Procedural Generation and Simulation
Prof. Dr. Lena Gieseke | l.gieseke@filmuniversitaet.de
Session 02
This session is due on Wednesday, April 30th before class.
This assignment should take <= 4h. As this assignment is open-ended, it is up to you to manage your time.
Function Designs
Task 02.01 - Inspiration
Go to the shadertoy site and browse the examples a bit. Submit the link to at least one example you like (you don’t have to understand the code). Think about what you like about the example and why. You don’t have to write anything about that in your submission but be able to explain it in class.
On a side note: shadertoy code does not directly run within the glsl-canvas environment (see Task 2.2).
Submission: Links in your markdown submission file..
Task 02.02 - Brick Pattern
Understand the given brick pattern code in the brick.frag file and insert comments explaining for each code line of the brick pattern what it does.
One cell of the brick pattern is parameterized as follows:
Note: For running the code, install the Visual Studio Code extension glsl-canvas. With this plugin, you can display a .frag fragment shader file directly in VSCode. For rendering, select from VSCode’s Command Palette the command Show glslCanvas.
Submission: Submit commented copy of the code as brick_lastname.frag in your assignments folder.
Task 02.03 - Pattern Experiments
Create a digital 2D pattern of your liking, e.g. the one you designed for the last homework by hand (Task 01.03 ) but this is entirely up to you.
With this task, I want you to practice understanding and building individual function designs. You are free to choose any design and environment you want, as long as it includes the building of a somewhat complex function, which has a visual outcome. Choose the scenario you are interested in and/or helps you in your learning. Your options are:
- GLSL fragment shader
- See the GLSL examples
- Unreal Material Node Network
- See the Unreal scene ->
M_pattern_circles_nodes
- See the Unreal scene ->
- Unreal Material Custom Node + HLSL
- See the Unreal scene ->
M_pattern_circles_hlsl
- See the Unreal scene ->
Submission: At least one image of your resulting pattern (an Unreal screenshot is still fine), linked in your .md submission file. If you started with given code or a give setup, briefly explain your changes.
Learnings
Task 02.04
Summarize your learnings (text or bullet points - whatever you prefer but you must use whole sentences). What was challenging for you in this session? How did you challenge yourself?
Submission: Answer in your markdown submission file.
Answer all questions directly in a copy of this file and also link and display all of your images in that file. Submit your copy as pgs_XX_lastname.md in your submissions folder (replace the XX with the number of the session).
Happy Functioning!
