setMatrix4d

public void setMatrix4d(com.jogamp.opengl.GL3 gl,
 String name,
 javax.vecmath.Matrix4d value)

Set a matrix in the shader. Java uses column-major order, where OpenGL and DirectX use row-major order. Thus the thurd parameter is true to make the video card transpose the matrix from row-major to column-major.

Parameters:

gl - the viewport context

name - the name of the uniform variable

value - the matrix to set
