PShader

Sets the uniform variables inside the shader to modify the effect while the program is running.

• .set(name, x)
• .set(name, x, y)
• .set(name, x, y, z)
• .set(name, x, y, z, w)
• .set(name, vec)
• .set(name, vec, ncoords)
• .set(name, boolvec, ncoords)
• .set(name, mat)
• .set(name, mat, use3x3)
• .set(name, tex)

• name(String)the name of the uniform variable to modify
• x(int, float, boolean)first component of the variable to modify
• y(int, float, boolean)second component of the variable to modify. The variable has to be declared with an array/vector type in the shader (i.e.: int[2], vec2)
• z(int, float, boolean)third component of the variable to modify. The variable has to be declared with an array/vector type in the shader (i.e.: int[3], vec3)
• w(int, float, boolean)fourth component of the variable to modify. The variable has to be declared with an array/vector type in the shader (i.e.: int[4], vec4)
• vec(PVector, int[], float[], boolean[])modifies all the components of an array/vector uniform variable. PVector can only be used if the type of the variable is vec3.
• ncoords(int)number of coordinates per element, max 4
• mat(PMatrix2D, PMatrix3D)matrix of values
• use3x3(boolean)enforces the matrix is 3 x 3
• tex(PImage)sets the sampler uniform variable to read from this image texture

• void
