  1. https://en.wikipedia.org/wiki/Robinson_projection

    The projection is defined by the table:

    Latitude PLEN PDFE
    00 1.0000 0.0000
    05 0.9986 0.0620
    10 0.9954 0.1240
    15 0.9900 0.1860
    20 0.9822 0.2480
    25 0.9730 0.3100
    30 0.9600 0.3720
    35 0.9427 0.4340
    40 0.9216 0.4958
    45 0.8962 0.5571
    50 0.8679 0.6176
    55 0.8350 0.6769
    60 0.7986 0.7346
    65 0.7597 0.7903
    70 0.7186 0.8435
    75 0.6732 0.8936
    80 0.6213 0.9394
    85 0.5722 0.9761
    90 0.5322 1.0000

    The table is indexed by latitude at 5 degree intervals; intermediate values are calculated using interpolation. Robinson did not specify any particular interpolation method, but it is reported that he used Aitken interpolation himself. The PLEN column is the length of the parallel of latitude, and the PDFE column is multiplied by 0.5072 to obtain the distance of that parallel from the equator. Meridians of longitude are equally spaced on each parallel of latitude.
     


  2. Hi Guys,

    I'm very new to houdini and I've been trying to learn fluid sim lately. From few days I've been trying a tornado system from tutorial from 3dbuzz and a technical paper (http://repository.tamu.edu/bitstream/handle/1969.1/ETD-TAMU-2011-05-9417/DWIVEDI-THESIS.pdf?sequence=2).

    I've completed the particle system part but the fluid sim is out of my league for now. I'd be very grateful for any tips to convert that to fluid sim. I want to use this opportunity to start learning about fluids. Thank you.. :)

    I've also attached the final file I came up with. I tried the fluid sim from the thesis and other post on the forum but failed :"> hehe.. thank you..
