Texture projection
By manipulating a texture projector, you can move the texture on an object. There are two types of texture projectors: planar and cylindrical.
Planar
A wireframe plane appears in the object. You can scale, rotate, and translate the plane to get the texture mapping you want.
The color at the edge of the texture image is applied to the sides of the object. In the following example, notice how the edge of the texture map determines the color of the cube.
Cylindrical
A wireframe cylinder appears around the object. You can scale, rotate, and translate it to get the texture mapping you want. It is preferable for mapping textures over cylinder and sphere shapes.
Note: You should delete the plane or the cylinder when you are satisfied, since they affect the refresh rate. Your object will keep whatever texture position it had.
To adjust texture projection:
- Select an object to which you added a texture.
- Choose Visualization > Texture Projection > Planar/Cylindrical.
A projector appears in the viewport and under the object in the World Explorer.
- Translate, rotate, and/or scale the projector. In the Parameter Editor, adjust the projector parameters.
Texture Projector Parameters
Active
|
If the texture mapping is not animated, turn off Active to improve performance.When Active is on, the system recomputes the texture mapping on every frame, even if the texture mapping does not change.
|
Projection type
|
Sets the type to planar or cylindrical.
|
Visible
|
Shows/hides the projector icon in the viewports. The projector icon does not appear in Browse mode or in the published output even if Visible is on.
|
Position
|
Sets the position of the projector relative to the object. For example, when you first apply the texture mapping, the projector is at 0 0 0, meaning that it has the same position as the object. You can also adjust the projector position, orientation, and scale interactively by dragging the projector icon.
|
Orientation
|
Sets the orientation of the projector relative to the object.
|
Scale
|
Sets the size of the projector. With a planar projection, if you increase the size of the projector, the texture image is stretched over a larger area. If you decrease Scale, the texture is repeated to cover the surface. With cylindrical projection, only Y Scale has an effect on the appearance of the texture.
|
UV Scale
|
Controls the number of repetitions of the texture. This parameter is useful with cylindrical mapping. If you increase UV Scale, the texture is repeated around the cylinder.
With the planar projection type, UV Scale serves the same purpose as the Scale. If you increase UV Scale, the texture is repeated to cover the surface.
