Creating Image-based
Shaders
Image-based shaders are created from image files imported
into the Vectorworks file. Like wrapped shaders, an image-based shader
is applied to the surface of an object. See Applying and Mapping Textures for more
information. Different settings are then required depending on the type
of shader to be used with the image.
Multiple image shaders can be combined to create a realistic
texture. For example, import an asphalt image, and then add an image bump
to the asphalt. In addition, image-based shaders can be combined with
non image-based shader types for a variety of effects.
Most image-based textures are automatically compressed when
imported. Imported JPG files retain the original JPG data; all other image
files are compressed using lossless PNG format.
The Bricks shader includes its own image-selection
functionality; see Color Shaders.
Selecting
the Image for Import
To import an image for use as an image-based shader:
Create
a graphics file to be imported as a shader. In a graphics program,
save the image in a format that the Vectorworks program can import:
● BMP
● JPG
● PCT
● PNG
● PNT
● PSD
● QTI
● SGI
● TIF
● TGA
Create
a new texture as described in Creating a New Texture. From any of the four
shader component lists, select one of the image shader types.
If a
resource with an image is already present in the file, the Choose
Image dialog box opens.
Click
to show/hide the parameters.
Select
the desired image file in the Import Image Document dialog box. Click
Open.
The
next dialog box that opens depends on the type of shader, as described
in the following sections.
● Importing Images for Color Shaders
● Importing Images for Reflectivity Shaders
● Importing Images for Transparency Shaders
● Importing Images for Bump Shaders
