Team Vuo posted a new Composition, “Warp Image with Projection Mesh Demo

Warp Image with Projection Mesh Demo

This app demonstrates the Pro node Warp Image with Projection Mesh. Even if you do not have Vuo Pro, you will be able to run the app. Only Vuo Pro users will be able to run the composition.

Patterns in 'Make Noise Image' output for certain seeds

Status: 

Vuo version: 

Steps causing the bug to occur: 

Reported by Kewl on Make Noise Image: how many bits?.

OK, with the NVIDIA GeForce GT 750M, I'm seeing patterns emerging past [a seed of] a hundred or so. So, I'm using a shorter sequence of 67 seeds but randomly flipping and inverting the images.

'Render Image to Window' doesn't render image if less than 4px in height

Status: 

Vuo version: 

Fixed in Vuo version: 

Steps causing the bug to occur: 

As reported by bLackburst on Make Noise Image Range doesn't cover small resolutions:

Also if you render this [1-pixel-high] image to a window you will notice that the window doesn't display this line unless the window is resized.

API documentation says library file extension is optional, but it's actually required

Status: 

Fixed in Vuo version: 

Steps causing the bug to occur: 

On ARToolkit node github repository, mic reported that adding the library libAR.a to a module's dependencies as "dependencies" : [ "AR" ] doesn't work, but adding it as "dependencies" : [ "AR.a" ] does. This contradicts the documentation, which says that either should work.

For some libraries (those within Vuo.framework?), both options do work. Team Vuo should either allow both options for all libraries or fix the documentation.

Have you found a workaround?: 

Include the file extension.

UV texture coordinate math expressions in 'Make Parametric Grid Mesh' node

(Created on behalf of unicode from Make Parametric Grid Mesh node doesn't conform to documentation.)

Add input ports U Expression and V Expression that allow specifying arbitrary UV texture mappings independent of the mesh's shape in XYZ space.

Examples of how this would be useful (details here):

  • scrolling an image around a curved surface
  • wrapping world-map images of various projections onto a sphere
