Softeq delivered a watercolor drawing simulating app with CUDA-powered calculations and OpenGL-based output. Processing contains five kernels:

  • Block kernel calculating each square tile of the paper
  • Flow kernel calculating watercolor flow in each direction
  • Sleep kernel is a block kernel but it contains only drying processes (not flow)
  • Collide kernel calculating flow collisions
  • Render kernel building up the final texture that is rendering out by means of OpenGL

How can we help you?
