Static Shape Texturing


The edit toolbar.


This tool is used for the manual texturing of shapes and individual faces. For the exact texture mapping, several modes are available. You can open the tool by drag and dropping an image file from the file navigator onto shapes, by selecting Shapes→Texture Shapes... or by starting the tool from the tool bar.

Once opened, the tool dialog stays in front of other CityEngine GUI elements, for convenient working.



The Texturing Tool provides a simple and interactive means for texture assignment


Choose a Texture Image

The image the user wants to use as a texture, may be chosen as follows:


Set Orientation

Select an orientation for the following parameters, either global or local.


Adjust Orientation

Correct the image orientation by the following three options in 'Image Transformation' group:


Mapping Mode

(see bottom of page for examples)

There are four modes with according attributes for the texture coordinate mapping, which are specified in the 'Texture Coordinates Mapping' group:

Keep current mapping

Leaves the currently set mapping (no attributes).

Stretch to polygon

This mode is used for stretching the texture across the selected face. Note that if entire shapes are selected, the texture is stretched across all present coplanar face groups.

Dimension

This mode allows the user to set the actual dimension of the used texture.

Projection

This mode is used for the texturing with an aerial image and is always projected from the top. If the image is georeferenced, it is positioned and stretched accordingly.

Scene Selection Issues

The Texturing Tool acts a little differently depending on the scene selection (colored blue):

Examples


Stretch to Polygon: using 1.8 horizontal repetitions, 1.3 vertical repetitions with Align to Top left corner


Dimension: using Absolute texture width 5.75, Absolute texture height 8.0, Align to Bottom right corner - and: Snap horizontally to bounds, so the texture fits exactly three times.
