Day 40 The Dawn of Age

I went to test out the different system. It was amazing as bizarre but some nice result was achieved. I tried various ways of doing like duplicating the system, adjusting its position to see if the placement of system will affect the field. Also alter the direction of the normal to change its direction of flow.

 
test 1 -- 42 Mins

test 2 -- 15 Mins

Some of the test was bizarre but I find it interesting on the advection.

Day 39 The Dawn of Age

Couldn't really get the result I wanted, I was abit stuck with the current system where i had no idea how to imply/activate the field to affect the particles With understanding of using sopgeo to bring in the field and gasparticletofield, I roughly work my way out and re-create the hip file sent by the odforce user. However, Mr Ron gave me a file he did, some test of various method of different system. He show me on how he did it in full detail and different segment to take note of.

Above are the different types of system.

Day 38 The Dawn of Age

After Mr Douglas saw our weekly progress, he show us some software related stuff. With my vector field ready, I could art direct the way of the water gush. I went on to the forums to ask for directions regarding the series of Gas node which can "activate" the vector field to progress on. Soon enough, Macha from Odforce came out with a reply with a hip file attach. The hip file is a test where smoke goes through two spinning circle which is the main field. A SOPgeo and a GasParticletoField node were included in the autoDopnetwork. The SOPgeo is to bring in the two spinning circle as a geometry to act as fields and GasParticletoField to advect the movement of the flow.

Day 37 The Dawn of Age

After getting two curve field going in opposite position, I did not know how to continue. Mr Ron then show me the direction by letting me to research on a few node which will be the gasadvert field, field force and the the gasfield vop. All this might help to activate the field to affect the water.

I went to test out white caps on my sculpted fluid but somehow I keep getting error when I hit the whitecaps tool on the shelf. Some forum user also encounter such error when using white caps.

Day 36 The Dawn of Age

I went to Odforce to search for topic using keywords like water, ocean, flood, fluid and etc. Certain topic have links to their personal test in Vimeo, links to another topic, and many variation. I checked out their videos and ask them to teach me how to do their stuff step by step or if possible, to share the hip file. Hoping to get their hip file, "hack" into it and study, then add to my knowledge. Later into the day, Mr Ron dropped by and help us with our progress. I told him that I am stuck with the previous system where the particles driven by the metaball attractor. Mr Ron then showed me an interesting and better (in my option) way. It is by driving the water stream into a velocity field and use that velocity field to affect the movement.

Using a line to create a curve with expression like sin and cos functions. With resample node to alter the points and attribute-create to "force" out the normals. Downloaded a OTL from sidefx.com, Tangent node. Another OTL will be the volume attribute transfer.

Day 35 The Dawn of Age

I went to watch some tutorial video. And I encounter a tutorial which might help with my attachment in sidefx. Its similar to how sandman was form in Spiderman 3. It is from many particles to form into a organic being. I saw/found a video on Vimeo.

I also did a simple testing about blend-shape



I also stumble upon a video and talks about white caps which I wanted to try out on my fluid test.

Day 34 The Dawn of Age

Mr Douglas came over to see our progress. I showed him the metaball attractor system where this could be the system to simulate the curling of the water stream. However I explain to him that when I tried to do this using a POPsolver in a flip fluid emitter, it does not work and will try different alternative, Mr Ron explained. After Mr Douglas finished going through everyone work, I went to the forums to see if theres reply. There was reply from both forums, which is good. A user from CGtalk suggest an interact pop to ease the clumps. A couple of users in Odforce suggest doing a oversample using expression like $FF.
