Since the image used to create the texture is the same as the image used to create the model, this should be achievable. The texture would obviously be created by cutting and stitching pieces of the drawing, and mapping them to the area of the model they represent. This should be easily accomplished by making the original image(s) grayscale, then removing any brightness difference caused by colors which didn’t represent depth.Īdditionally, a good tool would also generate the UV map and texture automatically. For this the artist would need to edit the drawing once more, in order to create a grayscale bump map. Since even if cutting an alpha channel around the character makes the outline clear, that doesn’t say which parts are bumpy and which are flat. The next tricky part is knowing which areas are flat and which are round. To make the task easier for Blender, the image(s) could be modified in an image editing tool like Photoshop or GIMP… to remove the background so Blender only scans the character’s outline without other elements getting in the way. The addon would require an image of the character or object from 6 angles: Front, back, left, right, top, bottom… which in some form it would have to combine and interpret into a single 3D result. They could also scan objects or even whole rooms! My imagined solution is this: People could also take photos of themselves against a green screen, and use them to automatically scan themselves into Blender, without having to use expensive 3D scanning equipment. So an idea came to mind: What if Blender could automatically generate character and object models from images? For drawn characters, reference sheets could be used.
#Blender 3d model from photo manual
Although you can assign a background image to various camera angles, and model the initial mesh to fit its outlines, the result still isn’t always accurate and takes a lot of manual work. I was thinking about the difficulties of making 3D characters look as good as characters in drawn art, combined with the effort of modeling a character from scratch to begin with.
