Week 11: Graphics

Topics:

• Accessing the pixel array directly, loadPixels(), updatePixels
• Examples of working with pixels, particularly image processing
• PGraphics object and pixel buffers, beginDraw(), endDraw()
• GPU vs. CPU, parallel processing
• Graphics APIs, OpenGL, Processing's render pipeline
• Writing custom fragment and vertex shaders for advanced graphics

Reference:

This week was mostly context and reference material for you to work with as you develop your skills further beyond this class, especially with shaders. I think PGraphics objects might be useful for several of you on your finals, however.

See the following resources for shaders - they go into very necessary detail for understanding this esoteric side of creative programming:

• Processing Shader Guide
• The Book of Shaders
• Gene Kogan Processing shaders
• Shadertoy showcase

Example sketches in https://github.com/whoisbma/Code_2_SP19/tree/master/Week_11 contain the in-class code I wrote with some elaborations. The shader examples contain some additional comments for basic info, but you won't understand all of it unless you dive deep.

Due Next Week:

Submit an iteration sketch of your final to canvas via github as usual.

During one on ones today I suggested everybody make certain progress in their work - in general, by next week you should have a primary feature prototyped in some form, or the overall flow of your application working. Some folks haven't started yet, which is not great. We only have one more week where I can give in-progress feedback in class, so make the most of this next week.
