Houdini Main Changelogs
|Houdini 4.9.359|| The image3d VEX context has a new loop construct. The forpoints() loop will loop through all metaballs which have an effect at the point specified. The mattrib() and mdensity() functions work differently inside a forpoints() loop in that they will return the attribute for the metaball in question. For example, to blend the color attribute, you can do either:
vector clr = mattrib("Cd", P);
vector clr = 0;
However, the loop construct also allows users to perform their own blending functions on metaball evaluation.
Please see the online HTML VEX documentation for further information.

|Houdini 4.9.359||Fixed bug which caused crashes when manipulating the viewer handles of the Noise CHOP when it was generating Brownian or Random noise.||Fri. May 11, 2001|
|Houdini 4.9.358||Removed 1024 channels per CHOP limitation when expanding pattern strings. This also fixes crash in the Rename CHOP when trying to rename more than 1024 channels at once.||Thu. May 10, 2001|
|Houdini 4.9.357||We now draw a coloured border around parms that have handles tied to them. The border color is dark blue for the parms whose handles are visible, and dark red for invisible (ie ladder and stepladder) handles.||Wed. May 9, 2001|
|Houdini 4.9.357||omunbind no longer crashes in SOPs.||Wed. May 9, 2001|
|Houdini 4.9.357||The internal VEX optimizer has been sped up. Large VEX functions should load faster now.||Wed. May 9, 2001|
|Houdini 4.9.357||Adding the ability to type an op name in the tab menu. The list of operators will be filtered to match what was typed.||Wed. May 9, 2001|
|Houdini 4.9.357||Added handles and automatic node creation to the TimeLine view. Also added a filter mechanism to display all, just displayed, or time sensitive COPs in the timeline.||Wed. May 9, 2001|
|Houdini 4.9.356|| There are two new expression functions in Houdini:
tex() and texni()
which perform texture evaluation of disk files. These functions are similar to the pic() and picni() expression functions, but use the texture mapping code to allow for rasters which aren't 4 channel 8/16 bit data. These functions can minimize memory usage when accessing single or three channel images and can also provide access to high-dynamic range/high-precision data stored in floating point images.

|Houdini 4.9.356|| The texture engine for sampling non-RAT textures was largely re-written. Aside from minor performance improvements, the texturing code now handles images consisting of 1, 3 or 4 channels of color data which can be 8-bit, 16-bit or floating point format. Previously all images loaded were converted to 4 channel 8-bit or 16-bit rasters internally.
Please note that RAT files still provide the best quality filtering and memory usage and should be used for all texture mapping (excepting bump-mapping and shadow maps where no filtering advantages are gained).

|Houdini 4.9.355||When secure selection is OFF in the world viewer, the selection buttons on the left-hand side of the viewer are now enabled.||Mon. May 7, 2001|
|Houdini 4.9.355||Improved bone rotations (especially twisting) when converting mocap data.||Mon. May 7, 2001|
|Houdini 4.9.352||Added "Merge Operation With All Footprints" to sop viewer menu. If anyone finds footprints confusing and does not for sure what is finally exported to the object, this option should put all confusion to rest because it merges everything visible into one SOP.||Fri. May 4, 2001|
|Houdini 4.9.352||Allow quick selection and click-and-drag operations from the bone posing state and the multi-object state.||Fri. May 4, 2001|
|Houdini 4.9.352|| New options in the RMB context-sensitive menu in the SOP/OBJ viewer:
Also shuffled entries in the viewer menu and added:
|Fri. May 4, 2001|
|Houdini 4.9.352||All multi-object states can copy, paste, and delete the currently picked objects.||Fri. May 4, 2001|
|Houdini 4.9.352||All multi-object states now set object pick and current flags when selecting objects. When the selection is changed in the viewport, these changes are reflected in network editors. During a selection operation (or if secure selection is off) selection in a network editor changes the selection in the viewport. Pick scripts are run only when in the Transform state.||Fri. May 4, 2001|
|Houdini 4.9.352||There was a bug with the mattrib() function in the image3d VEX context. If the attribute didn't exist, i3dgen would core dump. If the attribute did exist, it wouldn't have been imported properly.||Fri. May 4, 2001|
|Houdini 4.9.352||Fixed bug in quad viewport mode where the bottom-right viewport was not displaying selections.||Fri. May 4, 2001|
|Houdini 4.9.351||You can now clear all the SOPs of the current object using the SOP viewer menu. Look for "Clear Current Object" in the viewer menu.||Thu. May 3, 2001|
|Houdini 4.9.351||Polysplit now allows you to branch off using SHIFT, and keeps track of the "constant bias" value between polysplit states.||Thu. May 3, 2001|
|Houdini 4.9.351|| Added two new options to the SOP viewer menu in an effort to keep visual clutter under control:
Also added (but not implemented) options to delete and hide persistent handles. These options are currently disabled, acting as a reminder for us to implement them.
|Thu. May 3, 2001|
|Houdini 4.9.351||When CPP processing was installed in parsing of the VEX Op tables, this broke loading of hip files in hscript. This has been fixed.||Thu. May 3, 2001|
|Houdini 4.9.351|| Various fixes to polyknit:
||Thu. May 3, 2001|
|Houdini 4.9.351|| When running hscript command files the execute() function didn't properly grab the output of a sourced command. Now something like:
set a = `execute("source foo.cmd")`
will work properly inside of a script.
