I wondered how this can be modified to accept multiple input points, I can't get it to work.

Hey great tutorial, also great seeing someone use more complex things like the glsl material. It would be very cool though if at the beginning you'd briefly explain what exactly you are trying to do, ie. say I think this effect can be done by applying a color gradient to a moving grid or smth like that. That would make the tutorial easier to follow bc now it took me quite some time to exactly understand what you are trying to do. Anyways keep up the great work

I dont understand, at 8 minutes i have copy paste what u have written, and save the file. and copy the path, my computer dont find it. and by the way, it also don t put everything incolor or display like on ur screen

Stil having troubles at the end, when dragging advectVelocity nullTop onto feedback before velocityGLSL. when doing is i end up having the simulation but it's so pixelated and not looking correct :(

Brilliant and succinct. thank you so much!

I had to redo it from scratch a second time. I have no idea what the mistake was the first time but I ended up getting a very intense noise in one of the feedback nodes. Finally got it working and can't thank you enough! Awesome tutorial

The glsl compile error 1-CPU cook time not measure on previous cook 2- (7 line pixel shader)- error: project1/glsl1_pixel11: color undeclared identifier Thank You! If you can help me!

u're the one!!

looks amazing going to try it good wrok

is it necessary to make triangles? why not just make quads?

great tutorial and great for building off of thank you!

Hello everyone, would it be possible to add a second point of interaction?

im trying to connect this to Kinect and I am struggglinggggggg

Great tutorial! Learned quite a bit even though it moved a little fast for me. Would have been extra special if the sample file was included.

Very well made, logical structured overview. Mny THX.

amazing tutorial. question here, how do you address "banding" in the gradient when changing this content to higher resolutions?

Thank you so much for sharing! This one was a though ride for me, but you did a great job - appreciated!

my sequence patch for the clear pressure is not showing, the feedback and the null pressure don't show the moving circle, this is the only thing missing, don't know where the error is, could you help me???? thank you! Edit: I did it!!!!!!!! I discover the errors and was able to complete the full tutorial, i spend the last 12 hours eating ice cream and figuring out this until I finally resolved it. Now I will learn how to use a kinect to be able to control it with my hand!

Following this tutorial I've got stuck on the first curlGLSL it appears an error, "the glsl shader has compile errors" i tripled check the code and it appears everything is correct, it shows red and black squares with the warning. I don't know how to move from there, please help. Thank you.

Amazing video! Would you be able to share the toe file for this project?

Very well structured and straight forward tutorial.... You're a great teacher. Thanks for sharing with the community 🙏

wow, so cool.... your teaching is very clear and straight forward... big compliment and many thanks.. I just have a problem left with the resolution. The animation is pixelated, so I don't see the details. Guess, I have to go through it again to see, where the problem is...

Thank you, this is such a nice scene : )

Hey! On both the color and the velocity GLSLs I get the error "'vuV' . undeclared identifier" and 1 compilation error, but I'm pretty sure there are none. However, the color GLSL works fine while the velocity one doesn't.

Hey :) Thanks for this great tutorial! I'd love to finish it but got some trouble at 11:38 I wrote the code uniform sampler2D sColor; inc vec2 vUV; out vec4 fragColor; void main() { TDCheckDiscard(); vec4 color = vec4(1.0); color = texture(sColor, vUV); TDAlphaTest(color.a); fragColor = TDOutputSwizzle(color); } But nothing happen on the colors...Not more visuals and the GLSL1 chop it's now a cylinder red and blue. I use the touchDesigner 2022.33600 could be because of the version of the soft ? Many thanks for any help! cheers

Thank you!

My Wire frame OpenGL Tesselated Wire Frame is not appearing as an option. Any ideas why?

on the expression for scale doesn't work, this is the error: "float() argument be a string or a number, not 'NoneType'". some idea?? :( thanks

I have a question: i was able to make it to 3:47, but on the screen i don't see the grid like in the video, i see a blue and red grid. What do you think is wrong?

