iiinova — where your digital self keeps evolving

Excellent visualization! This is basis of the technique I called "turbulence" which I use in my tiny shaders for fluids, smoke and fire. It's cheap and deterministic

Less than 4 weeks left to write the best article for FragCoord. It could be a tutorial, breakdown, devlog, showcase anything graphics related. I'll be giving the best ones a FragCoord Pro for a year (which unlocks 3D buffers, compute shaders, MRT and more)

Thank you for 150 followers on FragCoord! I've put 1000+ shaders on there, with many more to come.

I've also create an event for the best written article. If you want to write about graphics optimization, procedural generation, mathematics or anything else, you may win a year of FragCoord Pro for free! I'm looking to make FC the best place for professionals

I took it one step further. You can also put expressions into the plot! Expressions like: "l * 7." or "sin(z) + 1." Lots of complex expressions are possible

100

You can plot 2 variables simultaneously for 2D graph, visualized with a heatmap! Each variable may have it's own defined range, which is automatically detected, but can be manually adjusted

100

I wanted the interface to be dead simple, but also versatile enough to handle multiple variables. The first gets plotted on the "x" and additional variables get adjustable sliders. You can simply drag any variable into the x to plot against the x-axis

100

My favorite is definitely the graph. I needed a way to visualize my falloff function and realized there was no way to do that in FC yet. You can select an expression, lock it and compare with other expressions

I've added a 1-month free trial which let's you try extra features like compute shaders, 3D buffers, cubemap buffers, MRT and more. Paid users get $20/mo credits which can go towards commercial shader licenses
