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). 

This is a viewport flipbook, not rendered

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

This video shows how I export and import models and animation to the Alembic format (.abc). It also shows how imported Alembic files can have some flexibility in terms of offsetting animation timings, playback speed and cycling options .

Setting Maya Viewport's Texture Resolution Above 256x256

While working on a project that required me to display map features in very fine detail, I ran into the problem of Maya's limited ability to show texture maps at higher than 256x256 in the viewport. On the left is the source image supplied as a texture on the plane in the Maya scene, displayed from Window's image viewer. On the right inside of Maya is the same map that's loaded as a lower resolution map. In the hardware texturing setting for that shader (I'm using a surface shader), we soon find out that 256x256 is the highest resolution we can choose to show our texture at. Searching through the Internet I had the good fortune to come across this very useful tip on a blog that solved the problem for my situation: http://blog.erlendsakshaug.com/post/59585323349/maya-tip-set-texture-resolution-above-256x256-in-the To find out the current hardware texture resolution for the shader of this object, we have to find out the name of the shader. For me it is ...

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...
