A colorpict is a procedurally defined color pattern, that takes its values from an image file. The values of the red, green, and blue modifier functions are multiplied with the material color values.
![[dialog]](images/colorpictdef.gif)
Function File:
This pop-up list offers all function files known to the
system for selection.
Edit...
Start the text editor that was configured in the project
preferences to edit the function file.
New...
Create a new function file, and start the text editor
to edit it.
Red/Green/Blue Function:
The functions that modify the color of the base material.
Those can be selected from the functions in the function file
as selected above.
Picture File:
The picture file where the function reads its values from.
Import...
This button invokes a file open dialog, and the selected
picture file will then be imported into the project.
y:### / x:### = #.##
The text string to the right of the import button
indicates the pixel dimensions and the aspect ratio
of the selected image. The standard "picture.cal"
function file for image mapping requires the latter
value as it's first real argument, when tiling
index variables are selected, so that it can arrange
the tiles correctly.
U Index:
V Index:
Select the variables here that the function file uses
to index into the picture. U is in hozizontal direction
of the image, V in vertical direction.
Real Arguments
Rayfront will check the selected function file to
decide how many real arguments the material definition
should supply. If this number is greater than the
mandatory arguments specifying the basic properties,
then the expected number of entry fields in the list
is made available. Supplying those arguments is
optional, but failing to do so may result in runtime
errors when the selected function relies on a specific
argument which is not set.
The Transformation page of the dialog can be used to transform the vector, possibly to bring it in alignment with the geometry of the surface the pattern modifies.
