Sometimes you may wish to touch-up the textures on an automatically generated 3D model. This can involve cleaning up artefacts or removing supporting structures used to hold the object when taking the photographs. In this simple example, we will show how a company logo can be easily superimposed onto part of the model.
In order to affix our company logo we need to choose the desired orientation of the model that we will then start editing from. In this example rotate the model by selecting the View Model toolbar and left drag the model until the top is visible. button from
To ensure accurate editing, make sure the model is taking up most of 3D view by zooming in using thebutton.
Pasting an image into PhotoShop
In PhotoShop care is required to ensure the image dimensions are preserved when pasting from the clipboard. You must first copy the image onto the clipboard as described. Only then can you create a new image using the menu item. The width and height fields will be automatically filled-in using the clipboard image dimensions. These should not be changed. Hit OK then select the menu item.
Once you are happy with your edits the modifications can be incorporated into the texture map in 3DSOM Pro. To do this the edited image needs to be copied onto the clipboard as a single layer and pasted into 3DSOM Pro.
First make sure the edited image is a single layered image. In PhotoShop select the menu item. In PaintShop Pro use the menu item.
Now copy the image onto the clipboard and paste into 3DSOM Pro using the button. PhotoShop users should avoid using the clipboard and should use drag and drop instead (see below).
Pasting an edited image from PhotoShop
PhotoShop will not place large images onto the clipboard. Instead you can use "drag and drop". Select the "Move" tool from the toolbar. Then simply drag the edited image from PhotoShop into the View Model Window in 3DSOM Pro. There is no need to hit the paste button.
Once the edited image is pasted (or dropped) into 3DSOM Pro the textures will be updated in a second or two. There is no requirement to rebuild the textures and in fact doing so would lose all your texture edits.
Using oblique views
The texture paste function has a protection mechanism that prevents you accidentally editing the surface textures from very oblique viewpoints (where the resolution would be poor due to foreshortening). If you are trying to edit the surface texture using a very oblique view (e.g. if the desired surface region is hidden when viewed front-on) then you will need to turn off this protection mechanism before pasting back your edits. From the right mouse menu in the 3D view select menu item to toggle the protection state.
