Here is a small tutorial which will tell you how to create a sphere using GIMP. Ok so here we go.
- Start with a small blank gimp canvas. Around 300×300 px
- Using the Elliptical Select Tool , select a circular region. To select a circular region, in the options of the Elliptical select tool, Fixed — Aspect Ratio, this will allow you to do a circular select. See IMAGE 1..
- Now select a color for your sphere. I have chosen a dark green.
- Next select the Blend Tool ( IMAGE 2) for gradient fill. In this select the Shape as Radial. See IMAGE 2.
- Change the direction of the gradient by clicking the check box next to the gradient. See IMAGE 2
- In the selected circular area, select a point in it using the gradient tool and drag it diagonally. See IMAGE 3.
Try out different starting points for the gradient fill. You will get different effect for the sphere.
- You sphere should be ready now. See IMAGE 4.
- To make it look a more real, drop a perspective shadow to it using the shadow filter. Filters — Light and Shadow — Perspective. You will probably need to change the angle according to your requirements so that the shadow falls opposite to the light, i.e the bright area on the sphere. See Image 5.
