This parameter is useful when producing spatial effects that need to be invariant to the pixel scale, especially when using X and Y coordinates. Dimensions of image from input N, e. If one of these conditions does not hold, all frames from the specified input frame range are asked for. A custom 2-dimensional variable that can be referenced in the expression by its script-name, pos5. If checked, update the parameter values during interaction with the image viewer, else update the values when pen is released. The output region is the region of definition of input

The output region is the region of definition of input 2. The output region is the region of definition of input 5.

Expressions can be seen as a way of allowing customization of inner loops. Then the user could write. Y coordinate in pixel units of the pixel to render. A custom 2-dimensional variable that can be referenced in the expression seeexpr its script-name, pos6.

Current frame being rendered CsAs: Another demonstration seexppr the expression editor can be seen in this video YouTube at seexlr 3: X coordinate normalized in the [0,1] range of the output pixel to render. SeExprSimple has one scalar expression per channel, and the source channels may also be accessed through scalars rgba. Artistic control is very important for film making.

A few pre-defined variables and functions were added to the language for filtering and blending several input images. Scale at which the image is being rendered.

SeExpr Language Reference

The output region is the intersection the regions of definition of all connected inputs. The output region is the union of the regions of definition of all connected inputs.

For example, the parameter x1 can be referenced using x1 in the script: Only used if the frame range cannot be statically computed from the expression. At the same time it is sometimes nice to prototype seexpf and techniques in expressions because of the interactivity. The output region is the region of definition of input 3.

As an example, a programmer could allow a user to generate an image by evaluating an expression at each point of the image and binding a u and v variable for the u,v parameter of the image.

Also, libraries of expressions are created by expert users and shared with other users.

Similarly, in alpha only, the RGB script will not be executed. The output region is the region of definition of input 2 Input3 input3: The output region is the region of definition deexpr input 6.

More recently, we have integrated it as a way of defining procedural controls to physical dynamical simulations and render time particle instancing. Developers have enjoyed them too for quick prototyping and deployment of fixes to production needs. The output region is the size of the rectangle overlay. The output region is the region of definition of input 5 Input6 input6: Later it was integrated into paint3d, our texture painting facility, which opened the door to procedural seex;r.

Read the Docs v: Being able to embed an expression language in seexpe piece of custom software allows an amazing degree of artistic freedom.

The pixel aspect ratio. This is contrast to scripting which is mostly aimed at gluing large parts of code base together. A custom 2-dimensional variable that can be referenced in the expression by its script-name, pos The output region is the region of definition of input 9. Color RGB vector and seexr scalar of the image from input N, e.
