Surface Based Rendering

Surface Based Rendering:
1- Isovalues ranges for Skin and Bone: - In order to animate the surfaces of skin and bone, we loop between different isovalues, until we determine the best isovalues range for the skin which is in our project is from 500 to1000 and from 1000 to 3000 for bone.

2- Setting up the camera object parameters: - To control the view direction, we did this by setting SetFocalPoint 0 0 0, and set position method with the parameter SetPosition 0 1 0, now also we need to control the camera movement, we set the camera parameter that determine the movement of the camera by Dolly 1.5, Dolly will move the direction of the camera along the direction of projection, moving towards the focal point.

3- Writing Multiple Tiff images: - we create image file showing the content of the render window, in order to do this we create separate button in our GUI that invoke the vtkTIFFWritter to set the input for VtkWindowToImageFilter, so finally we obtain the output Tiff image.
