v1.0.3 Alpha Release Notes

In this new release sphere geometry type is supported. There are also many improvements, new features and bug fixes.

New features

  • Supporting vector fields for volume color (default is "Cd")
  • Added support for noise based procedural volumes
  • Depth of field plane visualizer for easy control of focal point
  • Volume depth aov is written in exr files as a layer
  • Spheres are now supported in VPT
  • Whole project now uses boost::filesystem for OS agnostic directory and file creation
  • New fileIO classes for saving and loading many types of texture files (.png, .tga, .exr etc)
  • Atmosphere system now saves precomputed textures and loads at start if they are present
  • Residual ratio tracking for transmittance estimation
  • New logging system with three levels defined at build time ("Errors only", "Warnings and Errors" and "Full Log")
  • Ray depth and volume depth are now seperated.
  • CMake now creates an example ".ins" file to render fireball.vdb instances
  • Assets folder is now relative to exe file.

Bug fixes and UI Improvements

  • Separated camera controls to a new UI
  • Fixed a bug in cuda module load with new JIT ptx merger
  • Fixed vdb file transformation matrix calculation if file comes from Houdini
  • Atmosphere precomputation is now done in 3D and thus faster

Installation

Download and extract the "vpt.zip" to a folder, which comes with pre-built x64 binaries and assets. Run the "test_vpt.cmd" to test the VPT with the installed "fireball.ins" instance file, or you can run the VPT without command line arguments. If you are unable to run VPT, please submit a bug report in issues

  • Volume instancing
    • Ability to render thousands of instances
    • Instances share common volume textures
    • Correct transforms rotations and scales
    • New Houdini plug-in for exporting instance files
  • Octree and BVH structures for fast ray traversal
