setMatrixUniforms

This function performs the mapping:

function setMatrixUniforms() {  if (coordinates === WORLD_COORDINATES) {    mat4.invert(cameraMatrix, modelViewMatrix);    gl.uniformMatrix4fv(program.uModelViewMatrix, false, modelViewMatrix);  }  else {    mat4.invert(modelViewMatrix, cameraMatrix);  }  gl.uniformMatrix4fv(program.uProjectionMatrix, false, projectionMatrix);  gl.uniformMatrix4fv(program.uModelViewMatrix, false, modelViewMatrix);  mat4.transpose(normalMatrix, cameraMatrix);  gl.uniformMatrix4fv(program.uNormalMatrix, false, normalMatrix);}
