Houdini 13.0 Nodes

interface version 1

Builds a single image from a sequence, using the individual images as tiles.

...

  • A sequence of 20 images (pyro sim variations) assembled into a single image. An additional "hilite" mask is also created for some specified tile indices, and used to highlight certain tiles.

...

Note

This operator uses a texture function to load the images that might apply some additional pixel filtering. Although the difference is minimal, the results will not be pixel-perfect matches, compared to the original images.

Parameters

Source Tile Size

Resolution of a single tile to be read.

Note

The output image resolution is the Source Tile Size multiplied by Tiles X/Y.

Size Scale

An overall scale factor of the entire image.

Basename, Index Pattern, Postfix

Image file name components.

Tiles X, Y

The number of tiles.

Tile Index Offset

...

Normalize Index Channel

...

Hilite Mask Tiles

If enabled, an additional image channel will be created (named “hilite”). This will contain masks for the tiles listed in this field.

Transformations

These transformations are applied to each tile before fitting it to the output image. (This allows to crop or zoom in on a certain area on all tiles.)

To Do

  • finish this help (how to name file sequences, etc.)

  • more reasonable default filename parameters (esp. basename)

  • index/hilite channels are float32, regardless of any setting?

Release Notes
