Hi everyone! I'm Digilinx, and this is a guide to using The perspective plugin
The main purpose of the plugin - the creation of virtual space inside static images, or video with a static camera. I'll show you how it works!
We creating a composition
add a footage, and add a plugin.
You can find it in the effects tab, under the digilinx plug-ins folder.
After adding the plugin, you will be in perspective creation mode.
Creation mode is enabled and disabled with this check box.
There are 3 algorithms for creating perspectives: room, cone and conical flustrum.
If your picture looks like a room, hall, may be an urban area
in other words If there are 5 planes in your footage, choose the room type
in our image the left and right planes are houses, the upper one is the sky, the lower one is the water channel
and back cover is horizont. We choose a room.
for the room type, the perspective is formed on the basis of 8 points
4 points - the back cover of the room and 4 projection points - to determine the planes of the room.
So, let's create a perspective!
All points are placed, now we exit the creation mode.
So, you see green lines, it means that the plugin is not registered.
To register, click on REGISTER and enter your PURCHASE CODE from ENVATO LICENSE CERTIFICATE
more detailed information on installing the plugin and finding PURCHASE CODE, you can find in the documentation.
Please note, Internet access is required for product registration.
We copy and paste a PURCHASE CODE and click OK
wait a bit.. And we see. plugin is registered!
You can always visually see the depth of the image using the view depth popup. We choose lines and see red lines are close areas
green lines -far areas.
come back!
Let's go to the image manipulation.
The plugin has a built-in camera, which is very similar to composition camera. We can change Camera Zoom,
Point of Interest
Camera Position
Rotations
Also you can manage using the composition camera. To do this, set the 3d layer
and add a new layer - the camera.
and turn on the external camera checkbox.
Now the image changes when you change the settings of the external camera.
To illustrate depth parameters, I will create a new layer at 0 z-coordinate and create a grid.
If we move camera, we can see how virtual depth is created.
The depth value may be negative, in which case the image becomes convex.
death can be aligned before and after the footage, here Before footage
and after footage. If you planing to place different objects inside to our 3d virtual image, you should choose before footage.
Transform position and transform scale differ from the standard parameters in that
the offset and scale occurs during image processing. See the difference!
Stretching and twisting are used for distort image space and create different effects
The Motion tile is used to add a mirror image.
Look, we move the camera and see the black areas. If we add a motion tile,
the areas are painted with a mirror image, this can be useful for various effects
Sometimes the processing image is larger than the original
Expand output allows to add points to resultant image
Be careful! large values slow down the rendering significantly!
Now I will tell you about the cone algorithm, for this we create a new composition, add the footage and the plugin.
Select the CONE type.
The perspective is created by 2 points in the back of the Eclipse (center and radius) and 4 points in the projection lines.
OK, Exit Creation mode.
Create a camera. Copy Grid from previouse comp
In fact, it is not a clean cone that is created, but a 
elliptical paraboloid-like surface
the surface view is determined by the distance between the ellipsoidal section and the extreme point of the surface.
You can change this value by “Gaussian Curvature”
If the value is 100, the surface is more like a classic cone,
if reduced, the surface will be more like a sphere.
If you choose the type of conical flustrum, the back cover will appear.
This type is necessary when your image has some object in the distance and you would not want them to change.
Let me show you another example.
Here we see mountains, if we apply the CONE type, we see that a hole appears in the mountain
if we use the CONICAL FRUSTRUM, and change the space, the mountain remains unchanged.
Let's make some animation
Thats' all. Enjoy using the plugin! bye-bye
