Feedback

From RealMotion Wiki

Simulation/Feedback

Performs feedback simulation based on copies of textures. ​

Description

The Feedback box generates different types of feedback by copying the inputted texture over time and space.

Note: The Feedback box must receive a texture with an alpha component because the blending is made with the component alpha.

Inputs

Texture 2D Texture Receives the texture to be processed. The texture must have an alpha component.

Outputs

Texture 2D Render Target Outputs the result of the simulation in a texture.

Parameters

Feedback

Feedback Mode String Sets the simulation mode used. The Kaleidoscope mode adds a rotation and a scale at each copy of the inputted texture. The Trail mode copies the inputted texture and adds that copied texture with a delay. The Grid copies and divides the resolution of the inputted texture on itself.
Angle Float Sets the angles of rotation for each texture copy.
Scale Float Sets the scale factor for each texture copy.
Attenuation Factor Float Sets the value multiplied by the value of each texture copy.
Max Buffer Resolution Int Sets the maximal resolution of the buffer. The Buffer Resolution determines the size of the copied texture and affects the memory usage directly.
Trail Delay Int Sets the frame delay between two trails.
Trail Iterations Int Sets the amount of trail iterations.

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.

Alpha

Set Alpha Toggle Enables the alpha overwrite.
Alpha Float Sets the alpha value to override with.
