3D Projectors

This tab lists only the projectors in the current 3D scene.

In the bottom toolbar you can can add a projector, search by name and delete selected projector(s).

In addition, you can activate or deactivate a projector by clicking directly on the power button next to its name.

*Tip: Double clicking in this tab automatically creates a projector.

The more actions button in the toolbar enables you to import/export the complete list of your projectors in CSV format (readable by spreadsheet programs such as Excel).

Settings

The projector has the following parameters:

Parameter	Description
Enable	Activates the projection in the scene
Position	Position of the projector in relation to its parent
Yaw	Rotation of the projector around the Y-axis
Pitch	Rotation of the projector around the X-axis
Roll	Rotation of the projector around the Z-axis
Near	Distance from which the projector sees objects (before this distance the objects do not appear in the projector’s view)
Far	Distance after which the projector no longer sees the objects (after this distance, the objects do not appear in the projector’s view)
Pin Target	Toggle to lock the center of the projection in its current place. Further moving the projector will conserve this center of projection in place.
Color	Color for the projector box, wireframe and beam
Show wire	Toggle display of the wire of the view cone and the box representing the projector according to its size parameters (see below)
Show beam	Toggle display of the projector’s beam
Test Pattern	Drop-down list of test pattern
Source	Current source (Render surface or VNode output) (see below)
Add to mask	Adds the projector in the calculation of blending masks (3D layer)
Mask group	Enables the creation of groups of masks to create separate blends
Black level	Simulates the blackness that the projector can make (0% is full black)
Aspect	Set the aspect ratio of the projector (16:9, 16:10,…)
Resolution	Pixel resolution of the projector, this value is only used in 3D study view modes
Throw ratio	Distance of projector to the screen divided by width of projection
Overscan	set in % the projector POV overscan value
Vertical shift	Vertical offset of the rendering cone in percent
Horizontal shift	Horizontal offset of the rendering cone in percent
Lumens	Luminous power of the projector, this value is only used in 3D study view modes
Stack direction	Direction (relative to the projector’s “up” arrow) in which to create the stack
Stack count	Number of projectors to add in the stack
Stack spacing	Distance between two projectors in the stack
Rotation	Applies a rotation to the projected image
Projection	Front/rear projection mode
Use database	Uses values from the database (see below)
Throw ratio min/max	Limit values for the selected lens supplied by the manufacturer (if use database is enabled)
V. shift min/max	Limit values for the selected lens supplied by the manufacturer (if use database is enabled)
H. shift min/max	Limit values for the selected lens supplied by the manufacturer (if use database is enabled)
Width	Width of the box representing the projector
Height	Height of the box representing the projector
Depth	Depth of the box representing the projector
Promote	Turns this projector into a camera
Shadow resolution	Improves the accuracy of projected shadows and on faces almost parallel to the projection (in Study Mode especially)
Cast proj. shadows	More information required.
K1-K2-K3-T1-T2	Optical distortion coefficients of the camera
Load lens calib	Load a custom lens calibration file
Custom Exposure	Enables a custom exposure setting overriding the Scene settings for the exposure on this projector
Exposure Value	Custom exposure value (If Custom Exposure is enabled)

*Note: As rotations are cumulative, it’s possible that after certain rotations the axes of rotation become confused (gimbal lock).

To remedy this, a parent node should be created to separate the rotations.

Shadow resolution

Shadow Resolution	Study Mode	Rendered Mode
256
1024
4096

For these views, Env. Map Intensity was set to 0.0 and Exposure set to 7.0

!Warning: Having many projectors enabled can impact performance, especially with high values of Shadow Resolution.

Database

---

Kinetic includes piXap’s database of projectors and lenses to perform your implantation simulations.

To use it, select the Use database checkbox. A pop-up window will open and you will be able to select the brand, model and compatible lenses from the database according to your project.

Once the projector has been set up you can still change the lens or projector at any time by clicking on the Edit button.

---

Projections

---

Kinetic Render surfaces and the outputs of VNodes can be used as projected textures in projectors.

To do this drag and drop the desired Render surface or VNode output from its panel into the Source field of the projector.

By doing this you have the possibility to play any content (video, image, live,…) directly projected into your 3D scene.

---

Drag and drop in a timeline

---

You can drag and drop any projector from your scene into one of the timelines.

This will then create a rendering layer from that projector’s point of view.

---

Drag and drop in a graph

---

You can drag and drop any projector from your scene into a graph.

You will then have access to the different values of the projector, in read or write mode.
