Description:
Fragments is a demo application for a custom OpenGL Java implementation for Android.
The demo trails your finger with vibrant, randomly generated planes as you drag your finger across the screen.
Implementation:
The planes are drawn on an Android bitmap using a custom written Java implementation of OpenGL (called SGL) for Stanford's CS148 Graphics class.
Before each addition to the canvas, a random rotation and scaling matrix is pushed onto the SGL stack. Each plane is a square drawn with OpenGL calls to a "triangle strip." After a plane has been drawn, the SGL state is restored from the random transformations so that a plane with new properties can be drawn.
The coloring of the squares is calculated using barycentric interpolation between assigned colors to the triangle strip vertices.
The OpenGL/SGL implementation that this demo showcases features a matrix stack, vertice position and color specification, triangle drawing, and barycentric interpolation, among other features to provide a useable portion of the features in the full OpenGL API.
Performance:
IMPORTANT: Please note that this demo application is PROCESSOR INTENSIVE. It is meant to showcase the possibility of a custom, scratch-built Java implementation of OpenGL/SGL on the Android platform. Since it is written in Java and does not utilize the Java NDK or make GPU calls, this application may have a rendering delay and run SLOWER on devices with weak CPUs.
Feedback:
This application is still under development. Any questions or comments are appreciated!
