Summary
[edit]

The Sprite SOP creates geometry (quad sprites) at point positions defined by the CHOP referenced in the XYZ CHOP parameter.

Parameters - Page

XYZ CHOP xyzchop - A CHOP with 3 channels is required to specify the X, Y, and Z position of the quad to be generated. Each sample creates 1 quad. The created quads are centered at the points defined by each sample.  

Camera camera - The geometry will always face the Camera COMP specified here.  

Width CHOP widthchop - A 1 channel CHOP can be specified to set the width of the quad at that sample.  

Color CHOP colorchop - A 3 channel CHOP can be specified to set the R, G, and B color values of the quad at that sample.  

Alpha CHOP alphachop - A 1 channel CHOP can be specified to set the alpha of the quad at that sample.  

Perspective Width perspectivewidth - The width of the geometry created. This parameter only has an effect when the Use Constant Width is less that 1.0.  

Use Constant Width constantwidth - This blends between using Perspective Width and Constant Width. When Use Constant Width = 0, width is determined only by Perspective Width, when Use Constant Width = 1, width is determined only by Constant Width parameters below.  

Constant Width Near constantwidthnear - The width used for quads located at a position Constant Width Falloff Start or closer.  

Constant Width Far constantwitdhfar - The width used for quads located at a position Constant Width Falloff End or farther.  

Constant Width Falloff Start falloffstart - At this position the or closer the geometry uses the Constant Width Near parameter for its width.  

Constant Width Falloff End falloffend - At this position the or farther the geometry uses the Constant Width Far parameter for its width.

NOTE: Inbetween Falloff Start and Falloff End the width is determined using a half-cosine falloff between the two values.
