Name | ### PShader
Examples |
    PShader blur;

    void setup() {
      size(640, 360, P2D);
      // Shaders files must be in the "data" folder to load correctly
      blur = loadShader("blur.glsl");
      stroke(0, 102, 153);
      rectMode(CENTER);
    }

    void draw() {
      filter(blur);
      rect(mouseX-75, mouseY, 150, 150);
      ellipse(mouseX+75, mouseY, 150, 150);
    }
Description | This class encapsulates a GLSL shader program, including a vertex and a fragment shader. It's compatible with the P2D and P3D renderers, but not with the default renderer. Use the loadShader() function to load your shader code. [Note: It's strongly encouraged to use loadShader() to create a PShader object, rather than calling the PShader constructor manually.]
Methods |
set() | Sets a variable within the shader
Constructor |
    PShader()
    PShader(parent)
    PShader(parent, vertFilename, fragFilename)
    PShader(parent, vertURL, fragURL)
    PShader(parent, vertSource, fragSource)
Parameters |
parent | PApplet: the parent program
vertFilename | String: name of the vertex shader
fragFilename | String: name of the fragment shader
vertURL | URL: network location of the vertex shader
fragURL | URL: network location of the fragment shader
