Circle TOP
Summary
The Circle TOP can be used to generate circles, ellipses and N-sided polygons.
The shapes can be customized with different sizes, rotation and positioning. An optional border can be added to the shape. Background, border and fill colors can all be set independently. Anti-aliasing can be turned on or off.
You can use the arc angles to cut out part of the shape. In the case of polygons, the number of visible sides will be preserved no matter how much is cut out.

- Half
half- Multiply the input's resolution by that amount.
- 2X

limit- Limit the input resolution to be not larger than this resolution, while keeping the aspect ratio the same.
- Custom Resolution
custom- Directly control the width and height.
Resolution
resolution - ⊞ - Enabled only when the Resolution parameter is set to Custom Resolution. Some Generators like Constant and Ramp do not use inputs and only use this field to determine their size. The drop down menu on the right provides some commonly used resolutions.
- W
resolutionw-
- H
resolutionh-
Use Global Res Multiplier
resmult - Uses the Global Resolution Multiplier found in Edit>Preferences>TOPs. This multiplies all the TOPs resolutions by the set amount. This is handy when working on computers with different hardware specifications. If a project is designed on a desktop workstation with lots of graphics memory, a user on a laptop with only 64MB VRAM can set the Global Resolution Multiplier to a value of half or quarter so it runs at an acceptable speed. By checking this checkbox on, this TOP is affected by the global multiplier.
Output Aspect
outputaspect - ⊞ - Sets the image aspect ratio allowing any textures to be viewed in any size. Watch for unexpected results when compositing TOPs with different aspect ratios. (You can define images with non-square pixels using xres, yres, aspectx, aspecty where xres/yres != aspectx/aspecty.)
- Use Input
useinput- Uses the input's aspect ratio.
- Resolution
resolution- Uses the aspect of the image's defined resolution (ie 512x256 would be 2:1), whereby each pixel is square.
- Custom Aspect

Aspect
aspect - ⊞ - Use when Output Aspect parameter is set to Custom Aspect.
- Aspect1

Input Smoothness
inputfiltertype - ⊞ - This controls pixel filtering on the input image of the TOP.
- Nearest Pixel
nearest- Uses nearest pixel or accurate image representation. Images will look jaggy when viewing at any zoom level other than Native Resolution.

linear- Uses linear filtering between pixels. This is how you get TOP images in viewers to look good at various zoom levels, especially useful when using any Fill Viewer setting other than Native Resolution.
- Mipmap Pixels
mipmap- Uses mipmap filtering when scaling images. This can be used to reduce artifacts and sparkling in moving/scaling images that have lots of detail.
Fill Viewer
fillmode - ⊞ - Determine how the TOP image is displayed in the viewer.
NOTE:To get an understanding of how TOPs work with images, you will want to set this to Native Resolution as you lay down TOPs when starting out. This will let you see what is actually happening without any automatic viewer resizing.
- Use Input

- Fill
fill- Stretches the image to fit the edges of the viewer.

Viewer Smoothness
filtertype - ⊞ - This controls pixel filtering in the viewers.
- Nearest Pixel
nearest- Uses nearest pixel or accurate image representation. Images will look jaggy when viewing at any zoom level other than Native Resolution.
- Interpolate Pixels
linear- Uses linear filtering between pixels. Use this to get TOP images in viewers to look good at various zoom levels, especially useful when using any Fill Viewer setting other than Native Resolution.
- Mipmap Pixels
mipmap- Uses mipmap filtering when scaling images. This can be used to reduce artifacts and sparkling in moving/scaling images that have lots of detail. When the input is 32-bit float format, only nearest filtering will be used (regardless of what is selected).
Passes
npasses - Duplicates the operation of the TOP the specified number of times. For every pass after the first it takes the result of the previous pass and replaces the node's first input with the result of the previous pass. One exception to this is the GLSL TOP when using compute shaders, where the input will continue to be the connected TOP's image.
Channel Mask
chanmask - Allows you to choose which channels (R, G, B, or A) the TOP will operate on. All channels are selected by default.
