So here is a previous question: How to implement a ShaderToy shader in three.js
Tried to implement the steps from the link above into this code unsucessfully: three.js/blob/master/examples/webgl_shader.html
So I replaced the original vertex shader and the origianl fragment shader so I got this code:
<script id="vertexShader" type="x-shader/x-vertex"> varying vec2 vUv; void main() { vUv = uv; vec4 mvPosition = modelViewMatrix * vec4(position, 1.0 ); gl_Position = projectionMatrix * mvPosition; } </script> <script id="fragmentShader" type="x-shader/x-fragment"> uniform float iGlobalTime; uniform sampler2D iChannel0; uniform sampler2D iChannel1; varying vec2 vUv; void main(void) { vec2 p = -1.0 + 2.0 *vUv; vec2 q = p - vec2(0.5, 0.5); q.x += sin(iGlobalTime* 0.6) * 0.2; q.y += cos(iGlobalTime* 0.4) * 0.3; float len = length(q); float a = atan(q.y, q.x) + iGlobalTime * 0.3; float b = atan(q.y, q.x) + iGlobalTime * 0.3; float r1 = 0.3 / len + iGlobalTime * 0.5; float r2 = 0.2 / len + iGlobalTime * 0.5; float m = (1.0 + sin(iGlobalTime * 0.5)) / 2.0; vec4 tex1 = texture2D(iChannel0, vec2(a + 0.1 / len, r1 )); vec4 tex2 = texture2D(iChannel1, vec2(b + 0.1 / len, r2 )); vec3 col = vec3(mix(tex1, tex2, m)); gl_FragColor = vec4(col * len * 1.5, 1.0); } </script> This is clear but how and Where to implement the tuniform:
var tuniform = { iGlobalTime: { type: 'f', value: 0.1 }, iChannel0: { type: 't', value: THREE.ImageUtils.loadTexture( 'textures/tex07.jpg') }, iChannel1: { type: 't', value: THREE.ImageUtils.loadTexture( 'textures/infi.jpg' ) }, }; and the iGlobalTime parts?
tuniform.iChannel0.value.wrapS = tuniform.iChannel0.value.wrapT = THREE.RepeatWrapping; tuniform.iChannel1.value.wrapS = tuniform.iChannel1.value.wrapT = THREE.RepeatWrapping; So my question is: how to modify this code (or any thrre.js code): three.js/blob/master/examples/webgl_shader.html
to display a working shadertoy example which includes iGlobalTime as well?
