EX9.HLSL.Semantics

Following semantics for parameters in Effect-Files are currently supported in vvvv. All Semantics are case-insensitive.

semantic	description	type
world	holds the transformation connected to the "Transform" pin. multiply the points of your mesh with that matrix so that you can transform meshes in space.object space -> world space	float4x4
worldinverse	the inverse of the world matrixworld space -> object space *	float4x4
worldtranspose	the transpose of the world matrix *	float4x4
worldinversetranspose	the transpose of the inverse of the world matrix *	float4x4
view	this is the transformation you connected to the renderer at pin "View Transform". this matrix normally holds the position and orientation of the camera. multiply the points of your mesh to get them relative to the camera. still no distortion has taken place. after multiplication x goes right, y goes up and z goes into the monitor.world space -> view space	float4x4
viewinverse	view-inverse-matrix	float4x4
viewtranpose	view-tranpose-matrix	float4x4
viewinversetranspose	view-inverse-transpose-matrix	float4x4
projection	this is the transformation you connected to the renderer at pin "Projection Transform". it normally holds a perspective transformation. multiply the points of your mesh to distort them by a lens. after multiplication x and y values in between -1 and 1 are visible in the renderer. points wiht z=0 are in front (NearClipping Plane), points with z=1 are behind (Far Clipping Plane).view space -> projection space	float4x4
projectioninverse	projection-inverse-matrix	float4x4
projectiontranpose	projection-tranpose-matrix	float4x4
projectioninversetranspose	projection-inverse-transpose-matrix	float4x4
worldview	world-view-matrix. shortcut to get fromobject space -> view space with one matrix multiplication *	float4x4
worldviewinverse	world-view-inverse-matrix *	float4x4
worldviewtranspose	world-view-transpose-matrix *	float4x4
worldviewinversetranspose	world-view-inverse-transpose-matrix *	float4x4
viewprojection	view-projection-matrix	float4x4
viewprojectioninverse	view-projection-inverse-matrix	float4x4
viewprojectiontranspose	view-projection-matrix	float4x4
viewprojectioninversetranspose	view-projection-inverse-transpose-matrix	float4x4
worldviewprojection	world-view-projection-matrix. very comfortable matrix to get points from the original mesh relative to the camera and also distorted by its lens.object space -> projection space *	float4x4
worldviewprojectioninverse	world-view-projection-inverse-matrix *	float4x4
worldviewprojectiontranspose	world-view-projection-transpose-matrix *	float4x4
worldviewprojectioninversetranspose	world-view-projection-inverse-transpose-matrix *	float4x4
cameraposition	the cameraposition	float3
texturematrix	use this to get a vvvv style symmetric texture transformation	float4x4 (or float3x3)
viewportindex	the index of the currently drawn viewport	int
viewportcount	how many viewports the renderer draws	int
targetsize	size of the rendertarget in pixels	float2
invtargetsize	1 / targetsize	float2
color	use this to get a vvvv style colorpin	float4

* if you don`t declare a world-matrix in your effect, but want to make use of any of the world-view-projection-matrices (those matrices you need a world-matrix for to calculate, like "worldview" or "worldviewprojection"), a matrix-pin for the world-matrix will automatically be added (the "Transform Pin") to your effectnode (with the identity matrix as default value).
