31 J3DIMatrix4 - A 4x4 Matrix
37 This class implements a 4x4 matrix. It has functions which duplicate the
38 functionality of the OpenGL matrix stack and glut functions. On browsers
44 Constructor(in J3DIMatrix4 matrix), // copy passed matrix into new J3DIMatrix4
46 Constructor() // create new J3DIMatrix4 with identity matrix
49 void load(in J3DIMatrix4 matrix); // copy the values from the passed matrix
50 void load(in sequence<float> array); // copy 16 floats into the matrix
51 sequence<float> getAsArray(); // return the matrix as an array of 16 floats
52 Float32Array getAsFloat32Array(); // return the matrix as a Float32Array with 16 values
53 void setUniform(in WebGLRenderingContext ctx, // Send the matrix to the passed uniform location in the passed context
56 void makeIdentity(); // replace the matrix with identity
57 void transpose(); // replace the matrix with its transpose
58 void invert(); // replace the matrix with its inverse
60 void translate(in float x, in float y, in float z); // multiply the matrix by passed translation values on the right
61 void translate(in J3DVector3 v); // multiply the matrix by passed translation values on the right
62 void scale(in float x, in float y, in float z); // multiply the matrix by passed scale values on the right
63 void scale(in J3DVector3 v); // multiply the matrix by passed scale values on the right
64 void rotate(in float angle, // multiply the matrix by passed rotation values on the right
66 void rotate(in float angle, in J3DVector3 v); // multiply the matrix by passed rotation values on the right
68 void multiply(in CanvasMatrix matrix); // multiply the matrix by the passed matrix on the right
69 void divide(in float divisor); // divide the matrix by the passed divisor
70 void ortho(in float left, in float right, // multiply the matrix by the passed ortho values on the right
73 void frustum(in float left, in float right, // multiply the matrix by the passed frustum values on the right
76 void perspective(in float fovy, in float aspect, // multiply the matrix by the passed perspective values on the right
78 void lookat(in J3DVector3 eye, // multiply the matrix by the passed lookat
80 bool decompose(in J3DVector3 translate, // decompose the matrix into the passed vector
98 Float32Array getAsFloat32Array(); // return the matrix as a Float32Array with 16 values
