Graphics Engine Functions
Object Graphic Functions
For an individual object, you can control:
• The media file and 3-D object selection for the layer
• Media playback including
— What portion of the movie plays
— Playback speed
— Playback mode (direction and style of playback)
• The object transparency (opacity)
• Visual Effects including colormixing and geometric effects
• Synchronization
• Image Rotation, Scale and Position
Global Functions
Global controls are applied to composite image created by multiple 3-D images. For the
combined image, you can:
• Adjust the composite image intensity level
• Apply visual effects including colormixing and geometric effects
• Select a mask shape, size it and apply edge fades and color to the mask
• Apply and color mix an image edge fade
• Control keystone correction
• Establish the point in 3-D space from which image will be viewed
Making Graphics Effect Choices
Because you have control of many parameters, there are sometimes several ways to accomplish
the same look. For Example, to make an object appear larger, you can scale it along the x, y
and z axis, or you can apply a global control to zoom in on the z axis from a viewpoint that
makes the object seem to increase in size.
Which solution you choose depends, to a large extent, on the transition to other effects you
want to achieve.
