fromScene method

dynamic fromScene(dynamic scene, [ dynamic sigma = 0, dynamic near = 0.1, dynamic far = 100, ])

• Generates a PMREM from a supplied Scene, which can be faster than using an
  • image if networking bandwidth is low. Optional sigma specifies a blur radius
    • in radians to be applied to the scene before PMREM generation. Optional near
    • and far planes ensure the scene is rendered in its entirety (the cubeCamera
    • is placed at the origin).

Implementation

fromScene(scene, [sigma = 0, near = 0.1, far = 100]) {
  _oldTarget = _renderer.getRenderTarget();

  _setSize(256);
  var cubeUVRenderTarget = _allocateTargets();
  cubeUVRenderTarget.depthBuffer = true;

  _sceneToCubeUV(scene, near, far, cubeUVRenderTarget);
  if (sigma > 0) {
    _blur(cubeUVRenderTarget, 0, 0, sigma, null);
  }

  _applyPMREM(cubeUVRenderTarget);
  _cleanup(cubeUVRenderTarget);

  return cubeUVRenderTarget;
