To get the bottom edge right you can for ex. In GIMP one must keep a spare copy or layer duplicate for a later a need to readjust.

I do not draw full cloth, only a little piece with no realistic proportions:Īs you see, I don't use GIMP because it hasn't adjustment layers. We'll see how the foldings can be made one by one in pieces without actual painting with brushes.Īt first one must make the outline shape and fill it with solid grey. Fortunately also a simpler shading can create apparent forms well enough.
#Gimp gradient map not working software#
Without 3D software the things get complex. Blender can simulate physics and find how a cloth would take its place when it was dropped over a table. There's a comment "use cloth simulation in Blender and no lofting is needed". The only possibility to make fine color and shading adjustments is to import the result as 2D image to a drawing program - GIMP, for example - and continue there manually.Īdvanced (and complex) 3D software like Blender can do even more. I selected it because I've seen the glosses on silk resemble metal. Unfortunately I have only entry level 3D software which has a few preset shading modes with very little control. Only delete or make invisible the original form curves and you have something to export.Īdvanced 3D modelling programs allow coloring, light adjustments and photorealistic materials. Before inserting the surface the smaller rings are lifted to their final elevations:Įven quite simple 3D modelling programs have function named Loft or Blend which creates a surface between curves and caps the ends if needed. The two smaller circles will be used to make the top part. The spline isn't based on any physics, it's a pure guess.
The lines and the biggest circle are drawn only to help drawing the spline which is done by clicking the points where the spline should go through. The hanging edge of the tablecloth is drawn as a curved spline. At first one must draw some lines and curves on a plane: I guess the nearest thing which does the job with effort such low as you expect is to let 3D software do the hard work (=the actual painting), you define only the geometric form and you do it quite loosely, the software decides the details. Unfortunately there's no such thing in GIMP and even less if it should know how the shading should be in your silky cloth when it's placed over the table. You hoped that something like a gradient guided by a path would do the trick. But it doesn't remove the need of seeing "how it should be". Thus painting it in software is easier than with traditional tools. In addition you have shortcuts such as gradients, color adjustments, cloning etc.(=the whole effect and adjustment repertoire). Software can make stable brush strokes regardless how shaky are painter's hands. Software allows experimenting and tweaking - you can click undo infinitely. That's definitely the way how the beginners must start their practicing. The problem of "seeing beforehand" is removed if one tries to redraw an existing image.
Its details are told in drawing and painting books and tutorials. The only way to decide it is to think the geometric forms and the light. The most difficult thing is to see beforehand where lights and shadows should be placed. No effect will do the trick, the needed shading is far too complex. Outreach through well written tutorials, presentation etc.There's a comment which tells the (not so comfortable) truth: To draw this in GIMP or other drawing and painting software you must develop some painting skills.Help test and triage bugs in the bugtracker.Alexander Prokoudine - /u/prokoudine ( LibreArts Founder) ( patreon) Ways to Assist GIMP.YouTube Channel spamming will not be tolerated.CSS help provided by /u/Cheesydude All about the GNU Image Manipulation Program
