Thanks a lot for this perfect video... I've just took a course on GLSL programing and decided to start learnin TD with the promise that it would be easy to port them. You made it so simple and easy! Thanks!

Thanks a lot, this really helps!

Hi, so in case the buffer is asking iChannelResolution[4] says please ad to array page but now it wants a chop, sorry for asking but I have in front of me the wiki about array but to be frank it might just as well be written in japanese. There is not even an actual picture of touchdesigner array page. Imagine you had to explain to someone what is a photograph without even showing one, that is to resume the way they explain things on wiki touch designer, I'm sure an experienced coder would make sense of these instructions but for normal mortals its impossible and very frustrating. It's only when I found your instructions I managed to convert few shaders with buffers, so thx a lot for that. This tutorial made it crystal clear!

cool this helps!

Hi, Great tutorial. Thank you ! Just wondering, I've tried a different shader and got a lot of errors I couldn't solve since I didn't knew how to manage them on TouchDesigner (like vEnv and vEnvColor) Any suggestion how can I improve my knowledge to better understand this? Also, would like to better understand formulas in touchdesigner. Any reference you would like to share? Thank you again!

how would you go about shaders that have more buffers?

Thanks for your great tut! but I got a question about the second part! how can we use mouse in touch just like the source website? I used mouse-in Chop and hooked it up to iMouse parm in GLSL node but did not work! any ideas?

In my case of Shader i have this errors: 0(116) : error C7011: implicit cast from "vec3" to "vec2" 0(245) : error C7011: implicit cast from "vec4" to "vec3" and this lines are: vec3 vEnv = texture(sTD2DInputs[0], vEnvDir).rgb; fragColor = vec4(vResult,0.1); What is the error?

i have error like this. ERROR: /project1/glsl3_pixel:13: '' : syntax error, unexpected BUFFER, expecting COMMA or SEMICOLON this my full Image Script: layout (location = 0) out vec4 fragColor; uniform vec3 iResolution; const vec3 CellColor = vec3(0.2, 0.2, 0.2); const vec3 RingColor = vec3(0.0, 0.2, 0.2); const vec3 DiskColor = vec3(0.0, 0.0, 0.0); void main() { vec2 uv = gl_FragCoord.xy / iResolution.xy; vec4 buffer = texture(sTD2DInputs[0], uv); vec3 color = 1.0*(buffer.x * CellColor + buffer.y * RingColor + buffer.z * DiskColor); float c = 1.0 - buffer.z; float c2 = 1. - texture(sTD2DInputs[0], uv + .5/iResolution.xy).y; color += vec3(.6, .85, 1.)*max(c2*c2 - c*c, 0.)*4.; fragColor = vec4(color, 1.0); } ///////////////////////////////////// Error on this line: vec4 buffer = texture(sTD2DInputs[0], uv); i do same with your video why like tis?
