Houdini Main Changelogs
|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.
|Thu. May 3, 2001|
|Houdini 4.9.351||There was a bug decompressing the first tile in RAT files. This would cause a black square in the bottom left corner to occur when displaying the RAT file.||Thu. May 3, 2001|
|Houdini 4.9.350|| Added new sop expression, "xyzdist". This finds the distance to a piece of geometry giving x,y, and z coords. It is just like the pointdist, except you don't need a point. Try it out in the isosurface SOP!
Both pointdist and xyzdist are now documented to take "-1" as their primitive number, in which case they will find the closest primitive in the entire SOP rather than a specific one. A new type parameter (3) now allows these functions to return the primitive id of the closest primitive.
|Wed. May 2, 2001|
|Houdini 4.9.348||Added checkmarks and a new "Hide" entry to the context-sensitive geometry menu in the SOP viewer (ie the menu accessed with the right mouse button)||Tue. May 1, 2001|
|Houdini 4.9.348||Fixed the interactive geometry reselection for all sops whose selectors are not tied to a specific input group, such as Merge, Switch, Blend, LOD, Attribute.||Tue. May 1, 2001|
|Houdini 4.9.348||The VEX function texture3dBox() returned incorrect information if the bounding box of the 3D texture file was not a cube.||Tue. May 1, 2001|
|Houdini 4.9.345||Added Parm toolboxes and the Handle list to the COP Viewer.||Fri. April 27, 2001|
|Houdini 4.9.345||Added the Shape COP, for creating common shapes quickly.||Fri. April 27, 2001|
|Houdini 4.9.345|| Various tweaks and fixes to the display options.
