Summary
[edit]

The SVG TOP loads SVG files into TouchDesigner. This operator only works with Nvidia GPUs.

See also the Web Render TOP.

Parameters - Load Page

File file - The path and name of the SVG file to load. File format .svg supported.

DAT dat - Not currently used.

Reload reload - Change from 0 to 1 to force the file to reload, useful when the file changes or did not exist at first.

Anti-Alias antialias - - Sets the level of anti-aliasing in the scene. Setting this to higher values uses more graphics memory.

Background Color bgcolor - Sets the background color in the image.

  • Red bgcolorr -
  • Green bgcolorg -
  • Blue bgcolorb -

Background Alpha bgalpha - Sets the background alpha in the image.  


Parameters - Transform Page

Transform Order xord - - The menu attached to this parameter allows you to specify the order in which the changes to your TOP will take place. Changing the Transform order will change where things go much the same way as going a block and turning east gets you to a different place than turning east and then going a block.

  • Scale Rotate Translate srt -
  • Scale Translate Rotate str -
  • Rotate Scale Translate rst -
  • Rotate Translate Scale rts -
  • Translate Scale Rotate tsr -
  • Translate Rotate Scale trs -

Rotate Order rord - - The rotational matrix presented when you click on this option allows you to set the transform order for the TOP's rotations. As with transform order (above), changing the order in which the TOP's rotations take place will alter the TOP's final position.

  • Rx Ry Rz xyz -
  • Rx Rz Ry xzy -
  • Ry Rx Rz yxz -
  • Ry Rz Rx yzx -
  • Rz Rx Ry zxy -
  • Rz Ry Rx zyx -

Translate t- - The two fields for Translate allows you to specify transforms in x and y axes.

X tx -


Y ty -

Translate Unit tunit - -

Rotate r- - The three fields for Rotate allow you to specify the amount of rotation along any of the three axes.

X rx -


Y ry -


Z rz -

Scale s- - The two fields for Scale allows you to specify transforms in x and y axes.

X sx -


Y sy -

Pivot p- - The Pivot point edit fields allow you to define the point about which the TOP scales and rotates. Altering the pivot point of a TOP produces different results depending on the transformation performed on the TOP image.

For example, during a scaling operation, if the pivot point of a TOP image is located at -1,-1 and you wanted to scale the image by 0.5 (reduce its size by 50%), then the TOP would scale toward the pivot point and appear to slide down and to the left.

Parameters - Common Page

Output Resolution outputresolution - - quickly change the resolution of the TOP's data.

  • Use Input useinput - Uses the input's resolution.
  • Eighth eighth - Multiply the input's resolution by that amount.
  • Quarter quarter - Multiply the input's resolution by that amount.
  • Half half - Multiply the input's resolution by that amount.
  • 2X 2x - Multiply the input's resolution by that amount.
  • 4X 4x - Multiply the input's resolution by that amount.
  • 8X 8x - Multiply the input's resolution by that amount.
  • Fit Resolution fit - Multiply the input's resolution by that amount.
  • Limit Resolution limit - Multiply the input's resolution by that amount.
  • Custom Resolution custom - Enables the Resolution parameter below, giving direct control over 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.

Resolution Menu resmenu -

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 custom - Lets you explicitly define a custom aspect ratio in the Aspect parameter below.

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

Aspect1 aspect1 -


Aspect2 aspect2 -

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.
  • Interpolate Pixels 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 useinput - Uses the same Fill Viewer settings as it's input.
  • Fill fill - Stretches the image to fit the edges of the viewer.
  • Fit Horizontal width - Stretches image to fit viewer horizontally.
  • Fit Vertical height - Stretches image to fit viewer vertically.
  • Fit Best best - Stretches or squashes image so no part of image is cropped.
  • Fit Outside outside - Stretches or squashes image so image fills viewer while constraining it's proportions. This often leads to part of image getting cropped by viewer.
  • Native Resolution nativeres - Displays the native resolution of the image in 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.

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.

Pixel Format format - - Format used to store data for each channel in the image (ie. R, G, B, and A). Refer to Pixel Formats for more information.

  • Use Input useinput - Uses the input's pixel format.
  • 8-bit fixed (RGBA) rgba8fixed - Uses 8-bit integer values for each channel.
  • sRGB 8-bit fixed (RGBA) srgba8fixed - Uses 8-bit integer values for each channel and stores color in sRGB colorspace.

An that creates, composites and modifies images, and reads/writes images and movies to/from files and the network. TOPs run on the graphics card's GPU.

An that manipulates text strings: multi-line text or tables. Multi-line text is often a command , but can be any multi-line text. are rows and columns of cells, each containing a text string.

The width and height of an image in pixels. Most TOPs, like the can set the image resolution. See for the width/height ratio of an image, taking into account non-square pixels.

The viewer of a node can be (1) the interior of a node (the ), (2) a floating window (RMB->View... on node), or (3) a that graphically shows the results of an operator.

A outputs one or more channels, where a channel is simply a sequence of numbers, representing motion, audio, etc. Channels are passed between CHOPs in TouchDesigner networks. See also .
