只需劃分一個PNG圖像的信道來表示具有不與每個other.Below共混紋理潑灑是表達什麼我試圖實現爲簡單代碼的示例:webgl的着色器 - 分通道RGBA
uniform sampler2D my-alpha-png;
uniform sampler2D texture1;
uniform sampler2D texture2;
uniform sampler2D texture3;
vec4 alpha = texture2D(my-alpha-png, vUV).rgba;
vec4 tex0 = texture2D(texture1, vUV *10.0).rgba;
vec4 tex1 = texture2D(texture2, vUV *10.0).rgba;
vec4 tex2 = texture2D(texture3, vUV *10.0).rgba;
vec4 colornone = alpha.a; // i want this channel to be blank;
vec4 color1 = alpha.r; // this is texture1
vec4 color2 = alpha.g; // this is texture2
vec4 color3 = alpha.b; // this is texture3
gl_FragColor = // ????
我已經嘗試了許多變化我只能設法讓兩個紋理沃金,但阿爾法總是以及下方的紋理圖像阿爾法PNG:
我更感興趣的是分裂渠道代表在輸出上,只需要四個通道r,g,b,一個不需要計算黑白...
謝謝。
