Source space Target space Example: Image moved in X-axis direction The direction of movement differs as follows in source space and target space. Source space Target space Local space and global space There are two types of DME coordinate space: local space and global space. Local space: Coordinates that are local to each DME channel Global space: Coordinates that are common to all channels By switching from local space to global space, you can add additional movement to the movement of images in individual channels, and also add transform effects to multiple channels that have been combined using global effects. Example: Rotation around Y-axis Rotation around Y-axis in local space Rotation around Y-axis in global space Three-dimensional parameters Three-dimensional parameters have X, Y, and Z values which define the position of an image, its axis of rotation, the position of the virtual viewpoint of the image, and so on. On a 16:9 monitor screen, the reference values of parameters for the image (source space) and screen (target space) are as follows. Center of image or screen: X = 0.00, Y = 0.00, Z = 0.00 Upper right corner of image or screen: X = 16.00, Y = 9.00, Z = 0.00 Lower left corner of image or screen: X = -16.00, Y = -9.00, Z = 0.00 Y-axis +9.00 Z-axis + X-axis -16.00 +16.00 X-axis Z-axis - -9.00 Y-axis The Z-axis direction is + behind the image or screen, and - in front of the image or screen. Three-dimensional parameter setting values The parameter value setting ranges and defaults are as follows. Operation Move image (Location XYZ) Rotate image (Rotation) (Spin) Move rotation axis (Axis Location) Scale image (Location Size) Change image aspect ratio (Aspect (X) (Y)) Change image aspect ratio (Aspect (Z)) Change viewpoint position (Perspective (X) (Y)) Change viewpoint position (Perspective (Z)) Change image skew (Skew) Setting range Default -999.9999 to +999.9999 0.0000 -999.9999 to +999.9999 0.0000 -999.9999 to +999.9999 0.0000 0.0000 to 999.9999 1.0000 0.0000 to 999.9999 1.0000 0.0000 to 2.0000 1.0000 -999.9999 to +999.9999 0.0000 0.0000 to 999.9999 1.0000 -9.9999 to +9.9999 0.0000 195