Hi ! How I could conect this system to be kinect controlled?

howd you get it in such High quality. Im looking for all of them in HD

Hey! So this worked for me, I'd like to project this and make it receptive to click and drag and not hover. How do I go about it?

hey! fantastic tut! do you know a method to point to the center of the geo with my camera? I want to use your tech in a setup ultrawide for 3 projectors and I need the cam point to the center of the geo (e.g. when you home the camera, but constantly), lookAt doesn't work cause it doesn't recognize the center of the curl instanced noise. I need to point to the moving center of it, any suggestions? thank you!

that is insane bro

Oh, a Mouse in CHOP. cool. (Sad macOS noises)

Thank you! This seems amazingly useful, but I'm still struggling with how I can now create 2D TOP textures to apply to the UV map and make. a seamless texture on the sphere. Any tips?

hi, i just did till first part of the coding but i cant find the red mouse point, need help someone

Thanks Elon

Fantastic! Connecting the replicants to comp tip is awesome.

Thanks for sharing!

Thank you so much. What a great tutorial it is.

All good until I add Uniform float Utime; and add + Utime to the curlnoise and then everything stops. Sublime text is highlighting the return values. Really hope someone can help. I know this is a couple of years old. I haven't got a clue how to fix this.

First expression for scale doesnt work. Gone though the tutorial twice and double check the expression at least 10 times. On version 32050. Anyone else had problems?

what i want to make is an audio-responsive gradient.. do u think this is possible?

so awesome to have this accessible and to be able to learn GLSL from this..

Excellent tutorial, thanks for sharing. I really appreciated your approach in demonstrating operator types one at a time then integrating a few of them.

for pasting/checking for misspellings: uniform float uTime; uniform float uDelta; uniform float uVelDamping; uniform float uLifeDamping; uniform vec4 uNoiseFactor; layout (local_size_x = 8, local_size_y = 8) in; vec3 snoiseVec3( vec3 x ){ float s = TDSimplexNoise(vec3( x )); float s1 = TDSimplexNoise(vec3( x.y - 19.1 , x.z + 33.4 , x.x + 47.2 )); float s2 = TDSimplexNoise(vec3( x.z + 74.2 , x.x - 124.5 , x.y + 99.4 )); vec3 c = vec3( s , s1 , s2 ); return c; } vec3 curlNoise( vec3 p ){ const float e = .1; vec3 dx = vec3( e , 0.0 , 0.0 ); vec3 dy = vec3( 0.0 , e , 0.0 ); vec3 dz = vec3( 0.0 , 0.0 , e ); vec3 p_x0 = snoiseVec3( p - dx ); vec3 p_x1 = snoiseVec3( p + dx ); vec3 p_y0 = snoiseVec3( p - dy ); vec3 p_y1 = snoiseVec3( p + dy ); vec3 p_z0 = snoiseVec3( p - dz ); vec3 p_z1 = snoiseVec3( p + dz ); float x = p_y1.z - p_y0.z - p_z1.y + p_z0.y; float y = p_z1.x - p_z0.x - p_x1.z + p_x0.z; float z = p_x1.y - p_x0.y - p_y1.x + p_y0.x; const float divisor = 1.0 / ( 2.0 * e ); return normalize( vec3( x , y , z ) * divisor ); } float parabola( float x, float k ) { return pow( 4.0*x*(1.0-x), k ); } void main() { vec4 p = texelFetch(sTD2DInputs[0], ivec2(gl_GlobalInvocationID.xy), 0); vec4 v = texelFetch(sTD2DInputs[1], ivec2(gl_GlobalInvocationID.xy), 0); vec4 i = texelFetch(sTD2DInputs[2], ivec2(gl_GlobalInvocationID.xy), 0); vec3 pos = p.rgb; vec3 vel = v.rgb; vec3 ini = i.rgb; //position float life = p.a; life -= uLifeDamping; if (life <= uLifeDamping) { life = 1.0; pos = ini; } pos += vel; imageStore(mTDComputeOutputs[0], ivec2(gl_GlobalInvocationID.xy), TDOutputSwizzle(vec4(pos, life))); //velocity vec3 noise = uDelta * uNoiseFactor.x * curlNoise(pos * uNoiseFactor.y + uTime * uNoiseFactor.z); vel += noise * uNoiseFactor.w; vel *= uVelDamping; float size = parabola(1.0 - life, 1.0); imageStore(mTDComputeOutputs[1], ivec2(gl_GlobalInvocationID.xy), TDOutputSwizzle(vec4(vel, size))); }

thank you very much!

First tutorial I could understand. Truly a Quick Start Guide.
