EX9.Dataflow

French | Italian | Spanish | Japanese

The overall dataflow of the 3d rendering pipeline in vvvv looks as follows:

vvvv passes several data to the graphics card:

  • Mesh
  • Texture
  • User defined variables
  • Render Sates
  • Transform matrices

First the vertexshader programm is applied to each vertex. Its major task is to project the geometry onto the screen. The output is the vertex position in screenspace for the rasterizer and other data for the pixel shader.

Between vertexshader and pixelshader the conversion from vector graphics to pixel graphics happens. This is done by the rasterizer, that calculates which screen pixels belong to the geometry. It also interpolates per-vertex data sent from the vertex shader to per-pixel data for pixels which lie between the vertices.

Then the pixelshader programm is executed for every visible pixel, as defined by the rasterizer. It calculates the final color of the pixel.

manuelgonzalvez: @levi thanks would love to! anyway managed to get something similar working based on forum search and anthokio's patches.

levi: @ravasquez thanks. 31.2 x86 verrion worked. @manuelgonzalvez i have a dx11 projectTexture if u a want.

ravazquez: @levi not sure bout the ImagePack, but I believe VL.OpenCV should give you the same tools and should work with beta just fine

levi: anyone knows of a VVVVpacks.image that works for elliot's projector calibration patches?x64,dx11. always crashes v4 on solve.

Lorenz: VJing with GIFS: https://lorenzpotthast.de/gifjockey/ A fun little side project, that I first prototyped in v4 and now turned web-based ;)
