Calibration/Camera Keystone

Allows to select an area of interest in a camera feed and to remap it to another texture ​

Description

The Camera Keystone box allows to select an area or interest in a texture while in Play mode using four control points. The selected texture will be remapped on the Content resolution when outputted.

Inputs

Texture 2D Texture Receives the texture to be keystoned.

Outputs

Texture 2D Render Target Outputs the selected texture on the Content resolution.

Parameters

Format

Channel Settings

Set Format Toggle Allows the box to change the format of the outputted texture. Once enabled, this creates a new memory allocation for the texture created.
Format String Sets the format of the outputted texture. RGBA 8 bits is the common format. RGBA 16 bits allows negative vector calculation and is mostly used for simulation. RGBA 32 bits allows high precision but may negatively affect the FPS and the Grayscale has only the Red component.
Format Components String Sets the Components used for the outputted texture.
Format Component Bit Depth String Sets the Bit Depth of the outputted texture. 8 bits is the common format, 16 bits allow negative vector calculation and is mostly used for simulation, 32 bits allow high precision but may negatively affect the FPS.
Format Component Type String Sets the pixels value type depending on the Bit Depth.

Canvas Settings

Set Resolution Toggle Allows the box to change the resolution of the outputted texture. Once enabled, this creates a new memory allocation for the texture created.
Resolution Mode String Sets the Resolution Mode. Canvas uses the project configuration settings, Custom uses local setting resolution not shared with other box and Project Aspect Ratio uses the project aspect ratio and proportionally scales the height and width. The parameter chooses the reference Canvas setting the resolution of the outputted texture.
Canvas 2D ResolutionRef Chooses the reference Canvas and sets the resolution of the outputted texture.
Maximum Resolution Int Sets the maximal resolution of the X-axis and calculates the resolution of the Y-axis based on the aspect ratio of the Content Canvas.
Lock Aspect Ratio Toggle Locks the Aspect Ratio for Custom resolution.
Aspect Ratio 2D ResolutionRef Chooses the reference Canvas for the aspect ratio.
Size XY Int2 Sets the size in pixels of the outputted texture.
