Houdini 16.5 Nodes VOP nodes

Color Map VOP node

Looks up a single sample of RGB or RGBA color from a disk image.

This operator looks up a single sample of RGB or RGBA color from a disk image. If the image does not have an alpha channel associated with it (e.g. a JPEG image) and the operator returns RGBA, the alpha component will be set to 1.

Note

This VOP uses point sampling and does not perform filtering of the texture.

Parameters

Signature

RGB or RGBA values.

Color Map

Image file used for look-up.

U

Image u-coordinate.

V

Image v-coordinate.

Wrap

Determines how the image is evaluated when the texture coordinates are outside the range 0 to 1. The options are:

Repeat

(string value repeat). The image map repeats outside the range 0 to 1. Basically, the integer component of the texture coordinate is ignored.

Streak

(string value streak). Texture coordinates are clamped to the 0 to 1 range.

Decal

(string value decal). Coordinates outside the range 0 to 1 will evaluate to the border color rather than an image color.

Border Color

Border color when Decal wrapping is used.
