This optional module allows you to map a photographic picture of an object on the corresponding 3D model. According to the data you have, there are two correlated ways to apply the image or texture onto the 3D model.
In the texturing module, you can:
It is also possible to adjust the texture or to manually choose which texture will be selected for each triangle, or to delineate the area where the texture will be applied. Thus, you control the mapping and improve the junctions between pictures if necessary.
Also available in the texturing module:
The texture material. This function enables you to texture a model with a pattern which will be repeated several times according to a direction. This feature is very interesting when it comes to texture an object in a homogeneous and repetitive way, such as a civil engineering structure, a wooden ground or a consumer good (the texture of a repetitive pattern can also be adjusted)...
The camera definition can be saved separately from the location and orientation. You can fix the parameters that you know such as the focal length, the lens distortion, etc. and compute only the unknown parameters like the camera origin and/or the camera orientation.
The pictures taken with fisheye lenses which have a short-length focal distance can be used for texturing, giving hemispheric projection. Reshaper automatically determines which projection model should be applied: perspective projection for standard camera images, equirectangular projection for full panoramic 360°x180° pictures or hemispheric projection for camera with fisheye lens.
Thus, it will be possible to work on the ortho-image in another software application. The calibration file places the textured image in the proper coordinate system.
Mesh coloration with 3DReshaper is a standard function which allows keeping the original colors of a 3D digitalization: from a colored point cloud.
Select both the mesh and the corresponding point cloud and launch the command.
