We will implement navier-stokes equations for incompressible fluid flow, using compute shaders.
The basic sim concepts will be developed in the studio and you will implement these parts individually :
Mouse input
- take the mouse input pixel position
Input.mousePositionand add velocity / concentration to the fluid field
Boundary conditions
- Velocity Condition : before Advection kernel, set border velocities to be the negative of the inner neighbor (see slide 29)
- Pressure Condition : before ProjectField kernel, set border pressures to be the same as inner neighbors (see slide 30)
Add an obstacle into the field - set velocity field to 0 for some shape inside the field.
Code Organization
- We'll go over how to make helper functions to dispatch the kernels and set up textures, to avoid duplicated code.
Due midnight November 21.
- 40 points for working fluid sim
- 15 points for mouse input
- 15 points for boundary conditions
- 20 points for numerical stability - does the sim not explode for all parameter values?
- 10 points for code organizaiton and comments (make helper functions to dispatch kernels)
(this is also in the syllabus, but consider this an updated version)
-
Disregard what the Syllabus said about Moodle, just submit your work to a branch on github on this repo (branch should be your firstname-lastname) When you are finished, "Tag" the commit in git as "Complete". You can still work on it after that if you want, I will just grade the latest commit.
-
The project has to run and all the shaders you are using should compile. If it doesn't I'm not going to try to fix it to grade it, I will just let you know that your project is busted and you have to resubmit. Every time this happens I'll take off 5%. You have 24 hours from when I return it to get it back in, working.
-
Late projects will lose 10% every 24 hours they are late, after 72 hours the work gets an F.
-
Obviously plagarism will not be tolerated, there are a small number of students so I can read all your code. Because it is on git it's obvious if you copied some else's. If you copy code without citing the source in a comment, this will be considered plagarism.
