Houdini 5.1.15 New features in Mirror SOP:
  • Mirror Point Normals if they exist
  • Mirror Quadrics
  • Support pasted surfaces
Tue. February 5, 2002
Houdini 5.1.15 A bug with the Align operation recreating point normals is fixed. Tue. February 5, 2002
Houdini 5.1.15 Fixed minor memory leaks in the majority of the cu* functions. Also fixed core dump when using cudatatype. Tue. February 5, 2002
Houdini 5.1.15 Flipbooking for COPs now acts exactly like a render - frames are shown in MPlay, the image updates per tile in a circular fashion around the last user mouse click. Tue. February 5, 2002
Houdini 5.1.14 Added initial version of Mirror SOP Mon. February 4, 2002
Houdini 5.1.14 Modified the look of the standard parameter dialog (gasp!) by flattening the top tier buttons and introducting a stow bar to encapsulate the bar containing the "Oevrride" and "Presets" buttons. That bar is stowed by default for a cleaner look (and because those buttons are not accessed all that frequently). Mon. February 4, 2002
Houdini 5.1.14 Fixed a bug in PolySplit and EdgeDivide that could cause core-dumps on bad geometry. Mon. February 4, 2002
Houdini 5.1.11 Reworded a label in the Select&Transform state at the Object (world) level to read "Link to Motion Editor" instead of "Link to CHOP Editor". Fri. February 1, 2002
Houdini 5.1.11 All tiles are now slightly rounded. Fri. February 1, 2002
Houdini 5.1.10 Fixed several bugs related to creation of channels:
  • Adding keys to a channel that has no keys now no longer crashes.
  • Spare channels now always get created with an initial channel segment.
  • When using the chadd command, if you use the -f or -t option or when creating spare channels, we now we use the user-defined initial expression function (from the channel editor preferences) instead of hardcoding "cubic()". Note that you have to open up a channel editor first for the user-defined expression to have an effect.
Thu. January 31, 2002
Houdini 5.1.10 Scripted Subnets are now known provisionally as Operator Types. Thu. January 31, 2002
Houdini 5.1.9 Moved the Desktop menu before the "Help" menu, making it part of the main menu bar at the top of the houdini window. Wed. January 30, 2002
Houdini 5.1.9 Changed the look of the Ortho/perspective icon below the 3D viewport. The overall look of the UI is softer and some of the widgets are slightly rounded. Pretty much got rid of all bold fonts. Wed. January 30, 2002
Houdini 5.1.9 .geo files can now have runs over 65535 primitives. Wed. January 30, 2002
Houdini 5.1.8 3D texture calls in VEX have changed. Arbitrary filter kernels are now supported as well as other changes. Please see online VEX documentation for details. Tue. January 29, 2002
Houdini 5.1.8 hlicense now generates Penta Codes for hkey license instead of long strings of hex. HKey can take either code format, but the penta version is preferable as it has robust error detection and notification. Ie: if you mistype a license, it will tell you WHERE you mistyped it. Tue. January 29, 2002
Houdini 5.1.8 The license manager accepts upper and lower case LICENSE, Generic, and Houdini commands. It will also properly reject mispelled instances of generic and houdini. Tue. January 29, 2002
Houdini 5.1.7 Inspection is now supported for all MPlay and Compositor display modes (Timeline and Histogram). The Timeline inspection information shows the statistics of the frame under the cursor, while the Histogram inspection shows the values of the graph. Mon. January 28, 2002
Houdini 5.1.7 A Cineon page has been added to the Compositing preferences. This contains the default Cineon parameters for all Cineon I/O. It also defines the default values of the corresponding Cineon parameters in all new File COPs and Composite output drivers.

A new environment variable has also been added to specify what the image white point is (the linear value of cineon 100% intensity) - HOUDINI_CINEON_IMAGE_WHITE.

Mon. January 28, 2002
Houdini 5.1.7 Instead of red flagging invalid division/order selections in the Grid Operation, we yellow flag and promote to a valid value. Mon. January 28, 2002
Houdini 5.1.4 Added the Line Operation which allows you to create Line primitives. Fri. January 25, 2002
Houdini 5.1.4 The Diff Bar in MPlay and the Compositor has been significanly improved:
  • In the compositor, the COP with the template flag set is always the COP to compare the display COP(s) to.
  • In MPlay, a Diff flag has been added to the Sequence Manager so image sequences can be selected in the same way as the Template flag above.
  • A 'Diff' mode has been added, in addition to 'Subtract' (diff takes the absolute difference, where 'subtract produces positive and negative values).
  • When the Diff bar is opened, diff'ing is automatically enabled.
