I use AddFragmentShaderReplacement for fragment shader added “uniform sampler2D s”, Can someone tell me how to bind a texture to “sampler2D s” in VTK?

See TestMultiTexturing.cxx for an example. To bind the texture use

actor-\>GetProperty()-\>SetTexture(“skyclouds”, tex2);

that will cause the texture to be bound/activated and then unbound/deactivated when that actor is rendered.
