pymel.core.rendering.iprEngine

iprEngine(*args, **kwargs)

Command to create or edit an iprEngine. A iprEngine is an object that watches for changes to shading networks and automatically reshades to generate an up-to-date image.

Flags:
Long name (short name) Argument Types Properties
copy (cp) unicode ../../../_images/edit.gif
 

Copies the deep raster file, as well as its related files, to the new location.Flag can appear in Create mode of commandFlag can have multiple arguments, passed either as a tuple or a list.

defineTemplate (dt) unicode ../../../_images/create.gif
 

Puts a command in a mode where any other flags and args are parsed and added to the command template specified in the argument. They will be used as default arguments in any subsequent invocations of the command when templateName is set as the current template.

diagnostics (dig) bool  
   
estimatedMemory (mem) bool ../../../_images/query.gif
 
Displays the estimated memory being used by IPR.
exists (ex) bool ../../../_images/create.gif
 
Returns true|false depending upon whether the specified object exists. Other flags are ignored.
iprImage (ipr) unicode ../../../_images/create.gif ../../../_images/query.gif ../../../_images/edit.gif
 
Specify the ipr image to use.
motionVectorFile (mvf) bool ../../../_images/query.gif
 
Returns the name of the motion vector file used by IPR.
object (obj) PyNode ../../../_images/create.gif ../../../_images/query.gif ../../../_images/edit.gif
 
The objects to be tuned.
region (r) int, int, int, int ../../../_images/create.gif ../../../_images/query.gif ../../../_images/edit.gif
 
The coordinates of the region to be tuned. The integers are in the sequence left bottom right topor x1,y2 x2,y2
relatedFiles (rel) bool ../../../_images/query.gif
 
Returns the names for the related files, e.g, the non-glow-non-blur image, the motion vector file, and the depth-map files.
releaseIprImage (rii) bool ../../../_images/edit.gif
 
The ipr image should be released and memory should be freed.
resolution (res) bool ../../../_images/query.gif
 
The width and height of the ipr file.
scanlineIncrement (sli) unicode ../../../_images/create.gif ../../../_images/query.gif ../../../_images/edit.gif
 

Set the scanline increment percentage. If the height of the region being update is 240 pixels, and the scanlineIncrement is 10% then the image will refresh blocks of 24 scanlines.

showProgressBar (spb) bool ../../../_images/create.gif ../../../_images/query.gif ../../../_images/edit.gif
 
Show progress bar during tuning.
startTuning (st) bool ../../../_images/create.gif ../../../_images/query.gif ../../../_images/edit.gif
 
An ipr image has been specified and now changes to shading networks should force an image to be produced.
stopTuning (spt) bool ../../../_images/create.gif ../../../_images/query.gif ../../../_images/edit.gif
 
Tuning should cease but ipr image should not be closed.
underPixel (un) int, int ../../../_images/edit.gif
 
Get list of objects under the pixel sprcified.
update (u) bool ../../../_images/create.gif ../../../_images/edit.gif
 
Force an update.
updateDepthOfField (udf) bool ../../../_images/create.gif ../../../_images/edit.gif
 
Force a refresh of depth-of-field.
updateLightGlow (ulg) bool ../../../_images/create.gif ../../../_images/query.gif ../../../_images/edit.gif
 
Automatically update when light glow changes.
updateMotionBlur (umb) bool ../../../_images/create.gif ../../../_images/query.gif ../../../_images/edit.gif
 
Automatically update when 2.5D motion blur changes.
updatePort (up) unicode ../../../_images/create.gif ../../../_images/query.gif ../../../_images/edit.gif
 
The name of the port that is to be updated when pixel values are recomputed. (not currently supported)
updateShaderGlow (usg) bool ../../../_images/create.gif ../../../_images/query.gif ../../../_images/edit.gif
 
Automatically update when shader glow changes.
updateShading (us) bool ../../../_images/create.gif ../../../_images/query.gif ../../../_images/edit.gif
 
Automatically update shading.
updateShadowMaps (usm) bool ../../../_images/create.gif ../../../_images/edit.gif
 
Force the shadow maps to be generated and an update to occur.
useTemplate (ut) unicode ../../../_images/create.gif
 
Force the command to use a command template other than the current one.

Derived from mel command maya.cmds.iprEngine

Example:

import pymel.core as pm

import maya.cmds as cmds

# Create a iprEngine and tell it about an already created ipr image.
pm.iprEngine(ipr='iprImages/persp_scene1_ipr.iff')

# Tell the iprEngine about the region to update.
pm.iprEngine( 'iprEngine1', e=True, region=(10, 10, 100, 100))

# Tell the iprEngine to watch changes and update pixels.
pm.iprEngine( 'iprEngine1', e=True, startTuning=True )
