is needed to end up with the desired result.
Below, you can see the perfect sphere also done with the gradient fill tool. This time, a circular fill was used to create this cool image. Here are the five things you need to see in a sphere in order to illustrate this object properly:
Don't hesitate to modify the luminosity, position and color of the light source if needed. Once you start playing with these elements, possibilities are virtually endless. Like I said earlier, learning how to draw a sphere manually is feasible, but it can be more challenging and difficult. Have fun! :)
