Version 3.3

Features Attributes and Functions

To explain the layer effect engine it is illustrative to imagine grandMA VPU as a model of a several movable cameras where every camera looks at a layer object like a 2D plane or a 3D cube.

In these examples an image may be a texture (picture), or a video.

 

Layer Features and Attributes Example  
  with values in %  
Dimmer Dimmer 50 % Dimmer 100 %
Dimmer function. To facilitate fading between different layers the dimmer controls the transparency of an object.
If the dimmer is 0 the object is transparent and the projection is invisible.
If the dimmer is “full” the object is opaque and you can only see the front layer (front Z-position)
MixColor (R; G; B) Color (0,0,0) Color(100,100,0)
Tint the output with the RGB (Red; Green; Blue)color mixer
HSBC (Hue shift, Saturation, Brightness + Contrast) HSBC (50,50,50,50)
  HSBC (50,0,50,50)
Set Hue, Saturation and Brightness of a layer
Colorkey   Layer 2 Key R,G,B (100,0,0)
Tol (10)
  Image Layer 1 Image Layer 2
Set the transparency for the foreground object.
First select the color then set the tolerance.   Resulting Output Image
The switch 'Alpha’ decides if the pixel gets complete transparent or opaque in dependency to the color key.  
The switch 'Type’ decides if the calculation is done in the RGB (Red Green Blue) or HSB (Hue Saturation Brightness) model.    
Colorboost (ColBoost-R; -G; -B) ColBoost (50,50,50) ColBoost (50,50,100)
Manipulate the intensity of red, green or blue color of the image separately.
Borders    
  soft Borders hard Borders
(Left Hard, Left Soft, Right Hard…Top Hard, Top Soft) Borders can be used for realizing PiP (picture in picture) applications.
Softborder works with alpha channels so that the layer underneath can even shine through the top layer to merge the layers.
For example first cut the layer to a smaller size (which is NOT scaling!) and then create a soft edge by using the soft parameter for the respective side of the layer.
This makes the layer underneath shine through (see picture).
Borders also can be changed via the special dialog in the desk:
Therefore select the layer, select the feature 'Border' and press the button 'Special Dialog' at the desk.
VObj. (3D-Objects) cross sphere
Select an 2D or 3D object on which surface the image or video is shown
VObj (Transistion Type)

The transistion time can be set from 0….3600 seconds    
VObj. I-Pool Pool ‚Standard’ selected Pool ‚Video Test2’ selected
Selection of the 'I-Pool’. One ‚Pool’ can contain up to 255 images or videos
VObj. Images Image 1 Image 2

Animate continuous scrolling of the image or video on the object
VPlayer (Playmode Speed; Begin; End; Index) Frame 100 Frame 200

Frame Index: Select a single frame with the Index channel 
Play: Starts the Video once forward from the beginning to the end 
Stop: Stops immediately Pause: Pauses 
Resume: Continues after Pause (even with the Looping) 
Play Index: Plays the video from the index frame which has to be set first

With the beam shapers the resulting image can be masked variable with four shapers each with 2 channels A and B.
  Video  
VObj (Images) Image = no Image Image = Circle
Select the omage for the iris mask
VScale (X; Y; Z; All) X= 50%; Y=50%; Z=50% X= 50%; Y=30%; Z=50%
     
Scale the dimensions of the object in X; Y ;Z direction
VImg (Split X; Y Offset X; Y) Split X 0; Split Y 0 Split X 2; Split Y 2
Split the image in X and Y. Split offset of the image.  
This offset can be understood as the Point of View (PoV).
By using this function the perspective doesn´t change.
Try this with the cube and you will clearly see the difference!
 
VCamPos (X; Y; Z) X=50%;Y=50%;Z=50% X=46%;Y=52%;Z=54%
All layer views are mixed up to one view for the main cameras whose images are send to the physical outputs.
These imaginary cameras can be moved to show only parts of the whole image.
So several applications can be connected together to project a huge image.
If the camera position moves the perspective changes: Take a cube, rotate it a bit and then move the camera.
You can see that the perspective changes - you can see that the „world´s“center is still the centre of your monitor.
VCamRot (X; Y; Z)    
Rotate the camera around its own centerpoint    
VEffect 1…...4 (Eff Type; Eff part) Eff Type = 0 Eff Type = Sepia
Several effects based on the Direct3D standard can be selected.
Effects are defined within .fx files as described in Content: Eff1 Type…Eff4 Type.
3D Key (PosX;Y;Z Rot X;Y;Z Scale X;Y;Z; All)    
Select a 3D object for the camera.
This is useful to manipulate the complete output e.g. for projecting on a cyclorama or display all layers on a sphere.
 
   
Keystone (1A,; 1B; 2A; 2B; 3A; 3B; 4A; 4B) 1A=0; 1B=0; 2A=0; 2B=0; 3A=0; 3B=0; 4A=0; 4B=0 % 1A=0; 1B=0; 2A=0; 2B=30; 3A=0; 3B=0; 4A=0; 4B=30 %
All layer views are mixed up to one view for the main camera.
Each edge of this view can be moved towards the opposite edge to generate a keystone effect.
Keystone Corr. (X - Corr.; Y - Corr.) X Corr. = 0 %; Y Corr. = 0 % X Corr. = 75 %; Y Corr. = 0 %
If a picture is projected distorted on a surface, a perspective correction is necessary
to distribute the content on the surface correctly.
Therefore the distribution of the picture content can be manipulated in X- and Y-direction.
Softedge (1A,; 1B; 2A; 2B; 3A; 3B; 4A; 4B) 1A=0; 1B=0; 2A=0; 2B=0; 3A=0; 3B=0; 4A=0; 4B=0 % 1A=0; 1B=0; 2A=50; 2B=0; 3A=0; 3B=0; 4A=0; 4B=0 %
If several projectors should show one common image, the borders must be cross faded.
For every border one channel for the position and one channel for the dispensation of the black wedge exist.
This example shows a soft edging for the left border of the image.
Splitscreen (Offset X; Offset Y)    
Changing the X or Y offset doesn't change the point of view. Camera axis stays on the object axis.
This is different from VCamPos.
CP-X, CP-Y, CP-Z
Rotate the camera around the center point of the 3D-world
FOV
Change the field of view of the camera.
