## Approach
1. Advect particles or points (Garbage in garbage out; interesting source interesting output)
2. Convert to **VDB** (stores values where there is one hence faster and cost-effective)
3. Add `DOP` > Add `smokeobject` + `pyrosolver`
4. Add disturbance or details with microsolvers (Gas `dissipate`, `disturbance`, `turbulence`)
5. Optimize simulation calculation with`gasresizefluiddynamic`
6. Caching simulation
7. Texturing & Rendering
## **Syllabus**
* **Kinesthetic learning**
* Do R\&D on different settings and render them out
##
## Shadow not showing in viewport (not solved)
* Viewport preferences > Under the Effects tab make sure HDR rendering is enabled.
* Under the Geometry tab of the Display dialog there is also a Volume Quality drop down.
* Smoke density in smoke
## From Applied Houdini volumes II
### Good practice
* **Division sizes:** 150 (sketch), 300 (detailed), 600 (HQ)
* Use Takes to easily toggle values
* Use size of container/division size to get the optimal value for voxel size
* Use **OpenCL** to speed up rendering if you have a good graphics
* Override divisions to about 50 for visualizing guides
### Notes
* Temperature is creating velocity
* Visualize velocity
* Gas resize fluid dynamic - have a threshold to cut down on size of bounding box
* Tracking object - use original
* MICROSOLVER
* gasdissipate
* gasdisturb
* Take edges and perturb them
* prevents mushroom smokes when you disturb the vel
* control settings - vel
* Rest field
* PRESSURE
## Applied Houdini Dynamics III
* **Alternate cloud volume**
* `cloud`
* `cloudnoise`
