Im trying to understand how to implement multiple buffers in three.js by porting a shader from shadertoy with help of this thread. https://discourse.threejs.org/t/help-porting-shadertoy-to-threejs/

I tried to rewrite it for js but it doesnt compile. Here is the code: https://codepen.io/haangglide/pen/BaKXmLX

It is based on this one: https://www.shadertoy.com/view/4sG3WV

My understanding of using buffers is:

1. create a bufferscene

bufferAscene = new THREE.Scene();

1. create a texture

After upgrading the Selenium NuGet packages in our solution to version 3.141.0 (both Selenium.WebDriver and Selenium.Support), the IHasInputDevices interface now has a warning:

'IHasInputDevices' is obsolete. 'Use the Actions or ActionsBuilder class to simulate mouse and keyboard input.'

I created a utility class called LazyWebDriver, which implements the IWebDriver, IHasInputDevices and IActionExecutor interfaces. The LazyWebDriver class delays the instantiation of ChromeDriver until a member of IWebDriver gets accessed. This allows us to pass an IWebDriver object around and delay the appearance of the browser window, in case a test fails during the setup phase.

Code for the LazyWebDriver class:

I am trying to fade between several different types of shaders from shadertoy by importing them to p5.js and am trying to figure out the best way to do that? I am trying to figure out if I can somehow just use the tint() function to adjust the opacity of the shader after I load them in and loop through them, but don't exactly know if that's possible. Here's what I have so far, any help would be greatly appreciated.

I'm looking for a way to switch between multiple shaders that are shaders from shadertoy.com I have been using these instructions on how to port shadertoys with p5.js and have been successful with using sublime with it or a website called glitch.com

My question is, how can I loop through displaying one shader to the next shader? Here is the javascript file that I have so far. I know I'll need to make a loop with the function draw and call on the two different shaders I preloaded, but am having some trouble with syntax since I am very new to coding. Any help would be appreciated!

I came across this implementation of Lattice Boltzmann fluid solver from this blog which goes over its implementation. I decided I wanted to translate this to ShaderToy with webgl. Instead of computing each step necessary for equilibrium, the limitations of shader toy force me to use multiple texture frames.

My algorithm is basically like this:

• Calculate bulk velocity and density for each cell in texture A from textures B, C, and D which hold the 9 direction components (NW,N,NE,W in each vec4 in B, E,SW,S,SE in each vec4 in C, center in each vec4 in D).

• After these components are calculated, recalculate stream/advection for each necessary cell for each texture frame, B,C,D, and take the density and velocity components from A to compute the equilibrium.

• set the final values for each direction to new_direction - (new_direction - new_direction_equilibrium), ie(north_west - (north_west - north_west_eq))`. This isn't any different from the reference code.

Additionally I wrap coordinates around, so there are no boundary conditions in order to avoid dealing with boundary logic, and the user clicks to cause disturbances in the lattice, which sets the "not moving" direction value to a number.

In my code however, I end up getting lots of NaNs (colored here in white, red represents the density) and I'm not sure why. I put safe guards in locations in my code to avoid zero densities causing issues, but that didn't seem to do anything.

You can test this out on shadertoy, but my code is as follows:

I've been trying to port a shader from ShaderToy to regular WebGL, and hit a bit of a wall. I managed to make multipass shaders work, but not the ones that has themselves as an input channel. I made a test example here:https://www.shadertoy.com/view/WsfSzj. The shader has two passes, which both have Buffer A as input. As I understand it when a buffer has itself as an input it uses the output from itself from the previous timestep.

So what I tried was making two rendertargets with the structure:

I am having trouble porting some code I have successfully implemented in Shadertoy to desktop OpenGL, the problem is that I need to create a FrameBufferObject FBO so that I can do offscreen computations that will be later passed on to the main glsl fragment shader, the thing is that this buffer needs to reference itself as a texture to get the previous values for it to be able to run a simulation.

I have successfully created the FBO:

I'm just getting started with shaders and am having trouble drawing a circle based on the cursor position without it appearing as an ellipses.

I'm using the following fragment shader (via Shadertoy):

C#, FierFox, Selenium v3.8 My purpose is movement cursor emulation in browser, using IMouse.MouseMove. Google searching gives me something like that, but I always receive System.NullReferenceException.How I should to use IMouse interface?
