![]() Some optimizations here would be to use quad billboarding instead of cubes for couple million more on screen and omitting the Geometry shader entirely as these first start as GL_POINTS then are constructed into 24 vertices as the output. Flow chart of main program that renders water waves after we have texture. The Fountain Simulation Before you start. ![]() 2.1 OpenGL Command Syntax As you might have observed from the simple program in the previous section, OpenGL commands use the prefix and initial capital letters for each word making up the command name (recall glClearColor, for example). ![]() When the particles fall below a threshold value from gravity, its position resets back to its initial starting point along with its starting velocity and repeats the process to continue the flow. 3D graphics programming is generally done using libraries such as OpenGL. FLOWING FOUNTAIN 2015 5 Dept of CSE, CIT, Gubbi. The different blue shades were randomized using an HSL wrapper and the background is a 2k image texture cubemap. There are downsides to using SSBO's as they may be slower to access than Uniform buffer objects, and take up more vram as you can see when the program is running. The collision, velocity, gravity, damping, friction, and position updates are done in the Compute shader using a shader storage buffer object as a storage block to hold 2 million particles. This is an example of using 2 million cube particles in different shades of blue to simulate a water fountain using OpenGL 4.5.0 C++.
