Link Parameters

Using external parameters, animations can be set up.

There are currently 7 types of parameters available for animations:

• Sliders
• Angles
• Points
• 3D Points
• Checkboxes
• Colors
• Layers

And each group of parameters has 10 controllers for manipulation.

Example:

void main(){
    outColor = vec4(uv, slider[0], 1.0);
}

For instance, changing slider 0 will alter the color in the preview window.

Details

In PixelsWorld, parameters are declared as follows:

uniform float slider[10];
uniform float angle[10];
uniform bool checkbox[10];
uniform vec2 point[10];
uniform vec3 point3d[10];
uniform vec4 color[10];
uniform sampler2D layer[10];
uniform sampler2D inLayer;

Note

• "inLayer" represents the input layer.
• sampler2D is a variable type provided by GLSL; you don't need to understand this type. If you want to know about layer parameters, please refer to "getColor".
• "uniform" denotes a global variable.
