This filter maps a picture to an object (plane, sphere, box or cylinder).
This preview has several possibilities:
- Preview!
-
Preview is automatic for some options but you will have to press this button to update Preview after modifying many other parameters.
When mouse pointer is on Preview and the Light tab is selected, it takes the form of a small hand to grab the blue point which marks light source origin and to displace it. This blue point may not be visible if light source has negative X and Y settings in the Light tab.
- Zoom out, Zoom in
-
Zoom buttons allow you to enlarge or to reduce image in Preview. Their action is limited, but may be useful in case of a large image.
- Show wireframe
-
Puts a grid over the preview to make displacements and rotations more easy. Works well on a plan.
- Update preview live
-
To have preview working as usual.
- Map to
-
This drop-down list allows you to select the object the image will be mapped on. It can be a Plane, a Sphere, a Box or a Cylinder.
- Transparent background
-
This option makes image transparent around the object. If not set, the background is filled with the current background color.
- Tile source image
-
When moving Plane object and displacing it with Orientation tab options, a part of the image turns empty. By checking the Tile source image, source image copies will fill this empty space in. This option seems not to work with the other objects.
![[Not]](images/note.png)
Not This option works with “Plane” only.
- Create new image
-
When this option is checked, a new image is created with the result of filter application, so preserving the original image.
- Antialiasing
-
Check this option to conceal this unpleasant aliasing effect on borders. When checked, this option lets appear two settings:
- Depth
-
Defines anti-aliasing quality, to the detriment of execution speed.
- Threshold
-
Defines anti-aliasing limits. Anti-aliasing stops when value difference between pixels becomes lower than this set value.
- Light Settings
-
- Light source type
-
In this drop-down list, you can select among Point light, Directional light and No light.
- Light source color
-
Press this button to open the Color Selector dialog.
- Position
-
If “Point light” is selected, you can control there light source Position (the blue point), according to X, Y and Z coordinates.
If “Directional light” is selected, these X, Y and Z parameters control the “Direction vector” (effect is not evident).
- Viewpoint Position
-
When Light Source Type is set to "Point Light", changing the X, Y, and Z values moves the "viewer" closer to or further from the object in those directions.
Note that this will not visually affect images set to "Plane" in the Map To field.
- First Axis, Second Axis
-
When Map To is set to "Plane", changing the X, Y, and Z values simulates the effect of tilting the plane on the Y and Z axes. This impacts how the Material tab settings affect the render.
- Position
-
These three sliders and their input boxes allows you to vary object position in image, according to the X, Y, Z coordinates of the object upper left corner.
- Rotation
-
These three sliders make the object rotate around X, Y, Z axes respectively.
- Intensity Levels
-
- Ambient
-
Amount of color to show where no light falls directly.
- Diffuse
-
Intensity of original color when lit by a light source.
- Reflectivity
-
- Diffuse
-
Higher values make object reflect more light (looks brighter).
- Specular
-
Controls how intense the highlights will be.
- Highlight
-
Higher values make the highlights more focused.
This tab appears only when you select the Sphere object.
- Size
-
- Radius
-
The radius ratio in comparison to the image size.
This tab appears only when you select the Box object.
- Map Images to Box Faces
-
Select an image for every face of the box. These images must be present on your screen when you call the Map Object filter.
- Scale
-
These X, Y, Z sliders allow you to change the size of every X, Y, Z dimension of the box.
This tab appears only when you select the Cylinder object.
- Images for the Cap Faces
-
Select an image for every face of the cylinder. Images must be present on your screen when you call the Map Object filter.
- Size
-
- Radius
-
This slider and its input boxes let you control the Cylinder diameter. Unfortunately, this setting works on the image mapped onto the cylinder and resamples this image to adapt it to the new cylinder size. It would be better to have the possibility of setting size cylinder before mapping so that we could map a whole image.
- Length
-
Controls cylinder length.
