Houdini Pyro Colour Advection

-

I've always wanted to do this! Advecting swirling colours in Houdini used to require quite a bit of preparation constructing the volumes, but not any more with the volumeRasterizeAttributes that can create volumes from mixed data types (float, vec3, etc).

For some reason, I find myself watching the yellows and greens every time.

Maya UI Layout Example

-

In reply to another StackOverflow question , I wrote 2 blocks of code that shows 2 UI layouts created with Maya's UI framework. First one looks like this: This is the code that created this first one. import maya . cmds as mc def buildUI (): winName = 'myWindow' winWidth = 200 # set a target width and reference this when you specify width if mc . window ( winName , exists = True ): mc . deleteUI ( winName ) mc . window ( winName , width = winWidth , title = 'Test Window' ) # i always have keep a reference to the main columnLayout mainCL = mc . columnLayout () mc . text ( label = 'text row 1' ) # tmpRowWidth controls the width of my columns in the rowLayout # with reference to winWidth tmpRowWidth = [ winWidth * 0.3 , winWidth * 0.7 ] mc . rowLayout ( numberOfColumns = 2 , columnWidth2 = tmpRowWidth ) # at this point our UI pointer is under the rowLayout mc . text ( label = 'row colu...

Maya Expressions Part 02 - Conditional Statements

In this second video of my Maya Expressions series, I show how use the graph editor to display a visual representation of the value of our expressions with a graph. Then I move on to explain the basics of conditional statements in Maya's expression language, which also works with MEL scripts. A basic conditional statement in MEL and Maya expression language has the structure as such: if (condition) {     statement1;     statement2; } Condition is a test to see if a comparison between values is true, or false, for most cases. Example 1: if (cube1.translateX > cube2.translateX) { do_something; } In the above example, if cube1's translateX value is greater than cube2's translateX value, then do_something will be performed. Example 2: if (cube1.translateX == cube2.translateX) { do_something; } In the above, we are testing for equality. if both the values are equal, the do_something will be executed. Example 3: if (cube1.scaleX >= cube2.scal...

Finding the Centre Position of a Polygon Face: Maya Python API

-
In the past few days I found myself having to find the position of face centres of a polygon. Looking through the Maya documentations I find no MEL or Python commands that can do this. So I had to do a Google search the answer. The most useful solution I found was from a discussion in Google Groups, in a reply by Justin Israel (who works in Weta Digital according to his Google+ profile ): https://groups.google.com/d/msg/python_inside_maya/UoMVxr0deVo/OJ2K8IpevxQJ Here is an excerpt of Justin's answer: import pymel.core as pm import maya.OpenMaya as OpenMaya face = pm.MeshFace("pCube1.f[64]") pt = face.__apimfn__().center( OpenMaya.MSpace.kWorld) centerPoint = pm.datatypes.Point(pt) Here is another interesting article discussing how we can go about finding the centre position of a face:  http://mayastation.typepad.com/maya-station/2009/11/where-is-the-center-of-a-polygon.html
