ios - Fragment Shader GLSL for texture, color and texture/color -
ios - Fragment Shader GLSL for texture, color and texture/color - i want accomplish glsl shader, can texture , color vertex objects. in fact, works me in 2 3 cases: 1) if have texture assigned (but no specific color - color "white"), textured object - works 2) if have texture , color assigned, textured object modulated color - works 3) if have color assigned no texture, black object - doesn't work my shader looks this: varying lowp vec4 colorvarying; varying mediump vec2 texcoordvarying; uniform sampler2d texture; void main(){ gl_fragcolor = texture2d(texture, texcoordvarying) * colorvarying; } i guess that, texture2d(...,...) returns 0 if no texture assigned - seems problem. there way in glsl can check, if no texture assigned (in case, want gl_fragcolor = colorvarying;) "if" isn't alternative in glsl shader, if understanded correctly - ideas accomplish this? or necessary create 2 different shaders both cases? like i'd ...
